This device got paired very easily and working fine as ON/OFF Switch but i wanted to use it as a dimmer switch since main purpose to but this was to use it as a Dimmer.

I can see below response from device

Since it as State as topic it ccan be used as ON/OFF device,
Is there any option to add brightness topic aswell since it is supported by hardware.

PLease assist.
