    I've also tried adding the user pi to the dialout and tty groups, but still I can't select any port in the arduino ide when mysgw.service and openhab2.service are stopped. It's as if the mysgw.service is creating the ttyUSB0 port (virtually?) :confused:

    I did a ls /dev/tty* and ttyUSB0 had disappeared...so I unplugged the gateway and plugged it back in again (all while mysgw.service is stopped) then another ls /dev/tty* and ttyUSB0 was back. I started the arduino ide and selected ttyUSB0 and in the serial monitor I now have:

      When I restart the mysgw.service and do a ls /dev/tty* the ttyUSB0 is shown in blue as opposed to yellow as seen below.

        @CraigDubya mysgw.service is partly a software gateway. From earlier posts, it seems you also have a hardware gateway (based on an Arduino Nano). Is that correct?

        If so, the two gateways might conflict. Is your intention to run two gateways?

          @mfalkvidd Hi,

          No, my intention is not to run 2 gateways, I did a make on the mysgw.service and changed the port to ttyUSB020 in the config and restarted openhab. I now have communication with the hardware gateway. It seems it's all working properly now, but I'm a bit concerned that I may still have a software gateway running aswell.

            I just rebooted my pi, and whatever I did to get the bridge working has reset, and I'm not getting any node connections anymore :confused:

              If I stop the mysgw.service and restart openhab2.service the gateway works fine. So, the mysgw.service is starting on bootup, how do I remove or disable mysgw.service from bootup?

                @mfalkvidd Sorry, in answer to your earlier question, that's correct... I have an Arduino Nano connected via USB to the raspberry pi as a hardware serial gateway

                  Ah I found it using:

                  sudo systemctl disable mysgw.service
                  

                  Now when I reboot the pi the gateway is working and my sensor node is reporting correctly.

                  Thanks for everyones help, it's been 2 years since I last played with openhab and mysensors, and what I learned back then I had mostly forgotten. Also with the openhab and mysensors updates that have happened in that time it's been a struggle to get back on track :grin:

                      And so here is my serial gateway with 3d printed case:
