notes

Usage:
Create a new directory & save the two files in it, then open up your CMD/Terminal, navigate to that folder & execute `npm install`, after that launch the script with `node index.js` -> if you find a Homematic/eq-3 LAN device, please post the output in the comments, that would be very helpful :)

Hi there,

My Yamaha R-N803D's LOCATION field is named Location.
I've fixed this by replacing line 10 with:

var start = msg.search(/location:/i) + 'LOCATION:'.length;

Regards,
