It said: E74, wiring report, no power to Rh wire detected.

 I don’t know why, It’s working for 4 days, all of sudden it stopped.

I am having the same problem.  Adding to that, this is an off and on situation, with a 30 to 40 minute cycle.  The thermostat comes back online and runs the A/C for 30 to 40 minutes then goes offline with the E74 error code again.  Also, the thermostat is always offline in the app now.
