Livolo zigbee switch with zigbee2mqtt: I see state but cannot control the switch

Can you shortly describe how you made it work? I’m currently waiting for my switches to arrive. Or maybe you can point me to the corect thread?
What i want to know is how you made the pairing?
Thank you!

L.E. Do you use a certain Livolo switch or you made it work with all of them (1 gang and 2 gang or just the T1000)?
