Aqara Dimmer Switch H2 EU

Last week I bought the Aqara Dimmer Switch H2 EU. The device works fine to control non smart lights as it just works as a normal dimmer. It’s visible in HA as a light so you can easily control it that way. But what i would like to do is to use the dial on the switch to dim zigbee lights. I think that should be possible with an automation but I can’t seem to find how to achieve this. When you rotate the dial it changes the brightness of light entity in HA. So i would like link the brightness of the switch to other lights.

I found a blueprint that did the job!
