The new NEST GEN 3 thermostat was installed but will not connect to my
WIFI. It says battery low. It's been installed for about one week now
and still no movement on this message. no other error messages show up.
Just got off a chat with Google support and while troubleshooting the
issue with them I came across: no C wire connected, but also error code
N72 - Wiring Report - Power wire Rh detected, no connection to
equipment, learn more at nest.com/n72
