OH3 - MySensors Binding

[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.

@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.

Here is how I configured the thing:

[haloway13]

@fabyte

Could you post config screens for each of the things above for me?

Thanks!

[ncollins]

One thing I had to do was explicitly set secure="false" into /opt/openhab/userdata/config/org/openhab/mqttbroker.config.

Please try that, then restart.

[ncollins]

also, is your MQTT broker password protected? if not, remove the username and password from your system broker configuration.

[haloway13]

@ncollins
I will check tonight.

I really appreciate all help so far.

When you refer to the broker password: do you mean when you install the mqtt using the openhabian-config utility from the command line while being logged in with ssh to the Pi?

[fabyte]

@haloway13 I had exactly the same problem.
Here is what I did to fix it:

1. uninstalled the mqtt binding
   1.1 make sure the /opt/openhab/userdata/config/org/openhab/mqttbroker.config is removed
2. installed the mqtt binding
3. setup the system broker

After that, the system broker connection could be established and the Try to restore connection to '192.168.1.151'. Next attempt in 60000ms messaged disappeared.

Then you can proceed and set up the MySensors MQTT Bridge.

[ncollins]

@haloway13 yeah, when you did the initial mqtt setup, did you protect it with a password? If not, make sure you clear out the username and password from the OpenHAB broker settings. (I’m not sure if it will fail if you provide credentials to an instance that is not password protected)

[haloway13]

@fabyte

I am not showing such a file as mentioned in 1.1

2 & 3 refer to using the web interface?

Thanks!

[fabyte]

@haloway13 Yes, everything via the web interface
