Remote (over the air) GPIO control Sodaq one

I am using the Sodaq one V2 for over two week now and my experiences so far are very positive!
i want to extend the basic tracker software with remote (over the air) control of some GPIO pins.
Can somebody point me in the direction how I can implement this. Maybe there is a very easy way like using the remote re-configuration as a ‘vehicle’ to control the IO

You can modify the void updateConfigOverTheAir() this handles the received data.
