This RF Bridge can convert many 433MHz RF Remote Controllers into WiFi wireless.

The RF Bridge can be used with many 433MHz products, e.g. RF remote controllers, RF controlled switches, RF controlled sockets, RF controlled bulb, RF controlled door openers, door magnetic sensors and RF movement detection IR sensors.

This product is based on the Sonoff RF Bridge, but has an alternative software. EweLink is NOT supported.

No support for dynamic and rolling codes.



    What is ESPurna?

    ESPurna ("spark" in Catalan) is a custom firmware for ESP8285/ESP8266 based smart switches, lights and sensors.

    It supports a number of SONOFF devices and feaures e.g. MQTT and Home Assistant integration.

    You may find more information on github.

    Beware that it requires effort and IT skills to configure and integrate ESPurna devices with home automation systems. This is not products for novices.
