    @JackRyan You need to set the mosquitto server ip in the openhab.cfg file. I don't know if the instructables guide explain it. Did you do that?
    You can find more about it here:
    http://forum.mysensors.org/topic/303/mqtt-broker-gateway



  • @celonunes Yes I already done it like this right
    mqtt:mymosquitto.url=tcp://192.168.1.13:1883
    mqtt:mymosquitto.clientId=MQTT

    @JackRyan You are running both mosquitto and openhab in the same computer, right? Are you sure 192.168.1.13 is your computer ip? If you are using Windows try to disable the firewall or change the ip in openhab.cfg to 127.0.0.1
