I’m having an issue with my compatible Honeywell Home thermostat. Who should I contact?
If the issue is with the thermostat itself — such as how it works with the Resideo app or a hardware issue — please contact Resideo customer service directly, either by calling 1-800-468-1502 or by starting a live chat on their support page.
