We have a Nest thermostat, but we have all the smart stuff turned off. I don’t like things that think they are smarter than me (Lot of stuff, I know). If you want it to learn your daily pattern & adjust for it, you might like it….until you don’t.
I don’t want google controlling my home temp. But I am just a cranky old guy…..
I'm right there with you. I'll turn off whatever (so-called) "smart" stuff it does. (ssshhh) I don't know much about it, but I like being able to adjust temp before you get home from a phone. (like after a vacation or just a couple days away)
