Stuff this project tackles is on my "I'll get to it after I retire" list - super awesome. Looks like this works for forced air HVAC as well?

The "Open Source" page on the dashboard site[0] links to this firmware but nothing about the server side. Firmware for the thermostat itself is a requirement, but without a dashboard it's still not really Free.
Edit: If I read closely I would have seen:
> The firmware images and backend API server code will be open sourced soon, allowing the community to audit, improve, and self-host their own infrastructure.

This comment says he is awaiting Louis Rossman’s acceptance of this code for the bounty he raised, pretty cool if this all works out!

I really hope this project succeeds. In some small ways I was involved with Gen 1 and Gen 2 and the teams that built those products really cared. I doubt they would have said turn them off.

There's none of us left at Google anymore... and they didn't listen to us when we were there.

Yeah, I figured as much. Sad day :(
For what it was worth, I really enjoyed helping everyone ramp up on NX. At that time in my career, I was ramping many similar groups up and many came from Apple and were experiencing sticker shock! (They bought the very best and it was not at all cheap!)
We talked about that and those in charge on my end were not at all happy with me showing people how geometry that normally requires a higher tier license to create, can be created with the base tier license, lol. (Mere mortals need that info because having the more expensive tool is not always on the table.)
Anyhow, stay cool. Maybe it will be different one day.
Please tell the others as you may encounter them, "That NX guy from PDX says, "Hi." You all may not know it, but I learned a ton from you guys. It was in the questions you asked and the processes you set up. I am applying some of that to my own projects today. So, thanks! ( way late! )

Have this be an add-on supported by HomeAssistant and I'm in

It's reliant on a bounty iirc for the server and device side code to be open-sourced. Will be about an hour after that I reckon and I cannot wait to contribute.

wish this could have been released prior to the google shutoff. But I am happy with the ecobee and its HA integration.

This person is a PHP programmer according to their LinkedIn profile. They are just using the existing OMAPLoader tool and does not seem to have embedded device programming experience. I am not hopeful they will be able to write custom firmware for the thermostats.

I see it as a great starting point.

I can't express how much damage Google has done to its reputation in my mind with how they EOL'd the online functionality of these devices. I have 3 of them. I will never buy a Google device of any kind ever again.

Yup. Same, though I've actually decided to only buy stuff that supports home assistant. I shouldn't have to depend on a corporate server at all, and especially shouldn't have to call out to an internet site just to control something local.

If your boiler supports OpenTherm then get this thermostat controller https://github.com/Alexwijn/SAT
Weather comp + low load comp + PID which means your room temperature works at the precision range supported by your temperature sensor. In my case, within 0.02 Celsius. Saves energy and makes your house more comfortable. Operated via home assistant.
