I bought a 315Mhz transmitter/receiver pair of postage stamp size boards from robotshop.com. Ebay has them too.

Here is the schematic:

Here is the board layout, which should be redone in surface mount parts some day. I used drawer junk parts and old VCR parts: 315Mhz wireless remote-switch 120vac-off-on.png

Here is the LTspice simulation of the 60Hz data received signal filter of ON and OFF button presses (2Hz to 12000Hz response curve): LTspice of data input filter 2Hz-12000Hz.png

Here is LTspice of the 1s and 3s hold for OFF using pulses from V1 which is imitating the 60Hz converted to 0.7vdc from previous LTspice. See 3 second delayed OFF and instant-ON effect: LTspice 60Hz for 1second goes through to Q2 as 0.7vdc.png
