Sonoff 433.92MHz RF WiFi Bridge

Already flashed with the latest Tasmota firmware.

RF433,92MHz and Wi-Fi Protocol Support Helps you connect 433,92MHz RF devices with Wi-Fi devices and expand the smart home ecosystem.

Strong Connectivity, Limitless Possibilities - The bridge supports adding up to 64 RF 433,92MHz devices released by SONOFF, such as the PIR3-RF PIR motion sensor and the DW2-RF wireless door/window sensor, making your home smarter.

Additional Device Types - The bridge also recognizes signals from 433.92MHz smoke detectors, 433.92MHz door magnet sensors, 433.92MHz human body IR motion sensors, 433.92MHz water sensors, and many other 433.92MHz sensors. The requirement is that these devices operate with a code such as PT2260, PT2262, PT2264, or EV1527. However, rolling codes and dynamic codes, such as those used in garage door openers, roller shutters, and curtain controls, are not supported.

Compatible with 433,92MHz Remote Controllers & Easy Management - If you have dozens of RF433,92MHz devices and are having trouble controlling them, this RF BridgeR2 will help you organize everything. Just migrate the devices to your smartphone. It is compatible with 433,92MHz remote controllers for easier control. You can add up to 16 devices and up to 64 buttons.

RF Alarm & Trigger Smart Scenes - You can add alarms to trigger the device by setting up a smart scene. For example, once the door is opened (in conjunction with the DW2 door/window sensor), you will receive a notification and the lights will turn on automatically.

Optional Portisch Firmware – Unlock More Features

The RF Bridge R2 can optionally be upgraded with the so-called Portisch firmware (flashed separately to the RF chip). This enables additional functions and greater flexibility in RF signal handling:

Extended Device Support – Adds compatibility with a wider range of 433 MHz devices and non-standard protocols.

RAW Signal Send & Receive – Capture and replay unknown RF signals for advanced control and diagnostics.

Faster Signal Processing – RF data is forwarded immediately upon reception instead of waiting for the transmission to end.

Tasmota Compatibility – Tasmota supports both the original Sonoff RF firmware and the optional Portisch firmware.

Important Notice:

The RF Bridge R2 supports only the frequency of 433.92 MHz with static codes (e.g., PT2260, PT2262, PT2264, EV1527, etc.). The standard firmware only receives radio signals that can be interpreted by the RF processor. With the optional Portisch firmware, this limitation is significantly extended — including RAW data reception and support for additional device types.

Rolling codes and dynamic coding (e.g., used by garage door openers, roller shutters, or awnings) are not supported — even with Portisch.
