Zigbee Relay board communication with Arduino I have bought this wireless ZigBee relay board.

I was wandering about an arduino sketch to get started, I have searched for 2 days now but with no results.

What I was thinking of is to have an Arduino with ZigBee module to send signal to another ZigBee device on top of the relay, to be able to open/close relay.

So, can anyone share a sample sketch for that board?
Take a look at this library : https://code.google.com/p/xbee-arduino/

This is the XBee Library for Arduino, you will find simple sketch that are perfect bases for the application you're trying to do.
