Itead Studio has been releasing interesting gadgets for the Home Automation community based on a low price tag and extreme hackability. You can google “sonoff” (the main brand for Itead Studio home automation devices) to get more than a million hits, including official pages, reviews and lots of hacks. The ubiquitous ESP8266 (or its sibling ESP8285) is the core of all those devices, using WiFi instead of the traditional RF messages, replacing a remote with mobile apps or voice commands. But also, using custom firmware like ESPurna, technologies and solutions like MQTT, Node-RED or Home Assistant. But one of the latests devices from the chinese firm tries to bridge the gap between those two technologies: the Sonoff RF Bridge 433.
