Gateway to detect signals in 433MHz band and translate them to a MQTT broker.
Each signal gets its own topic within given topic root. E.g. if you leave MQTT_TOPIC as "home/rf433/" then signal 12345678 will be published to "home/rf433/12345678".
I use this gateway to translate signals from differenet sensors around my house to a MQTT broker connected to Home Assistant server.
You will need a ESP8266 board and a 433MHz receiver module.
My personal favorites are WeMos D1 mini and RXB12 mounted on a prototyping shield.
