Getting MySensors MQTT Gateway working on OpenHAB 2.2 (Stable)

[andre_m87]

Hey,

same Problem here. After upgrading to OpenHAB 2.3 i receive the same errors in my /var/log/openhab2/openhab.log

2018-05-31 16:28:42.776 [ERROR] [rotocol.mqtt.MySensorsMqttConnection] - No connection to broker: mosquitto
2018-05-31 16:28:42.918 [ERROR] [rotocol.mqtt.MySensorsMqttConnection] - Failed connecting to bridge...next retry in 10 seconds (Retry No.:0)

@andre_m87 & @MasMat : I have the same problem here. Looks like a change in the OpenHAB MQTT implementation.
I'm working on it.

[TimO]

@andre_m87 & @MasMat : I found a solution and indeed the MQTT implementation in OH2 (ESH) changed. This was a hard nut to crack, so it took me a while.

Here are the steps you need to do:

1. Rename: org.eclipse.smarthome.mqtt.cfg to org.eclipse.smarthome.mqttbroker.cfg
2. Change the content to:

name=mosquitto
host=192.168.2.3
secure=false
port=1883
username=USERNAME
password=PASSWORD
retain=false

If you're using a secure connection (SSL): change secure to true and use the correct port.

Another intersting feature in OpenHAB 2.3 is the embedded broker, so there is no need to have a separate MQTT server up and running.

@timo unfortunately this solution doesn't work for me.
After update oh to version 2.3 I don't get mqtt to work. Prior I used mqtt for mysensors and for eventbus. I configured two broker connections and set up a mysensors-mqtt-bridge via things-file. In the broker all events from openhab arrived and all mysensors-messages arrived in openhab.
After update mysensors doesn't work at all, allthough I followed your instructions. If I setup mqtt1 binding I can see eventbus messages in mqtt broker but my mysensors-mqtt-gateway remains initializing.

What I'm doing wrong?

[TimO]

@jogant Yeah. :-( There are still some problems with 2.3 to fix. The binding works fine within the development IDE, but only there. I'm still looking into it.

[MasMat]

Did that, MQTT bridge stuck at "initializing". Not the full answer yet, but thanks @timo for your effort!

[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! :-)
