Please update the non-dimmable lights to set:

    _attr_color_mode = COLOR_MODE_ONOFF
    _attr_supported_color_modes = {COLOR_MODE_ONOFF}

Please update the non-dimmable lights to set:

    _attr_color_mode = COLOR_MODE_ONOFF
    _attr_supported_color_modes = {COLOR_MODE_ONOFF}

Also in RflinkLight:

core/homeassistant/components/rflink/light.py

Lines 174 to 177 in 109bde4

	class RflinkLight(SwitchableRflinkDevice, LightEntity):
	"""Representation of a Rflink light."""

(It would seem that the hierarchy could be optimized)

Thanks, @epenet 👍

@javicalle I suggest that you create the follow-up PR as you are more familiar with the integration

Sorry, but RflinkLight also must be fixed (the COLOR_MODE_ part).
