Google announced the end of support for early Nest Thermostats in a support document earlier this year that largely flew under the radar. As of October 25, first and second generation units released in 2011 and 2012, respectively, will be unpaired and removed from the Google Nest or Google Home app.
Users will no longer be able to control their thermostats remotely via their smartphone, receive notifications, or change settings from a mobile device. End-of-support also disables third-party assistants and other cloud-based features including multi-device Eco mode and Nest Protect connectivity.


This is exactly why I didn’t buy one of these or the Amazon version. I didn’t trust that the devices would work as long as they could function and was correct.
I’ve got one but I bought it from Nest, not Google. TBH I’m surprised it was supported this long, not in a thankful way but because Google is so anti consumer. I didn’t realize the app didn’t work until I saw this post. I’m glad to find out now, not during a heatwave where I’m trying to cool the house when I’m driving home.
I bought one a bunch of years ago. Maybe 10 years. It worked fine. Did it’s thing. Then for no reason google chooses to kill it. Fool me once.
That’s kind of their thing.
I replaced mine with a Sensi. 4 months with Nest, and it decided to confuse hot vs cold signals. Middle of August, it tried to “cool” my house at 3am, instead turning on the furnace, and just kept on going due to the temperature rising. For a week straight, I awoke to 90 degree temps in my house at 3:30 to 4am, and a nice heating bill. I had an hvac friend come over ad tell me in fact, yep, it’s sending signal to furnace, not ac. He checked the wiring, all good. He admitted he knew little of Nests, but said only an idiot would design a thermostat that could allow for a hot/cold signal switch without rewiring.
Heat/cool wiring is rarely correct, many thermostats will have a software option to reverse the wiring.
Sucks that yours got reset for no good reason but it’s probably for the best
I mean, I’m not a trained tech, but it isn’t hard to open up the heat pump and look at wires going in and looking at the thermostat and making sure they match. Although I admit someone ran stranded wire instead of solid core (one day I might try to fish a new wire). For now I just tinned the ends.
I have a Sensi and didn’t program it correctly, though my wiring was on point. HVAC guy puzzled over it a few then called me over to show me what the cryptic options meant. Been solid for a few years now.
I’d like to see those options in the app, but if those were included people would fuck them up and blame the company. 🤷🏻
I got 11 years out of mine. I had been wanting to upgrade it because it did not accept sensors.
Does it suck that it was still functional? Yup.
I mean they could just unlock the dang things at let some industrious hacker make them useful again. Hell I’d pay like $10 for a firmware that would work with home assistant.
I would have paid for that as well. I would pay for that for my truck’s infotainment center as well.
Honestly I’d pay as much as $50 to unlock my Microsoft sync to CarPlay on my old explorer.
I think car manufacturers that put closed systems in vehicles and then abandon them should be required to either open source the system or push a final update that adds Android auto/apple car play (or whatever they are called)
