Home Assistant with the Z-wave JS 2MQTT


  • Home Assistant
  • Select Z-wave JS on the sidebar
  • Select the Control Panel if you’re not already in it
  • Select the device you want to update by clicking on the down arrow on the left side of the selected device
  • Click on the Advanced button on the right
  • Under the Firmware update click Begin
  • Leave the target 0 (Z-wave chip)
  • Select the OTA file from your drive
  • Confirm to start the update by clicking OK
  • Wait until it is finished


When the update is finished, the device will be marked dead. The Home Assistant will need to do the re-interview of the device (node). If this doesn’t start automatically after some time, you can do it manually by clicking the Interview in the Advanced window of the selected device.


If none of this has any effect and the device is still marked dead, you can try to re-include the device.
