@Jan-Gatzke That seemed to work. I'm getting readable data now. Thanks!
I also set the nodeId to 15 (The above example assumed it was set to 101), as follows in the sensor
gw.begin(NULL, 15);
I adjusted the mapping accordingly in the mapping, as specified in the tutorial using 15 instead of 101. The following is now being output from event.log
