I installed the wifi switch next to the existing dimmer switch. When I put everything back together and turn the power on the dimmer light switch slightly sparks sometimes when switching on/off.https://media1.giphy.com/media/xUOwG9OSjZgd583sPK/giphy.gifIt’s hard to see in the video but the slight spark occurs in the toggle I’m pressing back and forth.What could be wrong? via /r/DIY http://ift.tt/2BPUADi
