I am the primary maintainer of the (hestiapi.com), which is an thermostat. I also build and sell the hardware to make the technology more accessible.

If you like what I do, please consider speading the word, buying a unit, or sending me some digital currency. The software maintenance alone is a ton of time & effort and hardware sales barely break even.

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!

A rare look at the version of the with the 240V AC -> 5V DC power adapter (the black rectangle in the photo). 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, or in the EU who is willing to build these . So I make them available, and ship them all the way from America.

What do owners think about '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 from the same company again?

Are you in the market for alternative ?

Help wanted: test the latest release of the SD card image.

community.hestiapi.com/t/debia

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.

Less than 2 weeks left until the old go through their metamorphosis to become dumb thermostats.

Honestly, it might be a win for the owners in terms of . But if they want a wifi enabled thermostat that is open source and will never abandon them like this, please suggest a .

You can make one yourself, buy a kit, or buy a prebuilt unit. If it ever breaks you can it. If it doesn't do what you want, you can customize it. ❤️

@controlc I do not. Everything is open source, so anyone can build them.

Furthermore, I'd be willing to work with any Makerspace, anywhere in the world to have build these thermostats.

My mission is to get this technology into the hands of anyone who wants it. So if you have a Makerspace near you and can convince them to chip in on this effort, please get us connected so we can make it happen.

It warms my heart to hear from people who were about to build their own thermostat from scratch and then found out about the project.

Now they can get a leg up on their and just focus on the thermostat rules instead of the , and so forth.

Meanwhile, we get another collaborator and hopefully can integrate the new code that implements the additional features they want.

win-win!

is awesome.

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!

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. 😅

I have no intention of giving up, but even if I did, everyone's device would continue to work just the same.

Plus others could pick it up and keep updates coming, just as I did when the original creator wasn't able to dedicate as much time to the project. 💪

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.

mastodon.social/@hestiahacker/

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.

This can never happen with a . 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 and . In summary, it's better by design.

Had someone suggest having a longer lead time before shipping to try batch up orders and know that I won't be stuck holding the bag.

I have mixed feelings about it. On one hand, mitigating that risk sounds pretty good. On the other, I like shipping within a couple business days and getting people the thing they're excited about getting.

I think I'll keep shipping fast & risking holding the bag if/when the music stops.

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!

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.
