I’m trying to add my IKEA Trådfri Tunable White Bulb E27 using the IKEA Trådfri App.

But after pairing it only shows “Unknown ZigBee device”. I can toggle the light on/off, but there is no way to control the dimming or warmness.

Am I doing something wrong?

During pairing the light bulb is approximately 5 cm away from the Homey controller.

Please advice. =)

Did you try the search function? This is already discussed in several topics, maybe your answer is there already:

Solved the problem by updating the firmware on the lamps, was using a pre 1.0.0.0 version.
