I have a newbie-pcb board with a Dallas temperature sensor attached. I mixed some sketches together to make it work.
When starting the sensor the first time I can see all the actions performed. Reading temperature and battery percentage. But than after sleeping it is only reading and sending battery percentage (no voltage)? No temperature action is visible any-more. So, there must be a fault in my sketch which makes it read the temperature part only once? Any advice on this? Thanks.

* The MySensors Arduino library handles the wireless radio link and protocol

* The sensors forms a self healing radio network with optional repeaters. Each
* repeater and gateway builds a routing tables in EEPROM which keeps track of the
* network topology allowing messages to be routed to nodes.
