Fresh installed ZWave 1.4 not working - what do I miss?

Tags: #<Tag:0x00007f3268ab8b90>

Hello everyone,

I installed Home Assistant on a fresh SD card (standard procedure for dummies like myself

My hardware:

Raspberry Pi 3 Model B V1.2
Razberry Z-Wave Plus 5th gen chip ZM5202

I edited /mnt/boot/config.txt to contain both lines:


In my configuration.yaml:

  usb_path: /dev/ttyAMA0

OpenZwave.log says:

What is my mistake? What do I miss?

I would really appreciate any hints!!!


same problem here with the same Hardware.

i tried HO last year and i had the same problems but i could be solved like in this link:

but with this version i didn’t solve the problem.

any ideas?


I have the same issue. Tried


But I only get DriverFailed, as above.

I’m receiving exact the same error after updating Home Assistant OS from 5.9 to 5.10.
My setup is similar to yours:

  • Raspi 3 Model B+
  • Razberry GPIO Board

Obviously the hassos update has reset my config.txt file! So I attached the SD Card to my windows PC and added (again) the following lines to the end of the file:

# Disable WiFi

# Disable Bluetooth

# razberry

But it doesn’t help even after restarting the host.

Please Help!
