I have two wireless dimmer switches installed with overhead can lights (4) and wall sconce lights (2). They've turned on randomly at full brightness several times, including the can lights turning on at full brightness last night at 3 am, the second time this has happened in the middle of the night. Clearly not acceptable for this kind of product. My wife basically wants them ripped out unless I can guarantee this will never happen again. There's many other reports of weird behavior, so is this a common problem? The hub is just outside the room. Can the switches respond to random noise and turn on without the hub sending a signal? Either way, how do I fix this?
