DIY 3 Channel wireless light switch controller

Simon combined the guts from three wireless power switches into one box – “5 years ago I had three RF controlled light switches each on a different channel. I wanted to combine the three remotes into one and this is the result. I added 3 new colored buttons and powered all three with one battery. It is cheaper than X-10 and the receivers will properly handle non inductive and high amperage loads. I did not modify the reciever ends at all. These RF controlled switches can be bought cheaply at any Home Depot type place – make sure you don’t buy 2 of the same channel which is indicated by a letter code. “Link.

    Did you look at the boards to see if there’s an obvious difference that decides the channel? Maybe you could have used a single board to do all 3.

    If I remember correctly, each board uses a different frequency crystal. I had to buy 3 boards since I needed 3 recievers anyway.

    Interesting. I would have expected modern electronics to a single freqency with multiple possible signals.

    When I said 1 board would have been good, I was thinking more about the total size of the remote.
