I see one sensor is not setup correctly:
2021-06-07 19:36:26 ERROR (MainThread) [custom_components.huepower.sensor] Light not supported: ('No lookup file found for mode', 'color_temp')
. Need to have a look into that.
The other sensors should be created correctly. I also see it is looking up the power consumption correctly. If the sensor was not created this should not happen.
Could you check in Configuration->Entities if you see some sensor entities there.
The naming should be the light entity name postfixed with _power
. So in your example the sensor for light.bedroom_ceiling_light
should be sensor.bedroom_ceiling_light_power
