Getting MySensors MQTT Gateway working on OpenHAB 2.2 (Stable)

[TimO]

@masmat please check your MQTT configuration. You're receiving an exception because it's trying to set "1883.0" for the value port.

[MasMat]

@timo I did. I can't figure out where it's finding that .0 it adds to the 1883 port I have in the cfg-file

[CrankyCoder]

How close is this for 2.3? Worth a try? or should I hold? Thanks for the work so far on it!

[jogant]

@crankycoder Unfortunately there are still issues with the mqtt implementation. I reverted back to 2.2 yesterday as all my fiddling didn't help.

[CrankyCoder]

my setup is still just using the direct mqtt subscription so i will hold off.

is there any discovery working (in 2.2 that is) how about once you configure the things. do you get all the properties of that item from when it presents?

[jogant]

@crankycoder in 2.2 with appropriate binding mysensors is working pretty well. All variables are presented with mysensors lib 2.2.
I only updated openhab to 2.3 as this release was presented on my debian system. But I didn't get 2.3 working with mysensors mqtt.

[CrankyCoder]

I did an upgrade the other week from 1.8 to 2.2. Then right about the time I had some stuff working 2.3 came out. So I figured since I have to do all the learning curve anyways I might as well stick with 2.3. The variables being presented in mysensors would be HUGE for me. But hopefully it's not too far out.

[jogant]

@TimO : are there any news concerning compatibility to version 2.3?
Thanks for your work!

[TimO]

@jogant There already is a working version (2.4 SNAPSHOT) available on the marketplace and on my server. Please let me know if you expierence any problems.

[jogant]

@timo unfortunately this also does not work for me. I followed your manual very well but I always get errors. It starts after installing feature:install esh-io-transport-mqtt and mysensors binding:

and reconection starts every 10 seconds.
It must be interference with mqtt1 bindung that I use for eventbus.
The mqtt-bridge remains Offline.
What is wrong?

[TimO]

@jogant Indeed this looks like an error in your configuration. I suspect the MQTT configuration. Did you change the MQTT configuration according my posting above? I've also added a text to the Wiki. The name and content of the MQTT configuration differs between OpenHAB 2.2 and 2.3.

[jogant]

@timo with 2.2 I had two configurations which were very similar.
I have one mosquitto mqtt broker on localhost, version 1.5.
The mqtt1 binding is for my mqtt-eventbus connection is called mosquitto and the config file (mqtt.cfg) is as follows:

mosquitto.url=tcp://192.168.96.8:1883
mosquitto.retain=false
mosquitto.clientId=openhab
mosquitto.user=user
mosquitto.pwd=pwd

With OH2.2 this configuration works. It also works with 2.3 as I can see all openhab events on my mosquitto.
My mysonsors binding is configured by org.eclipse.smarthome.mqttbroker.cfg config file which looks as follows:

name=mosquittomys
host=192.168.96.8
port=1883
retain=false
username=username
password=password
clientId=openhabMys

I also tried without authentication and also without clientId, all to no succuess.
I cleaned /var/lib/openhab2/cache/ folder and /var/lib/openhab2/tmp/ folder.
I looked at /var/lib/openhab2/config folder for resulting runtime configuration, but all looks fine. Do you have any further idea?

[jogant]

@timo I found the fault in my configuration: it was the missing secure=false config flag in the org.eclipse.smarthome.mqttbroker.cfg config file. I have no idea what happens when the flag is missing but without it one doesn't achieve a valid connection.

name=mosquittomys
host=192.168.96.8
port=1883
secure=false  <-- important !

So now I have a working 2.3 installation! Thanks alot for your support.

[TimO]

@jogant Good catch! I'm glad it's working now! :-)

[MasMat]

I'm still unsuccesful.
Do I need to reinstall all the files as well? I didn't find a new set of instructions.

In my /etc/openhab2/services-folder I have:
mqtt-eventbus.cfg containing just

broker=mosquitto

and org.eclipse.smarthome.mqttbroker.cfg:

name=mosquitto
host=127.0.0.1
secure=false
port=1883
secure=false
username=XXXX
password=YYYYY
retain=false
clientId=openhabMys

openhab.log everything mysensors related:

Anyone spot what's still wrong?

P.S. I remember seeing someone got MyS gateway to log to a different file. Does anyone know how to implement that in the ./configure -command? Or how can I do that?

[jogant]

@masmat two things come to my mind: I have two different broker-names for eventbus connection and mysensors connection. For eventbus binding you need classic mqtt1 binding with its own configuration like this:

mosquitto.url=tcp://127.0.0.1:1883
mosquitto.retain=false
mosquitto.clientId=openhab
mosquitto.user=user
mosquitto.pwd=pwd

And second: can you show your mysensors bridge configuration? Not shure but debug log looks like an ethernet bridge and not a mqtt bridge.

[MasMat]

Not sure how to answer some of your questions...but here goes.
configuration:

sudo ./configure --my-transport=nrf24 --my-rf24-irq-pin=15 --my-signing-debug --my-signing=password --my-signing-password=XXXXXXXX --my-gateway=mqtt --my-controller-ip-address=127.0.0.1 --my-mqtt-user=YYYY --my-mqtt-password=ZZZZZ --my-mqtt-publish-topic-prefix=mysensors-out --my-mqtt-subscribe-topic-prefix=mysensors-in --my-mqtt-client-id=mygateway1 --my-leds-err-pin=12 --my-leds-rx-pin=16 --my-leds-tx-pin=18

I'm not sure what "eventbus"-binding is. Something I need to install in Paper UI?
Is the configuration file mqtt-eventbus.cfg or something else? Should I try to install it? I have not installed the MQTT binding in OpenHab because at least originally the instructions said not to.

[jogant]

@masmat I just wanted to understand your configuration. So I read through whole thread and saw your problems began with upgrade to OH2.3.
I mentioned eventbus as you wrote something about eventbus.cfg.
You need eventbus only if you want to send all oh events to mqtt broker.
I wanted to see your mqtt bridge configuration. You can either configure dynamicly via paper ui or you set it up via things file. The later is what I did. So here is my things file with bridge configuration.

Bridge mysensors:bridge-mqtt:gateway [  brokerName="mosquittomys",
                                        topicPublish="mysensors1/in",
                                        topicSubscribe="mysensors1/out",
                                        startupCheckEnabled=true ] {

}

Here the brokername has to be the same as in mqttbroker.cfg. Fix topic names to match your mysensors gateway.
Hope this is of any help.

This post is deleted!

[MasMat]

@jogant Finally had time to double check this:
Paper UI:

Broker Name 
mosquitto
Subscription Topic 
mygateway1-out
Publish Topic 
mygateway1-in
Send Delay 100
Startup check enabled
Metric answer enabled
Network sanity check enabled
Interval to launch network sanity check 3
Attempts before disconnecting the bridge 3
Heartbeat disabled
Attempts before disconnecting nodes 10

EDIT: I noticed I have different topics in MQTT, corrected AND I did:

cd /usr/share/openhab2/addons/
wget http://www.oberfoell.com/openhab2/org.openhab.binding.mysensors-2.4.0-SNAPSHOT.jar   <== THIS probably  fixed it!
chown for the same file

rm org.openhab.binding.mysensors-2.3.0-SNAPSHOT.jar

Now my MQTT Gw is ONLINE, in Paper UI I just selected the bridge for every individual Thing and now it works.
Hope this helps people strugling with this.
