@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

Great tutorial! Thank you for putting this together.

My controller is on RPi, and I'm using a Nano for mySerial gateway with the USB plugged into the RPi. When I specify the port as follows I get the following message

String Arduino "Arduino" { serial="/dev/ttyUSB0@115200" }

org.openhab.model.item.binding.BindingConfigParseException: Could not open serial port /dev/ttyUSB0@115200: Serial port '/dev/ttyUSB0@115200' could not be found. Available ports are:
/dev/ttyUSB0

MySensors.h has the following
#define BAUD_RATE 115200

I tried taking out @115200, I see openhab.log showing it trying to read garbage and the rules failing. So, I', thinking the garbage is because openhab is not reading it with the right baud rate. However, openhab on the RPi doesn't like /dev/ttyUSB0@115200

Any ideas anyone?
