I run home assistant in a docker envirionment, same for z-wave JS UI. I use since a while ZWA-2 (FW 1.2) and I did run into issues to access my z-wave devices.
I tried to re-interview / re-build routes.
Some devices stay on protocol / node-info and don’t proceed. Restarting ZWA-2 is helping to complete the interview process. But for many (shelly / fibaro) devices I get unknow manufacturer ID and product ID.
The inclusion of new devices does also not work. They are simply not recognized (all security layers).
I connected the stick today via a powered USB Hub, but it also does not help.
Any idea where to look for problems? I didn’t see anything specific in log files.
A single device that has communication problem may break the entire zwave network.
In zwavjsui or HA you can look at Statistics for device. This will show communication statistics per device.
Start by checking zwa-2 for high dropped TX or high Dropped RX. If there is a problem it will be obvious. If zwa2 is normal probably all is OK. If it is bad you must check each device to find which is causing the problem.
