PIN 2 transmitter (DATA) on ARDUINO PIN 11 (and not ARDUINO PIN TX 1)Ģ.Receiver Pin 5 (DATA) on ARDUINO PIN 10 (and not ARDUINO PIN RX 0).The wiring must therefore be modified as follows: I noticed that the TX and RX PINs used do not work very well.

I used another transmitter and another receiver than those offered (1 FS1000A 433mhz transmitter and 1 XY-MK-5V 433mhz receiver).

We will start with the wiring, taking as a basis the tutorial from (with my thanks in passing). You just need to peel off and shift the black plastic a little to make these functions work and retrieve the codes generated (see continuation of the tutorial).ġ. This will allow RFLINK (433MHZ) to be used via Home Assistant on a Arduino Uno ( and not Arduino Mega) to control CHACON (DIO) sockets.ġ Raspberry PI4, 4GB (and an SD card of course).ġ FS1000A 433mhz transmitter (with a soldered electric wire for the antenna)ġ XY-MK-5V 433mhz receiver (with a soldered electric wire for the antenna)įor the remote control, very useful information hidden behind the black plastic: two additional functions: ALL ON and ALL OFF. First tutorial which I hope can be used by other people!
