Hello all,
I’m looking for ideas on troubleshooting a Z-wave issue that has cropped up on my system. It has been stable for some months but after a power outage 3 days ago things aren’t stable with Z-wavel. All the other integrations seem to be fine.
Configuration:
Z-wave controller is a HomeSeer Z-NET which is a Raspberry Pi 3B with a Express Controls EZZee HAT installed. I belive this board is based on the 500 series chip. It’s been working fine for some months, with about 70 Z-wave devices connected. Z-Wave JS UI Addon is installed on a Supervised HASS install with TCP connection configured to the Z-NET. Z-Wave JS Integration points to the Addon instance.
If I restart the Z-Wave JS UI, everything will work for 10 minutes or so, then things just stop reporting. Watching the logs at debug level the normal Z-wave traffic stops and the logs start repeating this:
2023-02-03 16:06:18.283 INFO APP: GET /health/zwave 200 1.165 ms - 2005
2023-02-03 16:08:18.291 INFO APP: GET /health/zwave 200 1.167 ms - 2005

2023-02-03 16:18:18.337 INFO APP: GET /health/zwave 200 1.757 ms - 2005
2023-02-03 16:20:18.345 INFO APP: GET /health/zwave 200 1.196 ms - 2005
It’s like the TCP connection to the Z-NET has gone silent. A restart of the Addon will repeat the process. During the health URLs above, any interacting with lights or devices will generate a ZW0202 error after a few seconds.
ERROR Z-WAVE-SERVER: Failed to send the message after 3 attempts (ZW0202)
At first I thought maybe something happened to the Z-NET, and I have a spare, but to separate software problem from hardware problem, I shut down the Z-Wave JS UI addon and fired up my previous software connected to this device (HomeSeer). I enabled Z-Wave and turned on logging and everything worked fine. I watched it for an hour and a half and everything was still working and controllable. I shut that down and restored a Home Assistant backup from prior to the power outage, 5 days ago. Still had the same symptoms. Everything works fine for the first few minutes, then Z-wave traffic goes silent and stops working.
Not sure where to go from here. Any advice is appreciated.
