Thermostat says E4: No power to the Rh wire

[Andy6]

Out of nowhere my thermostat popped up with this error:

Thermostat says E4: No power to the Rh wire

I have charged the thermostat manually, I have tried to reset, I have checked the condensation pipes for clogs…  all with no success. I have checked YouTube but everything talks about HVAC connections and wiring in the nest- mine is on a stand and isn’t connected to HVAC system. 

Welcome any ideas to help fix!

My Nest has same message. Did you manage to resolve ? 🤷‍♀️
