Does this mean that I was able to connect? However, I still have no reaction in the "devices" tab, and the status in the hardware "setup"

@sundberg84
ie the solution is to open the serial port on the Raspberry Pi side yes?

Hello, I have a problem, I tried to connect raspberry pi with arduino in the domoticz application, I put the project on the arduino which would send information about the motion sensor, when I try to connect the arduino with domoticz after the USB gateway mysensor error pops up "
Error: Serial Port closed ", does anyone know a solution to the problem? Please help
