Thanks hek, Did it a bit different, but probably with the result i wanted. In the repeaternode sketch I used the following line: gw.begin(NULL,4,true); This created a repeater node with node-id 4 (just an arbitrary number) In the Dallastemperature example I used: gw.begin(NULL,5,false,4) This created the sensor node with id=5, talking via repeaternode 4 to the serial gateway. This works. See the info from the temperature sensor being relayed to the serial-gateway. I haven't tried the method you suggested yet, but this sounds interesting of course. Wiil do that after Christmas I think. Boozz

@daulagari said: that makes sense although not from an user perspective Of coarse not. I just wanted to sketch the idea behind it.
