Hi Raspberry Pi Community,

I would like to use radio remote's control to trigger an events on my Raspberry pi.

I guess I'll go with 433Mhz as I believe they are the most common available ?

So I will need a 433Mhz RX/TX Module to connect on the GPIO, so far I get it...

But how properly secure the communication between those remotes and the RPI to avoid any anyone to sniff the transmitting and replay it. In other words spoof it.

Wubba Lubba dub-dub...
