Last Notes npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker It's not every day that I order $300 worth of Raspberry Pi Zero 2 boards. 😅 People think these boards cost the MSRP of $15/each. The truth is one board is $25.82-$29.64 after tax and shipping. That's not with a power supply, SD card, case or anything. Just the board, and the higher side of that price range includes headers. This is why I order in bulk. While it does nothing about the sales tax, it does help with shipping costs. I then pass those savings on to people who want to buy a #HestiaPi npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker If you want to try out a HestiaPi without buying anything, as long as you have a Raspberry Pi lying around, you can! Here's a sneak peek of the upcoming release there needs tessted: https://community.hestiapi.com/t/debian-12-bookworm-image-testing-v1-5-dev/2104/40 Obviously it won't control your heating and cooling without the relay board, and you won't be able to see the LCD UI without the 3.5" LCD, but you can run the software and interact with the web interface. npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker I've been bustin' my hump for a couple weeks now, but I think I'm getting close to final testing. Yeah, testing. That's the part where we make sure everything works before we ship new code. I know, what an old-fashioned concept! I'm super excited about this next release. New features after over 5 years. Try getting that from a corporation. Ha! npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker I had an insane push this weekend to get #HestiaPi & #OpenHAB to be compatible with a heat pump HVAC system. I'm testing it by running LEDs through the relays to see when they flip on. I have one prototype that I manually configured. I have the basics down: heating, cooling, ruining the fan, 2-stages for both heating and cooling. Next up, boosting and tons of regression testing. I rewrote huge parts of many of the roles and made serious logic/flow changes. I need sleep too! npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker OK @nprofile…2m0q, I decided to take a stab at supporting heat pumps (building off the unreleased v1.5 image). It's a beast. So many rules need updated... heating, cooling, fan, humidity, hot water, sensor/setpoint changes, all the checks and protections, the initialization routine. Those are just what I found so far, there are probably more. 😮💨 When I'm done, I'm going to need a lot of help testing this, and not only with heat pump systems. This will require full regression testing for HVAC and EU (aka generic) modes too. #nevent1q…wtd2 npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker I'd love to add support for heat pumps. Their efficency is making them a lot more popular nowadays. There's just a lot to do. The new release candidate is stuck in testing with one person having problems, I'm unable to reproduce any of those problems, and I haven't heard back from anyone else. Then there's also the desire to have an option to run juat the UI on the thermostat and have the automation on another server. And another O/S upgrade. And the heat pumps And another hardware revision I'm going the best I can, but I'm only one person. 😮💨 npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker We're getting close to releasing a maintenance update. No functional changes, but it will extend the security updates for another two years. There's more testing to do, but hopefully that will go smoothly. I hope to have another update out soon after that, which will be the same deal: no functional changes, but yet ANOTHER two years of security patches! When I say long term support, I mean it! And I'm big on stability too. No arbitrary changes for no particular reason, no breaking stuff or taking away features. It juat works. Day in and day out. #HestiaPi #thermostat #IoT #OpenHardware #electronics #OpenSource #FOSS npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker So it's going to be one of those days, huh? Went to assemble a new unit and after soldering in a few pins, I discovered the bin of 1x20 header pins was labeled incorrectly. They're all 1x18 pins. Whoops! At least I didn't get all the way to the end before I noticed. A couple pins lost, most were salvaged. npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker Nice! It's unfortunate that the person running that website is collecting people's email addresses when clicking the "getting started" button. Glad to see there is a self-hosted option buried on the github page. Not sure why there is any other option... ☹️ npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker A rare look at the #EU version of the #HestiaPi with the 240V AC -> 5V DC power adapter (the black rectangle in the photo). https://image.nostr.build/42e577b8250dae28335eea2af3667f92da36faafea655f645dceec70807b9fc1.jpg Everything else is the same hardware. It also uses the same software, just different settings. I hate to ship these across the ocean, but there's literally not a single person, #hackerapace or #Makerspace in the EU who is willing to build these #OpenSource #thermostats. So I make them available, and ship them all the way from America. npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker I just found the @nprofile…pvzu episode about sovereign smart home! https://fountain.fm/episode/r8I8AbFqwJc5f8Y0UvCF Brilliant work lads! If you want an easy to use recommendation for getting started, I maintain an open source (hardware and software) smart thermostat. Just connect it to the wall and go through wifi setup like any corporate device except everything remains private. Very good for those family members who don't want to feel like they have to