I recently got some new Ikea Zigbee things:
Bulb: LED2201G8
Remote: E2002
Dimmer: E2201
Buld and remote came as set and may have been “pre-bound”. At least at some point in the past, it was this way in sets of remotes and bulbs sold together.
However: First thing I did was resetting each device and connect it do ZHA.
The (without further configuration) I discovered that both controllers control the bulb as intended. Dimming, color shifting works as it should.
But why? I didn’t do anything besides connecting the devices to HA (and set them all to the same room.)
