Google announces 1st and 2nd gen Nest Thermostats will lose support in October 2025 – Ars Technica
So, on the one hand, they're not saying it'll stop working. Just that it'll only have more or less the same features that a non-smart thermostat has. But still – I'd be pretty irked, if I had one. This is, broadly, the peril of buying smart home gadgets. and why my rule of thumb is that I want them to be able to perfom most of their functions without internet access – in case the company behind them goes bust, and the infrastrcuture vanishes. But Google haven't gone bust. There's no suggestion that the couldn't, if they chose, keep these running. They're just not. Unimpressive.
