Can I exclude my compatible Honeywell Home thermostat for central heating from a challenge?

Yes.

If you would like to exclude only your Honeywell Home thermostat from a challenge, you can do this directly from the Honeywell Home application (Resideo), independently of the other Hilo devices participating in the challenge.

If you would like to exclude all of your Hilo devices and your Honeywell Home thermostat for central heating, you can do this directly in the Hilo mobile app.
