Do you sell a module (like maybe Xbee or a 433mhz transmit/receive module?) to wirelessly pass a GPIO signal to a relay? I’m running Falcon Pi Player on a Pi 4B and want to control a 110V light wirelessly with a GPIO signal. I know I could probably configure another Pi to listen over a wifi network and send the signal but I have no idea how to write a script for that.

Thanks!
