OpenHAB 2.3 and MQTT

  • Hi All,

    I am very new to openHAB and I have a lot of problems installing/configuring openHAB 2.3 so that mysensors are working. Does anyone have a guidline how to install this?

    It seems that MQTT connect well but I got an error which I do not understand. I am already busy with it for days but I do not get it working. Unfortunatly I am not able to find openHAB 2.2 img so that I can install this on my PI.

    Anyone willing to help me?

    @martim I'm sorry myFriend. I've tried OpenHaB a couple of years ago. But in those days I couldn't get it to work. To complicated for me. That's why I've switched to Domoticz. That does what I need. You could give that - or another controller - a try. OpenHAB is overly complicated if you ask me.

  • I'm using mysensors with openhab and mqtt and works great.

    Check your config files!

    Let's take a look at your mqtt.cfg.

    Which broker are you using? I'm on mosquitto.

    Could you check here? I am really getting frustrated by the OpenHAB 🙂

  • @martim I would recommend you to use plain mqtt.

    Don't use the binding or the bridge stuff. Once you have the mysensors-mqtt, use plain mqtt items on your openhab config and it will work great.

    I already have several sensors this way.

    Perhaps after openhab 2.4 I will play a little with the binding and then I could be more useful to you.

  • Just for you to know, I just updated to 2.4 and can confirm that with the new mqtt binding I can connect with mysensors.

    You have to create the MQTT Broker think via the web ui and then each thing, finally you have to modify your items, like this:

    //Contact GaragePorton "Portón Garage [%s]" <garagedoor> { mqtt="<[mosquitto:mygateway1-out/11/3/1/0/16:state:default]" }
    //Contact GaragePuerta "Puerta Garage [%s]" <door>       { mqtt="<[mosquitto:mygateway1-out/11/4/1/0/16:state:default]" }
    Contact GaragePorton "Portón Garage [%s]" <garagedoor> { channel="mqtt:topic:efe295fe:porton_garage" }
    Contact GaragePuerta "Puerta Garage [%s]" <door>       { channel="mqtt:topic:efe295fe:puerta_garage" }
