Hi,
For controlling eTRVs under SmartThings, you’d need the ScheduleTstatZones smartapp which can leverage all your ST connected temp/motion/contact sensors to adjust your zoned rooms’ setpoints. The smartapp is based on the concepts of rooms/zones/schedules. The smartapp can create virtual zone devices which allow you to set different sepoints (offsets) for your colder/hotter rooms.
There are many features & use cases supported by the smartapp, refer to this ST community forum thread for more details:
Regards.
