Nest Turned Itself On, Even Though I Had It Off

I turned my Nest off (set the mode to Off) yesterday afternoon. It looks like it turned itself on at exactly midnight last night. Why? I only noticed because I was freezing my ass off!

Nest tstat has 5 modes.  They are listed here:

Eco mode is equal to all other modes.  If the tstat thinks you are 'away' it will automatically launch Eco mode and you are at the mercy of whatever settings are in there even though you didn't know it existed and have eco mode disabled (/not set up).  I put mine into 'heat only' mode and in all its wisdom, nest decided it was time to blast the AC (-5 degrees outside).

 

Disable everything 'eco' or 'away' in your settings and when you turn it off - it should remain that way.
