Thank you for your answer!!
I have copied the 3 files in my custom_components folder, a new folder “serial”.
# Example configuration.yaml entry
- platform: serial
in the configuration.yaml and restart HA.
After I send something via UART, I get the following Log:
Integration: serial (documentation, issues)
First occurred: 01:11:55 (1 occurrences)
Last logged: 01:11:55
Error while reading serial device /dev/serial0: device reports readiness to read but returned no data (device disconnected or multiple access on port?)
Traceback (most recent call last):

serial.serialutil.SerialException: device reports readiness to read but returned no data (device disconnected or multiple access on port?)
I found out that the port is already used by nodered.
(My “Integration” is currently in nodered and this used the port).
When I stop nodered (also don’t start with boot), the error ’ device reports readiness to read but returned no data’ isn’t there anymore.
Now I try to find a serial-message I send, but I can’t find it…
(I changed the Baudrate in the sensor.py and the rest of the settings should work for me.)
I think the line CONF_SERIAL_PORT = “serial_port” says, that the serial_port: /dev/serial0 from the configuration.yaml should be used - am I correct?
Could you help me again?
