I want to create… something… that will allow me to change the mode on three thermostats with a single action.
My HVAC system is a single heat pump with dampers that control air flow to three zones. Each zone has a Honeywell Wi-Fi thermostat. The Honeywell TCC app is linked to SmartThings but I’m not using any SmartApps to control the thermostats.
Each thermostat can independently be set to heat or cool even though the single heat pump can do only one or the other.
When I have to change from heating to cooling and vice versa, I have to tap thru changing the mode in each of the three thermostats using the Honeywell TCC app.
I’d really like to create an automation or scene or something that would let me change the mode on all three thermostats at once.
I really don’t want to give over complete control of the thermostats to a cloud-based app of any kind. Not yet, anyway. Just a way to keep the three thermostats in the same mode and easily change which mode.
