Moes Zigbee Dimmer Module 2 Gang question

Hello,
I am looking at this dimmer from MoesHouse.
Can I connect a regular dumb switch to this dimmer? I understand it needs a momentary switch to be able to dim, but what would its behavior be with a dumb flip switch?
I cant seem to wrap my head around this…

Did you ever get this to work? I bought one but am having issues with controlling the dimming function. It dims up and down continuously depending on how I have the switch flipped.

Hii
please could you help me? I ask if the Moes wifi-RF 433 switches make 2 or 3 way multicontrol association with the Moes ZigBee switches
it is imprtant for me to be able to order ???
