ZWave stops frequently

Recently my ZWave frequently stops working and it works again after I reboot my HA.
I am not that technical and would like to know what & where I should look in the log ?

Look for anything about zwave or a zwave device in the logs,

What do you mean by stops?
Does the controller stop working?
Does it show “unavailable” in devices&zervices >> zwave
Do devices just stop responding?

  • What do you mean by stops?
    • I mean that all my 64 ZWave devices are unavailable
  • Does the controller stop working?
    • I guess so but would appreciate how to check exactly.
  • Does it show “unavailable” in devices&zervices >> zwave
    • Yes
  • Do devices just stop responding?
    • Yes
