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.
I had the same issue. But i’ve set up scenes and use them in the automation. After i set up the scenes it now uses the last scene when turning on the lights.
@Marie11e could you explain in detail how you did that? I tried it but its not working when using scenes in automations, too. every time when i turn on my lamp with the home app using homebridge the lamp has 100% brightness and not the old state of brightness.
Light Support
If supported, lights will display brightness, hue, saturation, and/or color temperature.
By default, Homebridge will allow a color temperature between 50 and 400 mireds. You can override this for your specific light(s) by using homebridge_min_mireds and homebridge_max_mireds.
