I have two nest thermostats, in two different location have been working
for months now all of a sudden they both will not show my WiFi , I have
reset modems I have other devices ring cameras no issue . Was ther some
software update.
So first time as temp going down turned on thermostat in living room
getter error N72 Power wire detected no connection to equipment. I
checked power with meter and I’m seeing 24v between C and R wire not
sure why exactly
