@joshmosh When a node presents it's sensors it sends out child id's. So the controller knows which child id's exist. When values are send to the controller this is in combination with the sensor child id. So the controller knows which value belongs to which child id's exist. If you then look at it pure from controller perspective it just sees multiple sensors. You can even put all your values within the same child id as long as the V_* types are unique used with that child id (do not use two V_TEMP values with the same child id).

@fot said: Hi! I ask my gateway about it's version (0;0;3;0;2;). It will responde with the library version number (1.4.1 in my case). It tells me that the gateway software is up and running. But it will not give me any clue about if the (NRF)network is working. That's a problem, right. I only ask the gateway if no other packages are received in $timeout seconds. /Magnus Of course ! Thank you for pushing my nose on it. Sometimes you don't see the most obvious ;-) Since my gateway is relatively close to the controller (Domoticz on a Raspi), I can do a hard reset of the gateway (via Raspi GPIO), which should resolve the issue. Cheers Josh

This is working in the development branch now.

@hek: Ah, ok, thanks a lot ! That gives some clarification and will hopefully help to catch the bugs. Thank you ! Josh
