Hi, I’m having issues still with our VZW31-SN Red Series Switches. There are about 35 switches. They will work fine for 3-5 days, then suddenly one or two switches (seems to be random) will show as disconnected (Dead) in Home Assistant/zwave JS UI and in turn I notice zwave automations have not ru…

I’m up to 15 days now with firmware 2.0.0 and no switches have gone dead. Seems to have for sure fixed the issue for me.

@Bry , good thought, but I think that only affects 2x, 3x and 4x presses. I had it on 300mS, but I just tried it with no delay and it still outputs the paddle presses (and is more responsive so I think I’ll keep it that way except on the dimmers where I want to recognize multiple presses).

[image] zowzer: However it’s not all good news as one of my dimmers stopped sending ZWave notifications when the paddle or config button was pressed On the ones you are having difficulty on can you do this? reboot the switch by pulling the air gap out for a couple of seconds In zwave js do …

Did that. I do have that association. Will let you know if I see the problem again and whether those steps restore it.

The new firmware seems to have solved the disconnect problems for me. I haven’t had any issues since the initial hiccup after installing the firmware. I still find that zwave isn’t 100% reliable with Home Assistant scenes. Would love to get that sorted, but at least I don’t have to worry about the …

The disconnects seem to be solved with the firmware, HOWEVER there is an annoying bug where the transition durations are being modded with 25, so any transition duration larger than 24 seconds ends up being less than 25 seconds. I don’t know if this bug is new in this firmware, but the problem doesn…

I’ll look into it. Can you give me some examples of how you are doing it? If you go into the zwave js gui and use switch multi level set with a duration it happens there?

Sure, here are a few examples done from Z-Wave JS UI: A 25 second transition. It takes 26 seconds. A 26 second transition. It takes 0.5 seconds. A 45 second transition. It takes 20 seconds. A Leviton dimmer with a 45 second transition. It takes 45 seconds. 25 second transition … 2026-04-07 19:13…

Thanks, I have logged this issue and the engineer is working to fix it.

@EricM_Inovelli Hi Eric,I recently updated my devices to FW: v2.1.0 SDK: v7.24.2 using the file from the Red-Series/Z-Wave/VZW31-SN-2-1-Switch/Beta/2.01/ directory. Since the update, I have been unable to group my 3-way dimmers. I attempted to roll back to FW: v1.04, but the downgrade failed with …