run a server and be an IT pro. The HestiaPi runs OpenHAB out of the box, but you could build an SD image to run HomeAssistant if you prefer that. For those who do like to tinker, the forums are full of people who have customizations. Build the hardware yourself, pay someone at your local hackerspace to build one, or if neither of those work, I guess I could ship across the ocean for ya. I normally only ship to North America, but I could make an exception. npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker If you're still in the market, the HestiaPi has this feature. You decide how far off from the set points is tolerable. npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker I make smart thermostats and they don't require the internet. They'll work fine when your local wifi is down too. This is the kind of reliability people should be able to expect from everything they buy, but it seems to only exist in open source projects. npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker The only smart home thing I have is the thermostat, and that's only because it's not corporate made npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker I approve npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker HestiaPi npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker Couldn't agree more about local control and breaking free of the big tech overlords! npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker Yes. It can be used without network capabilities. The software works with an ethernet connection using a USB on-the-go adapter and USB ethernet adapter, and that's how I do development. Unfortunately, there is a mechanical limitation that prevents the models that I make over ethernet. The connector for the LCD screen blocks access to the USB micro port. If you go without a screen, you could use an USB ethernet adapter. It'd be pretty weird to have a thermostat with no UI and it'd put you in a weird situation where a network outage would stop you from adjusting the thermostat, but it's doable. In summary you've got three options for a WiFi-free HestiaPi: - dumb thermostat - screenless thermostat - DIY hardware and using the HestiaPi software By default the pi will serve up a wifi access point for the initial setup, but if you hop on the community forums, we can help you disable that. npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker What do #Nest owners think about #Google's decision to not only kill support, but also make the smart thermostats into dumb thermostats? Is it fair for them to take away the features you paid for? Will you get another smart #thermostat from the same company again? Are you in the market for alternative #smart #thermostats? #IoT #tech #technology #PlannedObsolescence #waste #recycle #repair #repurpose #reuse npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker Help wanted: test the latest release of the #HestiaPi SD card image. https://community.hestiapi.com/t/debian-12-bookworm-image-testing-v1-5-dev/2104 If you have a device, plea help. We're trying to get more people to test this out. The new image should work just like the previous version except it'll get another 2 years of security updates. No new features, just stability and long term support. npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker Less than 2 weeks left until the old #Nest #thermostats go through their metamorphosis to become dumb thermostats. Honestly, it might be a win for the owners in terms of #privacy. But if they want a wifi enabled thermostat that is open source and will never abandon them like this, please suggest a #HestiaPi. You can make one yourself, buy a kit, or buy a prebuilt unit. If it ever breaks you can #repair it. If it doesn't do what you want, you can customize it. #FOSS #OpenSource #OpenHardware ❤️ https://support.google.com/googlenest/answer/16233096?hl=en npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker It warms my heart to hear from people who were about to build their own thermostat from scratch and then found out about the #HestiaPi project. Now they can get a leg up on their #thermostat and just focus on the thermostat rules instead of the #hardware, #software and so forth. Meanwhile, we get another collaborator and hopefully can integrate the new code that implements the additional features they want. win-win! #OpenSource is awesome. npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker Today I built and tested 4 thermostats and it took me well over 4 hours. Usually I'm faster, but an hour per unit is probably still a fair estimate. Off the top of my head, I'd say it's somewhere around 130 solder joints. The new board design allows using Pi Zero 2 boards with pre-soldered headers. That that'll cut out 40 pins that I have to do by hand once I'm through my current stock. If I sold more devices, I'd try creating a 3D printed jig to hold all the parts in at the same time. It just doesn't make much sense to do that when I sell so few units per year. npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker Just made a breakthrough in getting the v1.5-dev image created. It's now fully functional out of the box! Next I need to manually poke around and make sure the unnecessary services have been turned off. After that I'll send it to the community for review and testing. Once any issues identified are fixed, then it will be sent to the project creator for final approval. To people who expect software producers to dictate what users will get, this process may seem bureaucratic, but it's democratic! npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker Getting close to an updated firmware image based on bookworm. I have a #thermostat running with it, but I want to make sure the build process can be replicated in an automated fashion. When I die, I want others to be able to easily pick up my work. Plus, it'll be handy for the next O/S upgrade. After it's reproducable, it will still need to go through community testing. If everything goes smoothly, I should have a final release in the next few weeks. npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker Yes. In fairness, they did support it for a decade, but the design decisions made in 2015 sealed their fate. They're not going to keep running their servers forever. That's why the HestiaPi doesn't connect to any remote servers. It's all run locally so nobody can cut you off, not even me. That's simply a superior design. npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker Thanks for helping spread the good word. There's no ads for HestiaPi, no marketing budget, no sponsoring podcasts... just everyday people like you telling others. I'd much rather give people a lower price and have word of mouth advertising than charge more and have a marketing budget. The grassroots style fits with who I am, and I am NOT a startup founder, going into debt get explosive growth. I want something sustainable, not an exit strategy. If it limits my impact, so be it. npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker Big news: Permanent price drop & international shipping! Down to $150 fully loaded, assembled, flashed and ready to plug & play in North America. Also, I've enabled shipping to Canada and Europe. I hope I don't regret that. 😅 https://www.tindie.com/products/eternalsunshine/hestiapi-one-silent/ I'm ready to help people kick #Nest & #Google to the curb. 💪 Lets do this! #nevent1q…f4h2 #FOSS #OpenSource #hardware #OpenHardware #electronics #FLOSS #RaspberryPi #HestiaPi #privacy #freedom #FreedomTech #thermostat #BigTech #DIY npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker The joke's on me. I already have it priced ay $149.99 for the kit. Oh what the heck, I'll drop it another $15 so the assembled version is $149.99. #yolo Get it now before I realize I literally can't afford to keep doing this. LOL #nevent1q…f4h2 npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker And before anyone asks "what, are they supposed to run their servers forever without compensation?" 😭 No, they should design their products so they don't need to run a server forever for a bloody thermostat to work! 🔥 But if they want to push this flawed design, give people the option to subscribe to the service or not, and make it clear subscribing might not always be an option in the future so people understand what they're signing up for. 🧐 And if they can't do any of that, and it's cloud service of no changing the temperature with your phone, then yeah, I expect them to keep running the service until nobody uses it anymore. If that's 50 years later, well maybe they should have thought of that at design time. If they pick a flawed design, they should live with the consequences. npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker What's especially messed up about the Google Nest thing is that these are thermostats people paid $100+ for and they own them. They shouldn't get the rug pulled out from under them like this. #nevent1q…kgdj Customers should be able to expect that their thermostats will work as well as they did when they bought it. At a bare minimum, Google should release the server side source code so people can run their own server to maintain the ability to connect to their thermostat over wifi. Yeah, they've got my panties in a bunch by pulling stunts like this. This is rancid! npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker Next month, Google is going to make some Nest thermostats not-so-smart. https://www.tomsguide.com/home/smart-home/google-announces-end-of-support-for-1st-and-2nd-gen-nest-thermostats-what-you-need-to-know This can never happen with a #HestiaPi. It's not even possible because it doesn't depend on some third party cloud service. Everything is run inside your home, and it's yours, forever. ❤️ The HestiaPi is also #repairable and #upgradable. In summary, it's better by design. #OpenSource #hardware #OpenHardware #FOSS #diy #electronics npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker Once the current batch of components arrive, I plan on running the numbers to see if I can make a permenent price reduction. I've been getting killed on shipping prices, but ordering in larger quantities helps mitigate that. The other persistent problem is finding components in stock within 5-10% of the regular price. Building out a bigger inventory helps here too. I'm optimistic. My goal is to get down to $150. Stretch goal is to hit $129.99 (the same price as Google's cheapest Nest) npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker Thanks, but I'm not into the "buy & sell bitcoin to make a profit" thing. I'm not making these thermostats to try to get rich. I'm doing it so people have an alternative to the big companies who hoover up everyone's data, try to lock them into subscription services, and then end-of-life their products 3-5 years later. The only reason I started selling HestiaPi units is because the one person who was building them was unable to continue dedicating the time and effort to make them available to the world. My choices were to limit the project to people with the skills, time, and inclination to build their own, or start building them myself. You can see the path I've chosen and I don't regret a minute of it. I'm fine with being paid in bitcoin. I'd be happy to buy components in bitcoin. I'm just not into the trading thing. npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker Interesting idea