Z-Wave does not start

hello and happy new year to all

I am new with HA and with English I am French !
I wanted to start by including z-wave because I have quite a lot of equipment to this standard…
I have a flash drive aeotec Z-Stick Gen5 on the usb port /dev/ttyAMA0
But I can’t start the z-wave network

HA 2020.12.7
journal OWZ “Detail, contrlr, Notification: DriverFailed”
configuration.yaml :


  • platform: google_translate

group: !include groups.yaml
automation: !include automations.yaml
script: !include scripts.yaml
scene: !include scenes.yamll"

I must have missed something like all the beginners but I don’t see, can you help me ?


We need more Infos from the OpenZWave Config

I don’t see any Z-Wave config in your YAML (network key is if you want to control secure devices like a lock, and this is not my real network key, it was changed to protect the innocent):

  usb_path: /dev/ttyACM0
  device_config: !include zwave_device_config.yaml
  network_key: "0x11, 0x8A, 0xCA, 0xA8, 0xD6, 0x00, 0x76, 0x5C, 0x76, 0xBC, 0xE6, 0xCE, 0x4B, 0xB5, 0x22, 0x3D"

how, where to find the network key ?
thank you very much

@Wanfr plz read first this:

and this:

You can generate it from a shell prompt on the HA system:

cat /dev/urandom | tr -dc '0-9A-F' | fold -w 32 | head -n 1 | sed -e 's/\(..\)/0x\1, /g' -e 's/, $//'
