Lesson31- How to decode 433MHz RF signal and control device by ESPHome

KC868-A4 smart controller, many hardware resources for you to use, you can write any code by Arduino IDE to ESP32 wifi/Bluetooth module. We will supply demo codes for different samples. Everyone can modify and change the code for their own smart home automation system project.

I tried this with esp32. I receive data 29bytes long with protocol 1. Weird length, but whatever. Then when I try to transmit it and it won't go - it logs that I triggered switch but nothing further happens. I tried using another esp32, another set of transmitter/receiver, also another type of them too. Nothing. Any hints?
It's as if esphome rc_switch library is bugged.

[@KinCony]

which kincony's ESP32 board model you are using?

[@MGL83]

@@KinCony No kincony. Just ESP32 vroom 32 dev board.

Thank you, very helpful.

Can the remote receiver receive 433 to control the relay on KC868-A4

[@KinCony]

yes, no problem

[@meierthomas]

Thanks for the video. The KC868-A4 is an overkill for me as I only need RF send and receive. Do you know of any other modules that only do RF send/receive?

KC868-AG

[@meierthomas]

@@KinCony So if I'm not interested in IR (only need RF) what code would I use for ESPHome? I see code sample for the KC868-A4 but probably different to the KC868-AG

[@KinCony]

KC868-AG only use IR+RF, suppoprt ESPHome, we have sample yaml file in our forum.@@meierthomas

hello

I have a 433mhz siren i tried this but not working

[@KinCony]

433M is frequency, you need to confirm which wireless protocol using by the siren.

@@KinCony yes it is I had openmqttgateway working but I want to migrate to esphome

[@KinCony]

@@marine1718 you can use ESPHome RF decode the wireless signal, if can be decoded, that can be integrated.

[@marine1718]

@@KinCony I do have the code put there like you do in your video and then on homeassistant I click and does nothing
