Bear in mind that as they age, you have increasingly unstable lithium bombs on your wall.

Nest smoke alarms were inspired and truly the best I have ever used. So pissed Google destroyed them.

Nah Nest was made by an ex Apple engineer, retained Apple's "philosophy" of locked down walled garden everything, and introduced the idea of cloud controlled home automation to the masses. Killed off the idea of smart thermostats and smart home devices in general having a local server that does everything in your own home. Fuck that shit.

Also, for something pretending to be eco friendly, the amount of disposable packaging it came in was disgusting. A fucking thermostat that had more packaging than an iPad.

I abandoned any attempt at interacting via the app and treat it as a normal thermostat.

I agree it’s a great product, although when Google took over I did start noticing some behaviors like heat suddenly getting cranked up high at weird hours of the morning.
