Hi all. New here and to Smartthings. This community has been VERY helpful in getting me started. Just setup my hub last night and installed a Leviton DZ15S-1BZ switch without any drama to control my ceiling fan light in my living room. The switch is single pole and is wired into a 3-gang panel. The second switch is also a single pole to control the same ceiling fan (fan itself) and the third switch is a 3-way switch that controls some recessed lights in my kitchen. The 4 ceiling fan lights (6w led) worked fine last night, no issues. This morning there is one bulb (out of 4) that now has a constant flicker. All other bulbs operate fine. I even switched the bulbs around and found the same bulb had a flicker no matter what “socket” of the light fixture I put it in. So to me it sounds like the issue is with the bulb itself and not the light fixture/wiring. Any thoughts? I brought the bulb in question with me to work today thinking I’ll swap it out at Home Depot hoping that would fix the issue. Wanted to hear from the experts here though first. Before I installed the Leviton switch, I would get a weird flicker/delay from a bulb or two. But that was just with the initial on flip of the switch. Has never constantly flickered like now. But can’t say for sure if that was the same bulb in question or not.
FWIW, my 3 gang panel is wired so the line comes in with the second switch. That line is pigtailed with 3 wires and then those 3 wires each run to all three switches as the line (hot). There are two other black wires in the box that are connected with a wire nut. I did not test these, but I’m assuming they are the other 2 line (hot) wires from the 1st and 3rd switch. Then the loads are ran from each switch as normal. From my research this seems to be a common way to wire a 3 gang panel. Just wasn’t sure if this could be causing my flickering issue in any way or not?
