When the switch is off the lights are still on at probably 5%. Simple single pole install and only one I have this problem with maybe over 10 single poles dimmers already installed. Any ideas what is wrong. I may try uninstall and reinstalling but not sure if that will solve?
When you say they’re on at about 5%, that’s your estimation of the brightness, right? I’m guessing the hub/app is saying the dimmer is off?
Neutral or non-neutral?
Do you have min or max values set?
Does you installation have a neutral wire? i.e. Is the switch wiring:
Black to switch “line”
White to switch “neutral”
Red or some other color to the “load”
Or you only using the line and load connections?
5% is estimation. Hubitat does say off, Neutral, yes LED but I don’t believe the bulb is different than in other locations (since garage have not gotten a latter to check), I did try changing to smartbulb mode but nothing has been able to change off issue.
Black line, black load, ground, added neutral connector to neutral cap
Double check to make sure you don’t have the blacks reversed.
Set the min to 1 and the max to 99. See if you can dim it to off then.
If neither of those work, I’d try a bypass. LED(s), right?
You will most likely either need a bypass or switch out your bulbs with a different brand/model. I had the exact same problem, and from digging around other threads in here both the Dimmer and Switch leak a small amount of power even when “off”, which is enough to make some LED bulbs glow faintly (even when wired correctly and when using a neutral). For me, swapping out bulbs was easier/cheaper than installing bypasses.
What was particularly useful was looking through the bulb compatibility thread: Compatible Bulbs for Dimmer Switch (Gen 2)
for reports of bulbs that worked with a neutral and no bypass.
