433 MHz devices are used everywhere because they are cheap and easy to use. In this video, I will build an affordable gateway which transfers 433MHz messages via Wi-Fi to out MQTT broker. The device uses RFLink firmware on an Arduino Mega and an old ESP8266 (ESP-01) module.
Then I connect my new Chinese Weather Station to this gateway and, through some Node-Red porn, get the data neatly on a browser screen. It also can be used to steer all sorts of other devices.
