@tim.ocallag please try the development branch link here : Zemismart Zigbee 1/2/3/4 gang light switches - #36 by kkossev
I've tested it with a similar switch ( Tuya Smart ZigBee Switch Kinetic Self Powered Wireless Switch (no battery) ) and it works OK for my device. Can't see a difference between 'toggle' and 'state', but 'momentary' works just fine.
