Red Series VZW31-SN Disconnect Every Few Days

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 run because they are stopping at this particular switch.

Annoying workaround: If I go to the switch an push a button on it, it seems to wake it up, and it will resume connection to HomeAssistant/zwave.

I have a Aeotec Zwave Z-Stick 7. Recently I updated the Z-Stick 7 firmware to V7.21.6 in hopes this would improve but the issue still occurs. The firmware on the VZW31-SN is 1.02. I see there is beta version 1.04 available but I’m hesitant to test that.

Do you have other devices in the Z-Wave mesh or is it only VZW31s? The reason I ask is that there’s a known firmware issue with 700 series Z-Wave adapters where they have a bunch of mesh stability issues. I think upgrading to 800 series is the only way to fix that if that’s the problem you are running into. And if you do do that, the Nabu Casa made ZWA-2 adapter works exceptionally well.

Ok. I didn’t realize there were ongoing issues with the 700 series z-wave adapters. Yes. I do have a variety of z-wave devices on the network. Like zooz power switches, locks, etc… Thank you for pointing that out. I could try ordering the Nabu Casa made ZWA-2 adapter although not sure if I can get it in Canada.

Are you only seeing problems with the Inovelli devices? And all of the other ones are fine? Any other 800 series devices on your network?

Yes. Only problems with VZW31-SN. Other devices have not had issues with connection. I don’t think I have any 800 series devices. Just 700 series or older. I just ordered the Nabu Casa made ZWA-2 adapter so hopefully that works. I’m also upgrading the firmware to 1.04 beta to see if that helps.

Fingers crossed that it fixes it for you. I’ve personally not had any issues since switching to the Nabu Casa adapter myself. Though I used to have issues with all sorts of devices freezing up like you described, not just the Inovelli ones.

Unfortunately after upgrading to the Nabu Casa made ZWA-2 adapter the issue persists. Also upgrading to the 1.04 beta firmware did not help.

@EricM_Inovelli might have to look at this.
