Sonoff RF Bridge

This compact bridge acts as a translator between 433MHz RF signals and Wi-Fi, allowing RF remotes and sensors to be managed like smart devices. It supports up to 16 RF remote buttons and 4 RF alarms, which can be configured to trigger scenes or send alerts.

The RF Bridge is compatible with Sonoff RF devices such as the Sonoff PIR2 motion sensor, DW1 door/window sensor, and Sonoff 4-button RF remote. It also works with many third-party 433MHz devices using EV1527 encoding.

Users can create smart scenes that respond to RF triggers—like turning on lights when motion is detected or sending notifications when a door opens. The bridge connects to 2.4GHz Wi-Fi, and setup is done via the eWeLink app.
