@robertmt Yes I have similar problems :/ But have not had the time to look into this yet. Hopefully later today (or maybe closer to the weekend)

Hi. I have some progress. I can see data coming in terminal ... [INFO] [ runtime.busevents ] - Arduino state updated to 0;0;1;0;4;1009.0 0;1;1;0;0;22.0 0;2;1;0;1;61.0 and keep updating... (only 3 nodes so far) However on website still nothing... I assume there is something wrong with openhab config. What I did... Added serial bindings from this link ( http://forum.mysensors.org/topic/655/serial-gateway-connection-to-openhab/3 and updated demo.rules accordingly and also had to remove ... @115200 from demo.items - { serial="/dev/ttyACM0@115200" }
