I installed several of the microswitches by aeotec last weekend. I noticed that the led indicator is visible through the faceplate when lights in that room are off. Is there a configuration setting to disable the led indicator?
No, the LED is not configurable. A small piece of electrical tape will solve your problem.
It use to be that the LED was on when the switch was on, but I have heard that newer switches have the LED on all the time.
