Moes Zigbee Switch Without Line Out

I bought some Moes Zigbee wall switches in hopes of connecting them to my home power line, replacing my existing dumb switches and controlling devices via home assistant.

Example use case: 3-gang switch: 1 gang for ceiling lights and 2 gangs for electrical blinds (1 for up and another for down).

When I was connecting them, I realized that they only work when I connect line-in and line-out. My existing wall sockets don’t have a neutral line for the light switches.

This doesn’t fit my use case as I bought devices with more gangs than I have line-outs on each socket.

I made the mistake of buying them way before moving to my new apartment and now I can’t return them to buy scene switches instead.

The 2 gangs are recognized as this: Moes ZS-EUB_2gang control via MQTT | Zigbee2MQTT

Is there any way to work around this?

Thanks in advance.
