We’re still collecting data and I’m actually going to start another one of those, “data collection” threads as the one that pertains to the On/Off actually helped the manufacturer a bit with their analysis.
However, our gut is telling us what @burns said in the second to last paragraph:
This is what it seems as there’s a built in shut-off feature that kicks on when the switch is overheating. Since it seems like when most people are setting maximum levels under 100, it fixes the issue, this makes sense.
The thing that’s throwing us off is there seems to be some low level Wattage loads that this is reported on such as @devanb mentioned
So, we’re trying to figure a common thread – is it the bulb compatibility? Something with how it’s wired (ie: single pole, 3-Way)? Not sure.
I’ll edit shortly with the new thread that I’ll create to coral all the data.
In the interest of not clogging up the other thread, could I ask a question to clarify what the problem people see is? It sounds like the dimmer is just turning off. I’ve reported a similar problem where my dimmer not only turns off but also becomes completely unresponsive unless power is pulled and restored to the dimmer switch (e.g., with the air gap) on two different dimmers: LZW31-SN with relay disabled spontaneously turns off with low loads
If that’s the same issue, I can add it to the data-collection thread. If it’s not (nobody above mentioned unresponsiveness, just “turning off,” which makes it sound like turning it back on lets it work normally again–which I can’t do) … then I’m still curious what’s happening but won’t clog up that thread.
ETA: Well… that was worth a shot but now I think it was just coincidence that for a long stretch (hours) after I twiddled parameter 8, I no longer experienced the problem. Because after a while I had period where the problem would happen but only very rarely, and now I’m back to being able to reproduce the issue almost on demand. So… There’s something else going on. I’ll post my data to the data collection thread when I have a chance.
Those experiencing this problem might wan to explicitly set parameter 8 (“auto-off timer”) to 0 for the misbehaving switch and see if it makes any difference. Yes, I know, 0 is the default. Ignore that fact. Do set it. When I set it to 0 on my switch, the problem became much rarer. Note that when I did it, I set it through Home Assistant, which presumably sent out a ZWave command to the switch. I don’t know if trying to set the parameter by doing a button tap-dance on the face of the switch would work.
I’d like to say that the problem was completely gone after the change, but alas, that’s not the case. Prior to explicitly setting parameter 8 to 0, I was able to reproduce the problem 100% of the time. After the change, I can reproduce it maybe only once in 10 times.
At any rate, if anyone else is able to reduce how often the problem happens by setting parameter 8 to 0, that would be a good data point for figuring out where the issue is.
I am having the same issue where the dimmer has the relay disabled and becomes unresponsive unless I pull the air gap. At that point it will work for a while and then stop.
I just wanted to update that I have not had an issue since my last post and I do believe the fix was reducing the power. This switch controls 6 LED down lights in our new construction home (year old). Its easy enough to pull them down from the ceiling so I’ll look at their make/model when I get home and update this post. I’ll also update the other data collection thread. I’m sure the total load is well under 100 watts.
I do have several more switches yet to install so I’ll update if I run into the same problem controlling 4 of the same down lights.
Yes, currently the relay will click when turning the dimmer On or Off when using a dumb switch (in a 3-way configuration). I believe a firmware change can reduce this relay switching to whenever the dumb switch is toggled (i.e. not when the dimmer is toggled on and off).
I finally decided to go with an add-on switch so that I can dim the lights at both sides of my 3-way configs. Using an add-on switch also removes the requirement for the relay to switch.
I think my issue is different from what is being discussed in this thread, but I just want to be sure. When you all say that the dimmer ‘turns off’, do you mean that it turns off the attached lights?
The dimmer is still operational at that point, such that if you sent it an On command or pushed the physical button on the dimmer to turn the lights back on, they come back on?
I’m having an issue where the dimmer just appears to be dead intermittently, the LED bar is dark and the dimmer doesn’t respond to commands from the hub or physical button presses. I posted about it the other day, but since I keep seeing this ‘random shut down’ or ‘turn off’ issue described by others, I wanted to be sure that isn’t what I’m seeing.
Since you are leaning towards this being some type of protection mechanism kicking in - can you (or the engineers) comment on whether or not there’s potentially a safety risk in using the switches for those of us who are having this issue? I’ve got 2 toddlers in the house who like turning lights on/off and would hate for this protection mechanism to not kick in when it should if there’s something triggering all of this.
Add me to the list of those with random shutoff. 3-way dumb switch config. Load is aprox 40w between 3 B30 bulbs.
It had been working for the last week and just started doing this today. I do seem to notice that if the dumb switch is in the on position then everything works fine. If I flip it to the off position and then turn the circuit on via the dimmer that’s when I get the issues. I did not monkey with the wiring at the dumb switch… perhaps I should?
Should we be contacting support for a replacement device at this point?
I’ve also experienced this randomly. One red series scenes in 3 way config with a dumb switch on the other end controlling 6 hue white bulbs. Single up tap turns on the lights, 2-3 seconds later the lights go out. I can single tap up and the lights come back on but then go off 2-3 seconds later. If toggle the dumb switch, the lights will then stay on when I up tap on the smart one.
Hi @zsdn6ubtogqk56, I have been using the GE 1st gen aux switch in my 3-way application and have had no issues. For the extra $20, I couldn’t pass up the opportunity to be able to dim the lights at both switches. I’ll be doing this for my other 3 & 4-way locations.
For anyone that is interested, my random shutoff issue stopped when I swapped my dummy switch for an auxiliary switch. I left my lights on all day, this would have shutoff my lights previously
@Eric_Inovelli - is there a fix for this using existing dummy switches? I have this in a 4 way setup and it continues to do this where it turns off the lights when you use the smart switch. I’m only running a 39 watt load as I swapped everything out to LED and this still happens unless I have my other 3 switches in a certain configuration of on/off. Everthing is wired correctly, according to the diagrams and the lights will come on for about 30 seconds to a minute, then they turn off.
For those of you who used aux switches to solve this problem, do they have to be Innoveli or can it be the GE ones?
Replacing my dumb switches with the GE 46199 Enbrighten Add-On Switch fixed the problem for me. Remember to change parameter 22 to 2 on the Inovelli switch to set it for use with an aux switch.
I tried the fix in the other thread but it didn’t work. For me, the 3 dumb switches have to be in a particular configuration of on/off or the Innovelli will turn itself off after a period of a few seconds. I’m going to try the add on switches and see if that will work.
That’s super strange. We can also swap it out with one that we’ve personally tested and configured to see if it’s just simply a bad switch too if you’d like?