and I think it could work well if I do a crowdfuning style marketing campaign to get a bunch of sales at once. Right now I sell about 1 thermostat per month, but it is not at all consistent. I might get 2-3 orders in a week and then nothing for months on end. I think the real answer is to dedicate more of ny time and effort to this project. If the volume was higher, I could keep making bigger orders, and drop the price as a result. I'm already doing that now, but very slowly. Thanks for the suggestion and inspiring me to think more about this. npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker I'm about to place an order for $700 in thermostat components. Weee. Stocking up like this always makes me a little nervous. What if people stop caring about open source thermostats? What if I just spent all this money on parts that will just sit on my shelf? On the flip side, what if I don't buy these parts? Then nobody can buy a pre-assembled HestiaPi, which means anyone isn't willing & able to make their own gets left behind. And that's why I keep doing it. Leave no one behind! #FOSS #OpenHardware #hardware #OpenSource npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker I am delighted every time I see efforts like this to mobile towards software that benefits them instead of benefitting big tech companies. npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker I'm working on a new release, based on bookworm (Debian 12). Looks like I might be making some contributions to the turnkey project soon. The wifi setting aren't sticking after a reboot. Not sure if it's related to NetsorkManager or not, still investigating. npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker The #HestiaPi is a #prime alternative to the corporate smart thermostats that you can buy on #Amazon. It's also on sale from July 8-11, because I want people to invest in a #sustainable #thermostat instead of #PlannedObsolescence. https://www.tindie.com/products/eternalsunshine/hestiapi-one-silent/ npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker Really? I can just send you however many sats I would have spent with my normal supplier and you'll make the goods show up at my door? npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker Nope, just Tor Browser as usual. npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker Is the site down, or does it require some special browser? npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker I'd like to try to support this #bitcoin circular economy thing. Is there anyone who sells things like SD cards, Raspberry Pi Zero 2 W boards, the little 3.5" LCD touchscreens, and other components I might need? npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker If people want an open source thermostat to go with your high tech heating system, I build the #HestiaPi thermostats. I'd be happy help test and maybe try to get the pi speaking zigbee, but I can't afford a $500 heater. If you're interested in collaborating, maybe I could send you a complimentary HestiaPi? My motivation is that I want people to be able to have nice things like wifi enabled thermostats without having to give up their privacy. npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker It will increase contributions from me. Haha npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker The latest release of the #AirGradient firmware removed the code that phones home to the company servers even when you check the to to explicitly tell it not to do so. This is a big win for #privacy and #SelfHosting! https://github.com/airgradienthq/arduino/releases/tag/3.2.0 I plan on flashing this onto my device and testing it to verify nothing was missed. #tcpdump and #wireshark are my friends. 😄 #security #cybersecurity #infosec #OpenSource #OpenHardware #electronics npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker hestiahacker - Instructions has been merged into the development branch. I've submitted a PR to add some text about how to contribute back to the project. #nevent1q…c0gm npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker This doesn't have anything to do with the #HestiaPi (yet 😉), but AirGradient is one step closer to fixing their compilation instructions. This is exciting news because once their code is modified to stop phoning home to the company's server, I plan on adding documentation to the HestiaPi project on how to configure the #AirGradient ONE to act as a remote temperature and humidity sensor. If you've ever had a #thermostat mounted too close to the door, you understand why this is important. npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker Commercial IoT is just bananas. I fight against this with every fiber of my being.✊ I don't make beds, but I can at least give you a network accessible thermostat that doesn't spy on you or go End of Life after 3 or 4 years. 🫶 npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker If this is the kind of project you want to support: 1. Build or buy a #HestiaPi 2. Tell your friends 3. Contribute: bug reports, beta testing, documentation, #code, answering questions on the forum, or #building hardware for others We don't currently accept monetary donations (but you can #zap me personally if you'd like). I have been supporting this #hardware for over 5 years now and want to keep doing so as long as I can. Having more people contribute makes it easier. Having more people buy hardware let's me buy in bulk & cut prices. npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker I've spent a lot of time not just thinking about this, but living it. I've had the core of the #HestiaPi (#OpenHAB) abandon support for all versions of Java that can run in a Raspberry Pi Zero W. 