RF433 On/Off/Dimmer switch to control Philips Hue lights.!!

[waaren]

I'm running Domoticz on an RPi3 with RFXtrx433E. I've also added my Philips Hue lights to my Domoticz.
What I'm trying to do, is to control my Philips Hue lights with an RF433 switch.
I'm using this Nexa WT-2 wallmounted switch. This way, I can control the on/off function of the Hue lights with an actual physical wall switch I'm wondering, is if it also would be possible to use the dimmer function in the wall switch to dim the Hue lights as well?

Can you please explain in a bit more detail how you set up the RF433 switch to control the Hue lights. Maybe that will help understand what would be possible to extend the functionality to dimming as well.
