I own five (5) NEST thermostats .. Three in one home, see,y models which suffer constant internet disconnects…. I go away for months and rely on NEST to maintain my schedule, especially with regards to heat in Eastern winters…. So upsetmthst NEST is ...

My GEN 2 NEST works only from the APP - the face module slips - no rotation control - can I but a used model and simply install the working face module onto my existing working/wired plate -- plug + play?
