/**
 * Users can add lights in their rooms.
 * Lights are devices like bulbs, LED strip lights, lamps.
 * Lights may support an intensity level (from 0% to 100%).
 * Lights have an internal state that can be changed and it must
 * be shown accordingly in the SmartHut views (house view and room views).
