@kimot No, it is an obvious mistake, I am very sorry. Maybe it is becouse the code in master branch is very old, the newest is not yet on github, but the developement branch is quite new. I am going to fix this soon.
@alexeinz figured it out, apparently had to add experimental and get latest mosquitto for the conf file to work correctly , now the bridge is working perfectly
--- broker.conf file in /etc/mosquitto/conf.d
the topics coming from gw will appear under sensor/# on mosquitto
address 192.168.1.234 <-gw ip
topic # in 2 sensor/ MyMQTT/
Ive started out with openHAB2. I was using a Ethernet gateway and tested the mysensors binding but found the combo was too limited. I much prefer having the MQTT gateway and the data be accessible to anything that subscribes, although I also now use openHAB to republish its item changes to MQTT as well which is probably a better approach.
I don't think the main new features in version 2 are very mature at the moment as well, discovered things for example get put in to a non human readable database and the web ui's are not fully functional.
With that being said I'm using node red to provide node ID's and configuring items manually and since beta3 it's been solid as a rock.
I think that:
It does overlap with MySensors for the wireless network. MQTT-SN assumes a network that provides a bi-directional data transfer service between any node and a particular one (a gateway). MySensors wireless network could provide data transfer but the message are really tailored to transport sensor and actuator values.
MQTT-SN for the gateway - controller interface is not needed MQTT is for that more than fine
That said I like the idea of MQTT-SN but for it a "transparent network" makes more sense.
I may have found a solution to my problem, I have to test a few days to be sure.
Hard my domoticz installation I have two raspberry one in server the second in client.
The raspberry server is connected to the USB gateway and on the second I have configured the ethernet gateway.
I keep you informed if I still have crashes.
