Control dimming of Nexa WDR-1 with rfxtrx

Hi all,
I am totally new to HA but have managed to install it with hass.io and added rfxtrx.
Now I wanted to move my 433 devices from tellldus to HA and started with a Nexa WDR-1, a dimmable, built-in switch. It is found as a “switch”, but I change it to a “light” to get the dimmer-functionality, but it doesn’t respond to dimming instructions. It is possible to turn on/off.

Now I’m looking for information if this is possible at all, or if if someone has info on how to do it.

BR,
Tomas

So what happens when you change the light level from HA?
Anything in the log?

Thanks, good input. I will check the log.

Nothing in the log.
As I can conclude by this post, it’s not possible to dim this switch this way:
