Not all Tuya devices (even when labeled 'Zemismart') are exposed via the Tuya Zigbee to Matter Bridge (even with Zemismart M1 logo on the plastic box). And no one can say which devices are supported via the bridge and which are not... : (
Please update the 'Moes ZigBee Wall Switch 1/2/3-Gang' driver to version 1.1.0.
First, delete the device (use the red button "REMOVE DEVICE" at the bottom right of the page). Then pair it again - this driver should be selected automatically. If not, I will need the device detailed fingerprint - you can obtain it from the HE inbuilt 'Device' driver clicking on 'Get Info' button.
Let me know if this works.
Update: the driver is now available for installation via HPM :
