Have you had any success to get things working Paal?
I bought a M2 Hub which really goes against reason buying the very expensive homey.
I can control the switch via ZigBee <> the M2 and then Matter to the Homey but it’s not perfect.
I have hue lamps and I wanted to be able to keep the relays of Sw1 & Sw2 closed then operate them as wireless switches so that I could keep the Hue working.
