The 2.5-version of the binding does not work out of the box in OpenHAB 3 for me.

I guess it might have something to do with this?

Namespace change of openHAB core classes
With the migration of Eclipse Smart Home to openHAB the namespace of all classes in openHAB core needed to be changed. This means all imports done by bindings that refer to org.eclipse.smarthome have been changed to org.openhab.core. With your binding code you can simply do a file level replace of this text string in the java source files to migrate the binding. On linux you can use the following commands in you src/main/java directory:
find . -name *.java -exec sed -i "s/org.eclipse.smarthome.core/org.openhab.core/g" {} ;
find . -name *.java -exec sed -i "s/org.eclipse.smarthome/org.openhab.core/g" {} ;
Replying myself after more reading and testing.
*MQTT vs ETH probably is equivalent in my system, if the choice if given I think MQTT is preferred.
*NRF24 or RFM69, maybe both as I already have a bunch of NRF24 radios home and can start build directly.
*PC based MQTT could be an idea, but probably its as easy to work through an Arduino-example using the serial monitor in an Arduino-environment.
My way forward will be:
Remove the RPi-GPIO-gateway (I built a basic node and tested it, but could not communicate with the GW) and replace it with ESP8266-based WIFI/MQTT/Radio-gateway (one with NRF24 and eventually one with RFM69).
I believe that will be an easier way into mySensors-world also limiting the amount of required Linux-related knowledge. It will be easier to debug the system from Arduino IDE-serial console. Ie start and confirm OH3 to MySensors-MQTT-gateway, then proceeding with sensor to gateway communication etc.
@CyborgAndy said in OH3 - MySensors Binding:
@mbedarff @ncollins I published all changes to GitHub, "mysensors-binding-addon" branch.
Is it normal than the add-on is not displayed on the official listing available through the UI of openHAB 3.3.0?

Check out Serial Protocol
I have four Arduinos. Each has a different MY_NODE_IDs (I use 130, 131, 132, 133). Each has four sensors: moisture, humidity, temperature, and voltage each of which has a CHILD_ID: CHILD_ID_MOISTURE is 0 , CHILD_ID_HUMIDITY is 1, CHILD_ID_TEMPERATURE is 2, CHILD_ID_VOLTAGE is 3.
When an Arduino makes a measurement, it sends that measurement to a unique MQTT topic. In the case of the Arduino with MY_NODE_ID of 130 that is sending the moisture measurement, that MQTT topic is mysensors_out/130/0/1/0/35 and the message is [something like] 760 (35 is the value type)
Similarly, when a controller sends a command to a device (Arduino), the topic is unique.
If you have two actuators with the same MY_NODE_ID and CHILD_ID (MQTT topic) there would be confusion as to what you want each actuator to do. Likewise, if two sensors had the same MQTT topic, how would the controller know how to handle the data.
