I recently installed an "Ubuntu 16.04 LTS" on a Raspberry 3 fully upgraded to evaluate some Z-Wave devices functionality. Now I see a high readKey load (15-20%) all around the clock which is not ok IMHO. What is it responsible for and is there a chance to get the reason of its running? The PPID is 1 by the way.
I can kill the process without losing any functionality which I am using.