😩 So now our project is at a crossroad. How do we proceed? It'll run on the Pi Zero 2 W, but what about all our original users who have a pi Zero W soldered onto their PCB? I think I see a path forward that will let still use the existing #hardware & OpenHAB. It'll be a lot of work, but I think we can do it. npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker #RaspberryPi may have their own problems, but they've been solid on supporting both their #hardware and #software. They even publish a minimum number of years they are going to keep producing each model of hardware. This allows projects to plan around that, which gives rPi a leg up when it comes time to decide which hardware to use. I hope you enjoyed my reflections on the state of long term support and comparing commercial IoT to #OpenSource #IoT. npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker hestiahacker - LTS for hardware is brutal. CPUs get discontinued all the time. The same is true for small board computers (SBCs). For example, the oDroid SBCs looked promising but they never got their kernel patches upstreamed nor did they port their patches forward to newer kernels. So you could only run them with an old kernel that's no longer supported. They ended up abandoning those models of hardware all together. Now they have new models. How long do you think they will support those? Probably not long. npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker What can be done about the #OpenSource world to make things more #sustainable? The biggest thing, by far, is to make things as simple as possible! That means you will inherently have fewer dependencies. Depend on libraries that have long term support. Contribute upstream whenever possible. Mainly code, but if you are selling #hardware, money too. npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker So what can help with the long term support (LTS)? There's really no helping the commercial world as long as they're trying to make a profit. The limited exception would be companies who not only make this their central business model, but also establish a track record of delivering on that promise. There are almost no business who have managed to pull this off. They used to be more common, but people are either unwilling or unable to buy the higher quality stuff these days. I could say a lot more about this, but I digress. npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker In the case of #OpenSource projects, it's a little different, and some projects are great at long term support. The challenges are that the #software and hardware that they depend on frequently stop getting supported. At that point, do they spread people thin to stay doing long term support for all the things they depend on? If it's #hardware, that's probably not an option even if you have dozens of volunteers. It's still a cost problem, but the cost is people's time, not #money. npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker It's also important to acknowledge that there are some places where both commercial and communuty based projects struggle, such as long term support (e.g. 10+ years). In the case of commercial products, they have a strong financial motivation for you to buy the next model, so working to extend the life of existing products isn't a strategic investment of their time and money. Plus it takes a huge amount of sustained effort for years to build a reputation of supporting products for a long time. npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker Here are some lesser known differences between an open source #IoT project and a commercial IoT appliance: 1. Support - #OpenSource projects field questions. Actual humans, taking the time to understand your questions and answer them! 2. Repair - Again, people will help you fix things 3. Less #environmental impact - Fewer things ending up in the landfill on account of the repairability, often times they have more localized production, less shipping, etc. 4. Customizability - that's something rarely found in commercial offerings npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker I have one clicky edition #HestiaPi left and I'm having a blowout sale.

Tapping the screen causes it to turn back on. There's a writeup on the community forum which I will be including in the owner's manual. #OpenHardware should be #hackable like this. I also plan on making this possible to do without hardware modification to the #HestiaPi on the next #hardware revision of the PCB. #OpenSource npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker hestiahacker - I've been trying to recreate another person's work with a more expensive LCD touchscreen that is able to turn off its backlight. They are using different #hardware and #software, but have been very helpful in posting about their work and sharing scripts. I think it will be possible to get it working with the #HestiaPi if I do one small hardware modification. Can't really be sure until it's tested, but I'm hopeful. If I get it, instructions will be added to the owners manual. ❤️🙂 #FOSS #IoT #OpenSource #OpenHardware npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker I shipped out an order today and thought "Gee that street name looks really familiar...". Checked my order history and sure enough a repeat customer. Anyone should be happy to have a repeat customer, but it REALLY says something that someone bought two thermostats. It's not like a thumb drive where you could always use one more. Presumably it's a gift, because if it broke they probably wouldn't be buying another of the same make and model. Besides, I'm pretty sure everyone who has problems reached out to me. So I'm pleased as punch today. Thank