I installed a new LZW30 to replace a GE smart switch I somehow fried yesterday. That switch had been installed there for over 1 year with no issues. I was looking at wiring at the box and think I hit something…I don’t know…but the GE stopped working. I put in the LZW30 and everything is functioning at the switch and through smartthings.
However, the LED settings do not seem to work correctly. I put in a LZW30 in a different location and did notice the same thing, however that one I don’t really care how the led works so I have it on all of the time. For this new location, the switch is controlling outside lights that I cannot physically see unless I step outside. I want the led off when the switch is off and on when the switch is on so that I know those outside lights are on. I have found that the “led strip intensity when off” setting controls behavior when the switch is off AND on. If I set that to 0, the led is off when the switch is off like it should be but it also turns off when I turn the switch on. If I set that to 50%, the led is 50% when the switch is off and 50% when it is on. The only way I can get it to “work” right now is I set the off intensity to 10% then set the led intensity to 50%. I want that 10% to be 0 but if I do that it will turn of when I turn the switch on.
I have had similar results after changing the LED intensity when off setting from the default. Apparently, changing that setting hoses the settings for when the switch is on.
I resolved the issue by factory resetting the switch and then not touching the off intensity setting.
I have determined the led off intensity is what causes the issues. As long as that is set to at least 10%, the other parameter works fine. If off intensity is set to 0%, it ignores the other parameter. This should not be the case.
Interestingly, with the default “off” intensity setting (which I presumed would be off completely) the LED is lit very dimly when the switch is off. The room has to be dark to even see it, so it’s not really a problem for me.
I currently have it at 10% when off and it is the same (very dimly lit.) It is next to another smart switch with that led indicator off so I do notice it.
Is the one next to it an Inovelli switch? If so, how did you get it to be completely off? I have two in the same location and both have the very dimly lit LED when it’s off. I’d prefer it to really be off.
I would like to add that the dimmer (at least the reds that I have used in 2 different locations) does not have this issue. I have these set to 0% when off and the led is completely off. That setting does not affect the led when the switch is turned on.
