Single virtual thermostat to control multiple physical thermostats

Configuration Frontend
1

We have multiple Honeywell Z-Wave thermostats in our home. I would like to use a single virtual thermostat on a dashboard to control multiple physical thermostats. As an example, if I set the virtual thermostat to 68°, I would like the Honeywell thermostats in the kitchen, living room and dining room to be set at 68°. If I change the virtual thermostat to 67°, I would like the kitchen, living room and dining room thermostats to change to 67°. Does anyone have any thoughts on how and might accomplish this?

Thank you.

What should the virtual thermostat report if someone manually changes the target temperature of one thermostat so that it’s no longer the same as the others?

Should it simply ignore the change or force it back to the original value?

EDIT

There’s a custom integration that lets you define a Climate Group (virtual thermostat that controls a group of thermostats). It might suit your needs.