you, customer who shall not be named. You made my day. npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker It doesn't look like this tiny bag would cost over $1000 retail, does it? https://image.nostr.build/221f1a7a05e278d7b085a19dc1836fdfe67bfa4ae4bbc81222d6f0547687cc4c.jpg The comparable sensor from sparkfun is $21.50 (and they're sold out)! https://www.sparkfun.com/products/13676 npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker I'd suggest checking pin64's site before chiming in here. They already have lots of hardware available and more in the works! For example, they annlunced a new IP camera last week: https://pine64.org/2024/11/21/november_2024/#pinecam npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker If I were to take on another #OpenSource #smart #IoT device project to liberate people from their technical overlords, what should it be? I'm looking for inspiration. I'm not ready to take on another project right now, but I might be soon. The main catches are: I. Existing project (I'll search for one, and I'm flexible on this point) II. Not already available for purchase III. Something I'd personally be willing to use npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker Sometimes when you take a chance, it works out. Other times, it doesn't. I recently designed a temperature/humidity board, got PCBs made and tried to assemble them. None of them worked. Like, at all! So I redesigned it, making it simpler and tried again. Another 100% fail. I had someone review my design. He said it looked good. Maybe it was manufactueing errors? I'm pretty good at soldering, but yeah maybe... So I took a big chance and dropped $250 on machine-assembled terperature sensors boards. Of my design really was good, they should work. Otherwise I just spend a bunch of money to ship e-waste half way around the world. They arrived today and they work! Whew! I was really nervous about that one. This batch was about the same price as the cheapest pre-assembled board that I could find. If I can scale up from 50 boards to 250, I could have a very nice price. At least 10% cheaper than market prices. Of course I'd also have to pay $1200 up front and probably never sell them all to break even. So I'll probably stick to the "small" batches for now. #electronics #manufacturing #learning by #failure npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker I'd love to see someone make a LoRa add-on for the Air Gradient Open Air.

If successful, it'll lower the cost of all models of the #HestiaPi. At the same time, it will also help alleviate supply chain issues. If unsuccessful, it's a lot of money down the drain.

I'm not super interested in posting to 99 experimental platforms that doesn't even work well, let alone have the potential customers browsing the marketplace. I feel like an #OpenSource #smart #thermostat is something that could be popular among the #FreedomTech and #SelfHosting people on here. No 3rd party servers. No power company reaching in and adjusting your temperature. You control everything. Proofyou can still have nice things without giving up your privacy or succumbing to the corporate overlords! And they're just the type of people to be early adopters of a p2p marketplace. So I am holding out hope. npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker I got an order for a #HestiaPi kit today. The payment processing fee was $4.07. According to bitcoinfees[.]net, the payment processing fee would have been somewhere between $0.27 and $0.91 if it was made on-chain. Honestly, this doesn't seem like that big of a difference. Sure, it could have been $3 cheaper, but on a $120 thermostat, that's not a huge deal. Adding in the fee to Tindie, we're now up to just over $10 for them to host the website, deal with the order tracking, email me when an order comes in, emailing the buying when it ships, and so on. Also, Tindie has way more people looking at it than any Bitcoin or Monero marketplace. Plus, people feel more comfortable if there's a company inbetween them and the buyer so they have someone to turn to if they get ripped off. Whether that's justified or not doesn't really matter. Don't get me wrong, I'd prefer a p2p based system with a mediator that only steps in if there is a dispute. I'd also prefer to be paid in Bitcoin on Monero. OpenBazaar had this (at least for Bitcoin, not sure about Monero), but it never caught on. Perhaps they were too early? Heck, it might still be too early now. I'd be happy to pay a fee to the platform to host all this, just like I do with Tindie. It'd be a valuable service and they deserve to get paid for providing it. **sigh** Maybe someday... npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker I learned that I shouldn't try to solder under-component pads that are 0.35 mm wide again, and that on pins that small, the solder masks will overlap. Success, I guess? npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker I'm not familiar with yoyr systems over there, but the #HestiaPi works with the 24VAC systems in America, or the 240VAC systems in Europe. As long as the HVAC system is relay based and not something like ModBus, it should work. HestiaPi.com has more info, and I'd be happy to field questions as long as you are patient (I don't log onto social media very often). I don't do international shipping anymore, but I'd be delighted to have someone willing to build & sell them down under. That's really the dream for open source hardware: produced locally, with a portion of the profits going back to the creator and maintainer. npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker I designed my own #PCB for the #BME280 sensor (#temperature, #humidity, and barometric pressure), and