Hi @TheLizard, actually the virtual zone devices should be able to integrate with AT as the devices expose the thermostatSetpoint capability. I know that AT uses the standard ST capabilities to interface with the devices.
If it doesn’t work, please check with the AT support why they are not able to use the thermostatSetpoint capability to interact with the zone devices. There may be other reasons that I’m not aware of. I don’t use AT at my home… On my side, I’ve exposed the standard ST capabilities that allow to do so.
Regards.
