I see people complain about Nest and the only thing I can think of is "what on earth where you thinking to have a door or thermostat that doesn't function without internet?!"
I live in a house with a Nest thermostat and Nest Secure and Nest x Yale door locks. The AC is on just fine, and the door unlocked just fine. (The door lock doesn't require an internet connection, unless you've enabled privacy mode for some reason.)
