I have a LZW31-SN that I use for the garage running a bunch of LED lights. Wired in as 3-way with a dumb switch. I’m using Home Assistant and Node-RED to do different scenes. I just updated from the old ZWave to Z-Wave JS, which went a little funny but things seem like they’re working now.
However, tapping “on” once is causing the garage lights to flash on and off very quickly (like 4-5 times per second). I don’t think it’s the Node-RED flow doing it. I think the switch might be misconfigured. But I can’t see what might be doing this.
Here’s the Node-RED flow… one top button press sends a brightness of 255, then 3 minutes later sends a brightness of 0.
I assume everything worked fine with the old integration? Verify parameter 22 is set to 1 (dumb switch) and parameters 21 is 1 for neutral and 0 for non neutral.
Is the dimmer neutral or non neutral? What’s the load in watts and the type of bulb(s)?
All else fails stop the node red addon to rule out that.
Hello @stu1811! Yes, everything worked fine before. I think 22 is 1 and 21 is 1 (it’s has a neutral). Usually runs just a few watts (less than 5?). LED bulbs… various brands… unchanged.
Same flickering happens when powering on via Home Assistant UI/Lovelace card.
Attaching image of all the configs in case I’ve messed something up.
Anyone have any ideas? This is pretty terrible… see for yourself!
I have an identical switch in the living room which migrated just fine and is working as expected. One difference: this crazy one is a 3-way (dumb) and the living room is a single switch.
This is interesting, though (I think). I just tried turning “Smart Bulb Mode” (parameter 52) ON (it was and has been off) and now when I turn the light on it only flashes once quickly and then turns off, AND in Home Assistant the UI switch turns off, too!
I’ve disabled all the Node-RED flows, so I don’t think that’s a part of the problem.
I think I’d try to isolate the problem. Either something went sideways with the switch as a result of the firmware upgrade or something went sideways as a result of the firmware upgrade AND its interaction with HA.
I’d remove the switch from HA and factory reset it. Reset the neutral type and switch type parameters and test. If it continues to act the same way, I’d probably re-flash. If it works fine, then the issue is with the HA interaction so you can then look further in that direction.
No worries. I misunderstood that. But the concept is the same. You want to see if the switch is acting up independently or if the hub is factoring into the issue. It’s just a simple way to let you know in which direction to look.
The red, green, blue is the switch rebooting. Hard to tell what is causing it at this point. Since the switch was working fine and all you did was make some changes within HA, I am wondering if maybe some changes were made to the switch to cause it to reboot, although it’s hard to imagine what those might be. While a failed switch is a possibility, it is not likely that the failure occurred just as you made some changes within HA, so I am not thinking that is it.
At this point, I would factory reset the switch. If your line and load is in the same box, wire it as a two-way first to see how the switch behaves. If your line and load are in different boxes it’s a little tougher but you can try that as well. The default settings should be neutral, two-way. If you have to, set the three-way settings via the switch as opposed to adding back to HA at this point.
