OpenHAB Mysensors binding 2.4: cant get mqtt gateway online

[TimO]

@guillermo-schimmel You've mixed up attributes from the MySensors binding and the MQTT binding in the bridge definition. brokerName, topicSubscribe and so on are attributes from the MySensors binding. But this won't do any harm.

How is the MySensors gateway defined?

[Guillermo Schimmel]

@timo Mysensors gateway is defined via Paper UI:

Thanks, cleaned up config file:

Restarted all, still all working fine.

@guillermo-schimmel OK, next question: how did you define the system broker named mosquitto? Because that's the one the MySensors binding seems to use. In a service (cfg) file? I've had no success defining one and maybe that's the key.

[Guillermo Schimmel]

@timo Via files. It was the old broker I was using with the 1.x mqtt binding.

[jimmy loyens]

If I can do anything to help please let me know

[MasMat]

I had a working mqtt-gw but the lastest update (using openhabian so updates every time with system) screwed up my system. I have reloaded the binding and also rebuilt the gw (Rpi) to get newest MySensors version.
Haven't had time to troubleshoot yet.
Binding behind after latest update?

[jimmy loyens]

@masmat Hi, I think @TimO is looking into it. Ethernet and serial gateway work as expected with mysensors binding. My guess it has something to do with new MQTT-binding.

same here, updated from 2.4.0 to 2.5.0 snapshot and it died.

I was using an MQTT broker solely configured via paperui and it worked like a dream. 2.5.0 - not so much.

I don't know if this is of any use or not but many hours later in my openhab.log I received this:

I've still found no solution but if I use the new embedded broker in OpenHAB2 and connect the the MySensors MQTT gateway to that broker everything works fine.
But I'd no success in connecting the MySensors MQTT gateway to a working MQTT-broker (MQTT2) or in creating a SystemBroker (MQTT2).

So for those of you that are willing to use the embeeded broker, this works fine with the MySensors MQTT gateway.
Just use embedded-mqtt-broker as broker name in the MQTT gateway configuration.

[jimmy loyens]

@timo thanks for the update. I will try it as soon as i get the chance. Thanks

[waspie]

@timo
works for me, will try it out.

also, i got it working another way. tested it on clean installs of 2.4.0 vs 2.5.0-1512
back to the config file org.eclipse.smarthome.mqttbroker.cfg
not sure why it didn't work in 2.5.0 the first time. i'm starting to think it was leftover in the userdata folder which is why i thought it was no longer necessary in the services directory

but, if i can skip it altogether and user the system broker then i'm just as happy with that. one less thing.

BTW, for anyone who happens along this thread in the future: literally the only two bindings you need to install in 2.4.0-2.5.0 is the serial binding and the mqtt (2.x) binding. then drop the mysensors binding in. that's it. it's so much easier now.

[jimmy loyens]

@timo I connected to the embedded broker over port 1884
. But i cant seem to discover my nodes. This is my broker thing:

mqtt:broker:embedded-mqtt-broker[host="192.168.1.2", 
                                        port="1884",
                                        qos=1, 
                                        clientID="gateway1", 
                                        reconnectTime=20000, 
                                        keepAlive=60000, 
                                        secure=false, 
                                        username="xxx", 
                                        password="yyy"]

This is my mqtt-bridge thing:

Bridge mysensors:bridge-mqtt:mygateway [brokerName="embedded-mqtt-broker",
                                        port="1884",
                                        topicPublish="mygateway1-in",
                                        topicSubscribe="mygateway1-out",
                                        startupCheckEnabled=false]{
}

Its weird because i can see the messages from the nodes coming in in the log vieuwer (mysensors binding is in TRACE).

And can you point me to the docs on how to setup the binding ? I found them before but cant seem to find them anymore.

Thanks

@jimmy-loyens Could you please check if the embedded-mqtt-broker thing is online? I suppose not. If the embedded broker addon (misc) is installed OpenHAB automatically discovers this embedded broker, just add that thing from inbox.
Now connect your MySensors MQTT gateway (hardware) to the IP and Port of the embedded-broker. After that your MySensors-bridge configuration should work. The port configuration at this point is not needed, but should do no harm, it'll be ignored.

Documentation for the binding: https://github.com/tobof/openhab2-addons/wiki

is there any reason to prefer MQTT over Ethernet? If getting MQTT to work is this much of a pain why are we bothering?
Maybe I'm missing something

[Guillermo Schimmel]

@waspie it's not so much pain. I have it working fine. Setup could be simpler, but it works.

The main advantage, at least for me, is unifying all over mqtt. I have mysensors, but also some server monitoring scripts, a vacuum cleaner control, etc.

It's really nice to have a single layer of abstraction between openhab and everything else.

[TimO]

@waspie you're able to use more than one controller with the MQTT gateway. So while using Openhab for automation you may use My Controller for wireless node updates / firmware uploads. That is not yet possible with the binding.

[waspie]

I'm still planning to use MQTT as I have it tied to about 20 esp8266s around the house so I would never abandon it :)

One problem I'm having now that I switched over to the embedded broker is the LWT doesn't seem to work right.

I have a module in each car that when it disconnects send a LWT of off so I know to automatically close garage doors. Using the embedded broker has broken this for some reason??? So I start to think why not just use ethernet for mysensors. Fix one problem create 10 more :\

[TimO]

@waspie Well, I do use an MySensors ethernet gateway with the MySensors binding which works fine.
In addition to that I have MQTT devices, for example may heating unit (ebusd) which I connect via Mosquitto and the generic MQTT binding to OpenHAB. MySensors is not involved here.
My advice: use the ethernet gateway with the MySensors binding and keep Mosquitto for the rest. There were some changes in the MQTT implementation of Openhab in 2.4 which lead to some problems, like the one in this thread and I've found some more, while trying to adapt the new configuration and I'm sure there will be some changes to that in the next release. I'm currently using two Openhab instances (2.3 and 2.4) in parallel till all problems are solved.
