Matter controller and driver ?

[jmarcgit]

Hi,

I would to create a module which observes attributes of a device and triggers relays when receiving notifications from the device.
I think it can be a simple controller but:
-it wil have to subscribe to attributes and/or events
-according to the values it receives, activates physical relays (2)

My goal is to monitor a thermostat which supports Matter controllers in order to drive a specific heater system. Is this possible ?
