Domoticz

My Z-wave devices have been working fine until I just updated to 2023.2 build15555 and now none of them work and the Aeon Z-wave stick is no longer recognised. It is plugged into one of the usb2 ports on a PI4 same as it always has.

It is still listed in the hardware but it says tyoe - unknown

Any Ideas?

If you are using OpenZwave then indeed Zwave will not work as OpenZwave has been deprecated in 2023.2 beta. The forum is full with warnings for this.

So return to the previous version you used before or migrate to Zwave-JS-UI (including installing MQTT broker and Zwave-JS-UI, possibly with Docker).
For returning back to the previous Domoticz version see wiki https://www.domoticz.com/wiki/Raspberry ... eta_update
You will lose some data.
To migrate to Zwave-JS-UI see wiki https://www.domoticz.com/wiki/Zwave-JS-UI

So by the sound of it I will have to migrate to Zwave-JS-UI sometime or forever stay on an older version of domoticz with it's ever present "there is a new version" box.
Sounds like I will have to migrate........

You can switch off the new version check in menu setup settings. Also wise to stay on stable instead of beta. 2023.2 stable is the last version with OpenZwave.
