Getting MySensors MQTT Gateway working on OpenHAB 2.2 (Stable)

[martim]

@fredswed Hi, I really like MQTT so that is my prefered method. But I can try first on ethernet and then step back. I will try in the weekend since I am now a week away :( I used the latest version of the binding and also for MQTT.

I spend again a few hours. I really want to get it to work with MQTT as I have my complete system based on it. But Apparently, the binding does not work and also the log does not say much. Only those errors:

@martim Don't use the binding! Use plain MQTT.

I'd love to have a simple working binding but it isn't there yet. Use plain mqtt elements and it'll work great.

The new mqtt binding works. I don't like the mechanism needed to configure the broker, and then each thing, but works, and it is in fact more integrated with openhab than ever.

If you have any questions do not hesitate to contact me.

The new MQTT binding requires parts of the new automation engine. This is missing from your system for some reason. Should be automatically installed when MQTT or the MySensors binding are installed.

I'd love to have a simple working binding but it isn't there yet. Use plain mqtt elements and it'll work great.

This statement is not correct. The OH 2.4 release officially supports the new binding and if any errors are reported, they are getting fixed. The new binding allows Paper UI and textual configuration so there is no reason to start with mqtt1 nowadays.

Cheers,
David

[Guillermo Schimmel]

@davidgraeff Yes David, you are correct. The new binding works. I'm in fact using it and with the corresponding changes on the items files its ok.

I would love some kind of auto discovery though. In order to create each thing you have to manually enter the topic (which on mysensors is very complex)

Anyways, I will try to edit previous message which is in fact wrong.

[Guillermo Schimmel]

@masmat Yes!!!! Thank you man. I found 2.4.0 thanks to your message and now it's working!

Love

Hi all, I am a Newbie an trying to get OH2.4 to work with MySensors nodes.
I have a MYS Mqtt ethernet GW up&running (seems to work, can talk to other sensors)
Now I can't get MQTT thing/broker/binding to work in OH2.4. I first tries the manual above, then I read that Musquitto is not needed any more....right??
I have to use MQTT 2.4 Ting binding and MQTT broker right? -> I have installed this and have MQTT broker running on localhost (online) (no channels addes in MQTT broker)
I have added in Things: MysensorsMQTT gateway: broker name: "MQTT Broker" and 'startup check' and 'sanity check' ON
Then I checked from the CLI the file "org.eclipse.smarthome.mqtt.cfg" ->there was still the musquitto entries I made... Also in mqtt-eventbus.cfg was still broker=musquitto. What do I do with this??
In OH log I get errors:

****2019-02-10 21:52:35.274 [me.event.ThingUpdatedEvent] - Thing 'mysensors:bridge-mqtt:9954d183' has been updated.

---*

Next problem:
I installed the MySensors Ethernet gateway thing in OH, configged it with IP of Arduino running the Mys GW. -> This Thing will NOT come 'online'. I can Ping the GW board, all looks OK in GW log:

How do I proceed? Ive tried to find more posts on getting MySensors to work under OH24 but I think it is sooo simple that nobody has any problems to post....right?!
Hope you guys can get this Newbie back on track.... thx a lot!

Hi @rene-mullie,

Seems like the mysensors binding mqtt gw doesnt play nice with the mosquitto broker. You can try running the embedded broker of openhab (paperUi->addons->misc->embedded broker i beleive). Dont forget to configure it under services->misc (not shure since im on my phone right now). And connect your mqtt gateway to this broker. I was not succesful in this because i need the embedded broker on port 1884 since i allready have mosquitto on port 1883 for other stuff. And i <think> mysensors mqtt gateway doesnt want to connect to 1884 but 1883. But you can give it a try. If you have ethernet gateway going and dont have plans to use different controllers (for example to do FOTA updates) i would stick to the ethernet gw for now. Greets

[Rene Mullie]

I have configged the embedded broker in right way, broker is online on localhost.
I tried to connect Mys mqtt gateway to Embedded mqtt broker in paper UI:

Broker Name
MQTT Broker (-> not sure about this name....??)
name of the MQTT broker as defined in the org.eclipse.smarthome.mqtt.cfg file``` (-> if I check this cfg file there is NOTHING about the embedded broker, only old Musquitto stuf...)

All is on default port 1883 on both sides...

I get fault in OH log file:

2019-02-10 23:40:56.626 [ERROR] [al.protocol.ip.MySensorsIpConnection] - Failed connecting to bridge...next retry in 10 seconds (Retry No.:15)

[waspie]

broker name is "embedded-mqtt-broker"

[Rene Mullie]

@waspie tried that, still same errors...
What should be the entries in the org.eclipse.smarthome.mqtt.cfg file ?

[waspie]

@rene-mullie delete it

[jimmy loyens]

@rene-mullie if im not mistaken that file is to configure mqtt v1 and your using mqtt v2

[Rene Mullie]

Thx4 your support! I gave up on fixing the old install and started over with brand new install of OH2.4: All was up&running in 45mins!! MQTT2.4 with embedded broker works like a charm. On top the Mysensors MQTT GW Ting was online with 1-click! All my MYsensor nodes where recognized immediately! What a relief!
Hope someone will update Mysensors docu so others will be spared the pain...
