Hi @chachou1982,

Thank you for posting in the community. I’m sorry to hear that your Nest Thermostat is offline and showing a “no power to R wire” error message. I understand how important it is for you to make your Nest Thermostat work. I'm happy to assist.

To gather the necessary information, please answer the following questions:

What type of Nest Thermostat do you have? The following article might be helpful: How to tell which Nest thermostat you have.
Have you checked if the breakers are on?
Have you had any power outages in your area recently?
When was the last time your HVAC had maintenance?

I'll be waiting for your reply.

Best regards,

Derick.
