MOD: Add 433 MHz transmitter feature for control RC socket #1523

Idea You have a low-power USB power supply and a powerful LED power supply that only needs power when the LEDs are on.

Basic implementation You have a relay that breaks the wire to the LED power supply. But you need to cut the live wire with a relay, which can be dangerous due to the poor quality of the relay module.

My implementation You have a stock 433MHz RC power socket that breaks power for LED power supply. Advantages: you don't need to cut the power cable Disadvantages: use of externally vulnerable radio protocols

All configs are made with defines and written as new build config. The assembly uses the rc-switch library as a dependency.

Thanks everyone for the WLED project!

Hey, did you add this kind of 433mhz tx to the esp? rf-link-transmitter-receiver-module-pair-433mhz-or-315mhz-for-arduino-raspberry-pi-b-b

Yes, I used the RX module and the sample sketch for it to get the keycodes and define them as build_flags (RCON/RCOFF), so now it only uses the TX module and transmits the command at the same time as the relay module in the original program. Works well at 3.3 volts over a short distance (about 0.5 meters / 20 inches) without an antenna. TX connected to GPIO15 (D8) (RCPIN in build_flags).
