OH3 - MySensors Binding

[fabyte]

Okay, now i tried to configure the MQTT system broker connection and this seems to work.

• I set up the system broker and named it 'mosquitto'.
• in the MySensors MQTT bridge, as before, I used mosquitto as Broker Name. Now the Broker Name could be resolved and the Thing is online.

But
I'm having troubles with the MQTT system broker, it can't connect the broker instance.

Since this seems more a OpenHAB/mosquitto issue I will dig into it myself.

Edit
The MQTT System Broker seems to be a concept from OH2, where a MQTT broker was shipped internally with OpenHAB and it seems to be broken in OH3 (OH Forum).

This leaves me with the following conclusions:

1. The MySensors binding configuration references the MQTT system broker connection
2. With OH3, this MQTT System Broker is not working anymore.

I suppose the correct way of handling this issue is to make the MySensors binding reference a normal MQTT Broker bridge, not a System Broker bridge.
Anyone who knows what changes this would require? My guess is that it should be manageable -> Source Code

[ncollins]

@fabyte this is helpful.

My intuition says the embedded mqtt broker and the generic mqtt binding create the same "mqtt" connection service behind the scenes. I'm guessing the generic mqtt binding isn't registering its service by name, or it's registering it by some other key.

I'd like to get the mysensors addon to work with both mqtt brokers if possible.

[fabyte]

@ncollins Yes, it looks like some resources are blocked or not resolved correctly when using the system broker.
But the system broker functionality comes with the mqtt binding itself. Here is a screen of the settings when I deleted the mqtt binding:

Also I never got the system broker working, even without defining a generic mqtt broker thing.

[fabyte]

After reinstalling the mqtt bindung the MQTT System Broker connection now could be established - strange, that a reinstall was required since I did several OpenHAB system restarts and those didn't fix it.

Well, now the MySensors binding is working with the system broker:

Here's a MySensors temperature item:

To sum up, here's what I did

1. (manually) installed MySensors binding
2. uninstalled mqtt binding
3. installed mqtt binding
4. set up the MQTT system broker connection
   4.1 set Connection Name to systembroker
   4.2 set Broker Host to localhost (it's running on the same device)
   4.3 Show advanced -> set Broker Port to 1883 since it was always using 8883 but I don't use a secure connection
   (4.4 I didn't set a clientid, no user and no password)
5. set up the MySensors MQTT Gateway thing
   5.1 set Broker Name to systembroker

[ncollins]

@fabyte Nice work. I don't use mysensors-mqtt, but I do have a lot of tasmota devices using the generic mqtt binding.

I followed your directions to create system broker, then changed my existing mqtt broker connection to a "systemBroker" and referenced it by brokerid (Broker Name).

I had one other issue, the new system broker wouldn't start up. I had to manually add secure="false" to /opt/openhab/userdata/config/org/openhab/mqttbroker.config .

Maybe you can get away with toggling "Secure Connection?" a couple of times.

Hey @fabyte and @ncollins!

I just want you to know, that I'm still there, but out of time at the moment. My third child was born just recently and I don't have any time for the binding at the moment.
I'm really sorry you had to reverse engineer the binding to add your code. That's awfully wrong.
We need to create a new common base to continue the work on the binding.
I was not able to add the binding to the official repo because of the formal requirements from the Openhab Team. I'm sure these requirements are needed, but I'm no professional in java. I struggled mainly at the nonnull annotations that are needed.

[fabyte]

@TimO Congratulations on your child :clap:
I know it's an exciting time and definitely more important than developing a OH binding :grin:
Spending time with your family should always be number 1 priority and you can't blame anyone for taking time off from a internet community :)

[ncollins]

@TimO Congrats!

I've been looking some of the other addon-ons and your code actually looks a lot better than most. I think the base is pretty solid.

I'll take a look at the annotations, and maybe getting some more traditional unit tests in place.

If we get to a point where a merge is acceptable, maybe we can move the maintenance fork to the MySensors repo.

[ncollins]

@TimO & @fabyte I took a stab at making all of the classes/interfaces @NonNullByDefault and adding/overriding null checks throughout. It builds fine, seems to be working well with my ethernet gateway.

I'm going to look at unit testing next.

@ncollins

I have been trying to get MySensors working with OH3 for a few days now and have just stumbled upon this thread. How opportune!!!

I am just trying to get a temp/hum arduino nano with a NRF24L01 hooked up to PI400 with OH3 using this link:

https://www.smarthomeblog.net/diy-home-automation-sensors-first-node/

Since I am starting from scratch with a simple proof of concept there might be some easy testing to be done with my setup.

Do you have any suggestions for me?

Thanks!

[ncollins]

@haloway13 Glad to see you're diving in.

Have you set up your gateway yet? If not, try this https://www.mysensors.org/build/raspberry. I find it's easier to build and debug node with a working gateway.

[haloway13]

@ncollins

I believe so.

[ncollins]

@haloway13 Looks good.

Next, I would get openhab ready for adding the mysensors addon. https://github.com/tobof/openhab2-addons/wiki/Installation

Via the openhab console run the following to install/activate the binding dependencies:
feature:install openhab-transport-serial
feature:install openhab-core-io-transport-mqtt
I recommend also setting log:set DEBUG org.openhab.binding.mysensors

Create a mqtt system connection in OpenHAB. Be sure to check advanced, and set the port.

Then you can drop the org.openhab.binding.mysensors.jar into the addons folder and it should auto install. You can start with the binding linked above.

Once all of that is done, you can configure your first thing, which would be a MySensors MQTT Bridge. (you should disable "Enables the startup check", I believe there is a bug)

[haloway13]

@ncollins I have had some issues getting this going. Am I running the development branch? Can you tell from the output?

[ncollins]

@haloway13 you have any logs or screenshots of errors you're seeing?

[haloway13]

@ncollins best I can do is say that it was a java io exception of some sort associated with the bridge or broker. I have since started from scratch several times and have not taken any screenshots.

I have faithfully followed directions from: https://github.com/tobof/openhab2-addons/wiki/Installation

Then it is a bit of a mystery to me how to finish up the configuration through the web pages.

Any help would be greatly appreciated!

[ncollins]

Hmm, I don't use openhabian, but it looks like there is a log viewer built in: http://openhabian:9001 (maybe change openhabian to the IP of your pi).

Without logs or screenshots, it'll be impossible to help.
