This is when i am not home.
Check time stamp

17:21 Motion Sensor TV 4 1 turned off
17:21 Motion Sensor TV 4 1 turned on
Just can't figure what makes it trigger on exact times.
Even if i reset the node it triggers on same times.

This is the sketch

/**
 * The MySensors Arduino library handles the wireless radio link and protocol
 * between your home built sensors/actuators and HA controller of choice.
 * 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.

 * REVISION HISTORY
 * Version 1.0 - Henrik Ekblad
 * 
 * DESCRIPTION
 * Example sketch showing how to create a node thay repeates messages
 * from nodes far from gateway back to gateway. 
 * It is important that nodes that has enabled repeater mode calls  
 * process() frequently. Repeaters should never sleep.

Even tried this sketch but i get the same result.
