Right, status reporting is all I'm wanting to achieve with this. I do prefer to do it from scratch, I just referenced that transmitter as an example. 8 lines will be more than enough for me, 4 will will actually do just fine.

So let's say I have the Linx TX unit and I only want it to report one single button closure on the machine to the receiver 30 feet away through one wall, and I'd like to keep it as simple as possible until I start to get a hold on this as I learn pretty fast once I get one basic thing working and can experiment from there. To keep it simple, lets forget about the LCD and just light an LED for now.

How would you recommend I do this ?

Much thanks.
