Great, thanks.
The sketch now works as it should.
Below is the finished sketch.
I also added a counter so that after 10 consecutive interrupts from the motion sensor, the temp and hum get read and transmited. (motion-on generates an interrupt and motion-off generates an interrupt, so it's actually 5 motion triggers)
Otherwise if there is a lot of movement during a certain timeframe (mornings), hum and temp won't be measured.
Later I will edit the sketch to have all transmits together to save more battery power.
Here's 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.
