How to hack your 433 mHz device

[4L5A]

Hacking of 433 MHz or other RF devices is a human right for makers because these devices usually use proprietary protocols. Today we will reverse-engineer a so-called “professional” weather station from China and enable it to send its data via MQTT. Then we will hack the remote control of our outdoor awning and use an ESP32 to build a fake twin which understands MQTT. We will use a Raspberry Pi and Software Defined Radio (SDR). You will be astonished how professional this will get.
