Thanks,
Conclusion: Using the “Aqara T1 relay” in a direct Zigbee connection to Homey with the Aqara App ([APP] Aqara & Xiaomi Smart Home - Simplify your life with a smarter home) gives a richer experience than using a Matter connection over the “Aqara M3 hub” to Homey.
Maybe you can change the options how the Relay is reported to Matter (as a Light, Cooker, Heater, Fan, etc…) in the M3 configuration?
