Hello StuB,

Thanks for reaching out to the Google Nest Community Forum. I'd be happy to take a look at this for you.

Improper configuration could cause power-related reports. To isolate, could you share your old thermostat and Nest Thermostat's wiring setup? What's the message code or report you're getting? Also, gather the power readings in the Technical Info settings or Equipment settings.

I'll look forward to your response.

Regards,
Mark
