Wireless temperature transmission from multiple sources to one controller

tomasdelaveau:
I'm still awaiting for another UNO board to test your example codes,

What boards have got at the moment?

but I want to know how to code it for the emitter to send a temperature read from the MAX6675, and the receiver to compare it to one read from its own MAX6675 and control a relay depending on that.

Wireless problems can be very difficult to debug so get the wireless part working on its own before you start adding any other features.
