Hello Mikej7,
Thanks for reaching out to the Nest Community. We're happy to help you with your thermostat turning on and off randomly. We will work together to solve it.
To give you the most accurate assistance, could you please provide photos of your current wiring? This will allow us to compare and identify any potential issues.
You should find a camera icon or "Insert photos" option to attach the images. If you don't see this on your mobile device, please try using a different browser or a computer.
We look forward to your response and the photos.
Regards,
Kevin