the design is solid, but assembling it by hand is too difficult. After 6 attempts and a bunch of rework, none of them were functional. Too much solder in one case, which shorted things out. Not enough in another case and the sensor came off. Some other error in another case were it read 32°F (incorrect) and no humidity reading. So I'm giving up. A failed experiment. #electronics #hardware #GrowNostr npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker I'm working on a new #prototype for the #HestiaPi #PCB. All revisions up to now had some extra long headers (but not too long, or the case can't close!) which connected directly to the touchscreen. This meant you had to line up the pins perfectly while putting on the shell of the case. It it tedious the first few times. This #experimental version uses a ribbon cable instead, so you attach the screen before attaching the cover. https://image.nostr.build/3c9fa5bfa3f8539a400313d248a5acfedc21e423888562fd8e6ce06f7044e756.jpg Pic is peeking in through the side of the case. #IoT #thermostat #OpenSource #hardware #OpenHardware npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker To give you an idea of how much international shipping costs, I paid $8.85 the other day to ship a #HestiaPi. Shipping that exact same package to the UK would be at least $30.45. Speedier shipping would be $10.25 domestically, but $66.25 to the UK. On top of that, the buyer would have to pay about $30 in taxes (VAT) to pick it up in the UK. That's $51.60 that could be saved if the same thing were made by a local hackerspace. And if there's a problem, it won't be $30-60 to ship a replacement part if it was produced regionally! I shipped a unit to Canada and that was also over $30, so this isn't just a trans-Atlantic problem either. I've paid and extra $60 to have a replacement screen sent directly to a customer in Europe. Even then it took over 4 weeks to get there. This is why I don't ship internationally anymore. I've been burned too many times and the customers don't get the level of service they should expect. So I'm trying to find a better way. npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker Call to #hackerspaces & #makerspaces around the world, lets join forces!

Replace the dreaded LCD pins with a ribbon cable 2.) Swap the reset switch out for one that is compatible with both the #RaspberryPi Zero W and the Zero 2 W, and 3.) Allow using pi boards with pre-soldered on headers The first one is the cause of the the most complaints: the cover is hard to put on while aligning the LCD pins at the same time. The other two are about making it more accessible to #DIY & replace parts if needed. I spent $50 on these prototype boards to learn that 8 holes are too small, 6 are in the wrong location, I don't have double stacked 90° headers that I thought I had, and I shouldn't have soldered that ribbon cable in place.🤦 If I order another ribbon cable ($20 after shipping), I should be able to hack something together with the current version to verify there aren't any other problems. Then another $50 for an updated board design and I will have a candidate for the new design. Hopefully all the changes I make will be perfect. 🤞 Best case scenario: $50 more on boards, and $50 on ribbon cables and headers before I have a functional unit. I already have all the other parts. So probably about $200 in total to make this new revision. #ROI will be about 20 units, which is about 2 years at my current rate. (I make $10 profit per thermostat, which typically gets eaten up by me having to re-ship screens, cases, etc. when things go wrong.) #electronics #prototyping is expensive! 💸 npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker Also, I saw that there was one order that appears to have come from #nostr (thanks HTTP referrer headers!).

I don't like the noise, but some people find the click to be satisfying. The story behind the clicky edition was that Omron discontinued the solid state relays we were using and so they kept getting harder to find as retailers sold out. The clicky version was created so we wouldn't be relying on this hard-to-find part. It was also supposed to be cheaper, because the traditional relays are about 25% the price of the silent ones, and that adds up to about a $16 difference. However the clicky version required an extra 20 surface mounted components which ad up and make assembly take longer, so it didn't actually save any money and actually took more time. If they were made in huge quantities and assembled by robots, the clicky version might still be cheaper. At any rate, there was no parts availability problem. Later, I found a perfect replacement for the solid state Omron relays, made by Panasonic. That resolved the parts availability problem, and now we have 2 models. So there you have it, the legend of the clicky edition. 🙂 npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker #October is #CyberSecurity awareness month, so I decided to put the #OpenSource smart thermostats of #sale.

Done in KiCAD instead of some online tool (eliminating the risk of not being able to modify the PCB if the site ever goes under or discontinued their free tier, etc.) The next question is: does it actually work? The components I'll need to test it should arrive in the next few days and then we will find out. #OpenSource #IoT #hardware #FOSS #software npub1ydhmq6k7zshd5chdfrmpqpy44jyn02z7amw98knaqascw2flnpzq5serpq Hestia Hacker AirGradient answers the question about why they don't have any salespeople: https://www.airgradient.com/blog/why-we-dont-have-any-sales-people/ It's a good little #philosophical read. #engineers #engineering #FOSS #hardware #OpenSource #OpenHardware #GrowNostr #sustainability
