HomeEasy/Nexa control question


I am fairly new to this and I am having some trouble.

I have loaded this library


to control my lights wich is hooked up to a Nexa dimmer.

In the example code on the page it says:

// Your remote id which can be it can be "sniffed" with the // reciever example at http://playground.arduino.cc/Code/HomeEasy

I can't find an easy way to do this. Do I really need a oscilloscope to do this?

Anyone on the forum that as been playing around with Homeeasy/Nexa?
