I am finding my Nest switching the heating on in the middle of the night
when the temperature is already above the set point. It recently
received a software update. I have carried out a reset and reprogrammed
it from scratch but that didn't fix it.
Ours was doing something similar, coming on four hours ahead of the set
point in the morning. Go to Settings on the app, if True Radiant is on
switch it off, then do a complete reset and enter your setpoints again.
I suspect this happened to us when ...
