The main thing slowing down adoption of open source smart thermostats is that people don't know they exist.
The #HestiaPi has is about the same price as the Google Nest was, and having been around for 5 years, we've already outlived most of Google's products!
If you like the idea of having technology that isn't run by a mega-corp, isn't harvesting your data, doesn't require their cloud to operate and doesn't get discontinued, please spread the word about HestiaPi.
We are so unstoppable, neither the founder nor myself could shut it down even if we wanted to! That's what open source brings to the table!

Google commits to supporting Nest smart home devices for 5 years
Nest speakers, cameras, thermostats, displays, and more get solid support windows.
No, seriously though, I only have one gray case and I don't plan on making any more. I'm not even sure why I have this one to be honest.
And just in case anyone actually wants this, I put an option for a silver case in the store. The case you see is what you get.
I'm sure evels will rise over time, but considering I only sell one unit every couple months, it's going to be a while. I don't have the time to run a whole advertising campaign or anything like that.
I just want people to be able to have an #OpenSource #thermostat without having to source parts, order custom PCBs, solder them together, hope that they work. It should be easy to choose #FOSS #Hardware, and the software should be easy to use and reliable while respecting your #privacy!
I'll die on this hill.
