Home app sets brightness to 100%


I just did a setup with a Pi, Hass.io, homebridge, conbee and at couple of Ikea and Hue lamps.
In Apple home app all the lamps show up nice and correct. But when i switch a lamp on it automatically gets 100% brightness. In elgato and koogeek app aswell as in hassio web interface it gets the last value instead.

Anyone got any ideas?
