Same issue, gen 4, standard ac condenser and furnace, this is 100% a
software issue, so you don't need a photo, about a week ago? Maybe a
little longer, no power code. I want to say I saw an update and a couple
days after that it's like it would say ...
Same issue here. 4th generation nest. It started not cooling at night,
so I turned all of the "smart" features off and it's still not cooling
at night.
