Z-wave stopped working

After a upgrade (2 or 3 versions ago). Z-wave stopped working. I have not done any changes to the config.

Here is the z-Wave config I have.

# Z-wave
  usb_path: /dev/ttyACM0

Any help on how to tackle this challenge is much appreciated


What errors are you getting when you start Home Assistant?

Dont know where I should look for the log

But this shows up on my “dashboard”

Ah you found it. Click that error for more details.

Are you running Home Assistant on a raspberry pi? If so, the location of USB devices changes from time to time so your Z-Wave stick is probably no longer at /dev/ttyACM0. Follow this tutorial to get a static location that your Z-Wave stick can always be found at.

Yes its a raspberry pi

thank you. ill try that :slight_smile:
