i have been away and I switched my nest/boiler off completely at the main switch so no electricity going to it. On the last day we were away the schedule showed it was on from 00 for over 21 hours when it wasn’t all turned back on until around 17.00 that day?? Any ideas why this should be?
Thanks for reaching out. I'm sorry to hear that you're having an issue with your Nest Thermostat. I'd love to know more about this. Could you share a screenshot of the Nest Energy History for that day?
