This project is a prototype to command some home devices via RF433 from the internet.

EXPANDED TECHNICAL DETAILS

Protocol Bridge Architecture

This project acts as a gateway between legacy 433MHz wireless devices and a modern WiFi home network.

  • RF Reception: An XY-MK-5V (433MHz Receiver) captures data from devices like wireless doorbells, remote switches, or weather sensors. The Arduino uses the RCSwitch library to decode the OOK (On-Off Keying) signals.
  • Cloud Uplink: Once a valid RF code is intercepted, the ESP8266 module (or a WiFi-enabled board) connects to a local router and forwards the code to an MQTT broker or a service like OpenHAB or Home Assistant.

Practical Utility

This bridge allows you to integrate low-cost "No-Name" RF remotes into a smart home ecosystem, enabling you to control high-end smart lights with a standard 433MHz keyfob.
