Found the answer in this tread https://forum.mysensors.org/topic/1086/getting-childid-from-incomingmessage/6 Will try this if (message.type==V_LIGHT && message.sensor==3)

Im not home right now but gateway is v 1.5 and almost all sensors is also 1.5 recept 1 or 2 at 1.4.. Distance vary alot between 1 to 50 meters from the gateway. I've traced the problem to the gateway though, it loses connection to my Vera for some unknown reson

@hek said: @bluman Candidate for the project contest perhaps? If all my parts turn up from China in time then it should be ready to submit for judging!
