Re: Motorola home control

I have no idea what protocol they use nor whether they use FSK or ASK but
most similar devices use ASK/OOK because it's simplest and lowest cost.

You can buy a 418MHz ASK receiver from Mouser - PN 509-RCR-418-RP FOR $4.26.

The data output will be in the audio range so you can record it as a .WAV
file using a soundcard line-in (It's IMPORTANT that you use line-in.) and
view it in almost any Wave editor.

I have illustrated this at...

     http://www.mbx-usa.com/learn.htm

The RF section is about half-way down the page.

For any final 'server' device, you'll need to interface the RF receiver with
something that can decode the data output. Unless you have experience in
programming microcontrollers, you'll be better off buying their 'server'.
