FAQ: Are Smart Bulbs Repeaters? (Updated 2019: the new answer is yes, but may be inconsistent)

@JDRoberts

But they introduce additional protocols and there’s also the question of whether they are really going to be left on power all the time

So If the bulb is switched off using a “dumb” switch which cuts power to the load/bulb there is obviously no repeating done right?
