Have a 2nd iPhone which I want to also use to control thermostat
settings. Thermostat shows it connect to an account (an iPhone) but
provides no entry key value. How do I obtain the Entry Key? Can only one
phone be used?
Answer does not solve problem. Found "Home/Away Assistant" but offers
nothing. No entry for "Family". I do not have the current version of
Nest thermostat. Perhaps that is part of the problem. How do I determine
which version I have?
