I have 2 smart plugs plugged into 1 dual outlet. One of these controls a lamp. The other controls the wall wart for a tablet. I turn the tablet on when motion is detected in the room. Everything works ok.
But sometimes when the lamp is on and the tablet plug is tuned on the lamp will flicker. I can’t seem to find a reason for this and was wondering since the 2 plugs are right next to each other if there could be some interference? It doesn’t happen all the time, but often enuf to make me wonder.
