Hey everyone, I’ve just installed a bunch of these switches and I’m trying to understand why on some I get a red blinking light, some I don’t, and I have the same LED bulbs throughout the house. The only difference being some have 3 bulbs in series, some have 1, some have 4, etc. can someone help me understand why the red light would pop up and also why some lights won’t turn off all the way while others do? Again, same bulbs, just different number of bulbs.
