Goofy bug just started happening to my old 2014 Nest Thermostat I've had for years. All of a sudden around 6AM to 7AM, no matter how cold it is outside, (like this morning it was 16 degrees F) it up and turns the A/C on, set to 70 F. I have NO routines set on any platform, app or ecosystem (not even in the Google Home app) to switch MODES.
It's been doing this for a few weeks. I have to manually switch it or it's colder than crap if I forget and go to work without checking. Yesterday I came home to it being 56 F indoors. No, this is NOT Eco Mode. It's actually switching out of Heat to Cool for no apparant reason. I can't find anything online and the only two Reddit threads are unanswered. I have nothing linked to Nest, and recently disconnected and unlinked both SmartThings (hub died!) and Phillips Hue (also died, thought there was no internet when there was). I have no other accounts linked other than C by GE and Merkury and that's just smart bulbs.
