I recently switched from a Raspberry 3 with a Razberry Pro 7 HAT to a Raspberry 4 with a SSD.
After restoring the backup. Z-Wave JS failed to make a connection.
All my other integrations (Hue, MQTT, Tasmota) are functioning.
I checked my Z-wave controller and the Z-Wave network with Z-wave.me on a separate SD-card.
Made a factory reset for all the devices. Except for a Fibaro Smoke Detector, everything worked fine with Z-Wave.me.
What am I missing in Home Assistant ?
The serial device used to connect ZJS to the coordinator will have changed as the RPi4 remaps the console UART to Bluetooth.
You don’t say what radio hardware you are using, but the mention of Z-Wave.me suggests a RaZberry.
These use the main serial port, so likely /dev/ttyAMA0. I used to have a RaZberry, but moved to a Yellow with in-built radios.
I’m using a RaZberry Pro 7. It’s mounted on the GPIO connector.
I will look into the Bluetooth configuration of my RPi4. Thanks.
Thank you very much James.
I had to disable Bluetooth in the config.txt.
Found some instructions how to access this file on a separate Linux PC.
Finally it all worked for me.
Kind regards,
Pieter
