I am developing Smart Home skill for device that is both a light and a fan. I implemented both PowerLevelControllers and BrightnessController for it. However, if I have them both, power level commands in skill test apps are sent as BrightnessController directives. Thus, something like `Alexa, set <device> power to fifty` results in brightness changes.
What had I tried so far:
1. Adding PercentageController as PowerLevelController -> still changes Brightness.
2. Adding both catigories `LIGHT` and `FAN` for discovery. No effect, I assume this is just for visual sorting, but I had a hope.
3. Removing BrightnessController - power level commands started to work. However, I could also say `alexa set <device> brightness to one hundred` and this would modify power level.
How can I make them to work separately?
