Hello all!
I know this question is considered solved, but the link:
Pi 4 setup with Razberry V2 (Solved) - #6 by Jeff_G from markus85 refers to the integration of a zwave USB stick and not an EnOceanPi for the GPIO. There are two small differences to note with USB and zwave.
As already described
After the HA installtion, pull the SSD card out of the Raspberry and put it into the PC.
open config.txt
add the following lines:
dtoverlay=disable-bt
enable_uart=1
Power on RPi without EnoceanPi and finish installtion of HA. Shutdown HA, switch off the Pi and plug the EnoceanPi to the GPIO.
Install the addon “File Editor” under Supervisor. Open the configuration.yaml in the path /config. Add the following lines:
enocean:
device: /dev/ttyS0
Here you have to enter enocean instead of zwave and instead of usb_path: /dev/ttyS0 you have to enter device:. The two spaces in front of device are also necessary. Then I restarted HA.
Now in HA under Settings → Devices & Services → Integrations → EnOcean → Add entry.
You will be asked for the USB path, here enter: /dev/ttyAMA0
Now no error should be displayed in the Integrations window for EnOcean.
