Busch Jäger 6715U + 6736-8x (RM01) brightness

Hello,

first thanks for your Work and support, great!
I have three Busch Jäger 6715U + 6736-8x devices. I can control this devices on/off as an switch and the additional buttons sends an events.
But i can´t send oder receive the brightness. Busch Jäger have three different types of Devices, Power Plug, Switch and Dimmer. I use the Dimmer but i cann´t control it or receive the brightness level.

Is is possible to support this future. it would be great and i can make an donation?
