I am in the same situation. My red switch does not turn off the load. I have tried the hardware reset recommended (hold config for 20 seconds) but instead of the LED turning red, I have it turn green after about 10 seconds, then yellow after another 10 seconds, the finally purple.
I have tried tapping config 8 times to toggle local control, that didn’t make a difference.
Interestingly enough, before I excluded the switch I have tried toggling the “smart light mode” even though it only controls a couple of plain old LEDs, and that made them brighter.
I pulled your posts into a new thread since your problem is with a red 2-1 and the previous thread was for a red (gen 2) relay switch. They have different button combinations and settings so those techniques from that post would not apply to this one.
Hopefully this will help get you some more visibility on the issue too.
Are you using a quick down paddle press to turn off the dimmer? I’m asking because some incorrectly thought the dimmer would turn off by holding the down paddle. When you do that, it will only dim to the lowest level, but not turn off.
As a double check, look at the switch’s status in the hub to make sure it is really off.
I don’t believe this is the correct method to factory reset it. I thought it was config+up paddle then release paddle then config button (or vice versa). That’s the way it is for Blues. The old Gen 2 reds were hold config for 20+ seconds.
It’s certainly possible it’s busted, but I would expect that to end up with the load not turning on, instead of the not turning off behavior you’re seeing here because the 2-1s don’t use a relay for driving the load.
I have the same problem for more than a year now. Already spoke with Eric and Customer Support, tried everything: factory reset, installed a capacitor on the load side, firmware upgrade, etc… nothing worked.
The RED or BLUE on the “dimmer mode” keeps “leaking” some current to the load side when it was supposed to be off.
The only way to turn the load off is changing the switch mode from “dimmer” to “switch only”.
