Hi all, and thanks for the previous posts.

I was having the same issue where the Bridge would stay as INITIALIZING. My set up is a little different as I use Openhan on docker with the following volumes mounting in /opt/openhab:

-v /etc/localtime:/etc/localtime:ro \
-v /etc/timezone:/etc/timezone:ro \
-v /opt/openhab/conf:/openhab/conf \
-v /opt/openhab/userdata:/openhab/userdata \
-v /opt/openhab/addons:/openhab/addons \
-v /opt/openhab/.java:/openhab/.java \

I'm using OH2.3 with the Docker Image: openhab/openhab:2.3.0-amd64-debian and the location of the org.eclipse.smarthome.mqttbroker.cfg file is in /opt/openhab/userdata/config/org/eclipse/smarthome.

After making all the changes above I couldn't get the Brdige to work, until finally I downloaded the MySensors addon 2.4.0 from http://www.oberfoell.com/openhab2/org.openhab.binding.mysensors-2.4.0-SNAPSHOT.jar as suggested by @MasMat and placed it in /opt/openhab/addons.

Immediately the status of the bridge changed to ONLINE.

Hope this helps sombedy.
