Hi there,
I would like to have my wall switch to send a short rf signal when either turning on or off.
I believe what I am looking for is a 220v to 5v acdc, followed by a edge detector (both when transitioning from off to on and vice versa), followed by a rf transmitter activated by the pulses generated by the edge detector.
Can anyone recommend an easy way to achieve this? I cannot be the first person needing this
Thank you!
