It's been 3 years since I was running with RFlink without any problem.
But since September 2, impossible to communicate with the arduino! (I changed the USB cable and even the arduino in doubt) on a Raspberry 4 with raspbian above
But nothing works!
In domoticz, you can not select a "serial" port when configuring hardware.
