@AWI But this does lead to another kind of problem. If I want to add another sensor to net and its address is between two another sensors, the sketch will change child_ids to new order.
In the controller head it means that controller thinks that child_id is same sensor and charts gets confused..
This means too that i cannot put sensors one by one.
How should I do this so I can say for real that my sensor one is in livingroom and three sensors are in different bedrooms and so on...
It was easy when I had plaine arduino and lcd witch showed temps one by one...
