Wall-mounted Transmitter Sonoff RF BRIDGER2 Wireless RF Battery Powered

The Sonoff RF BRIDGER2 is a wall-mounted, battery-powered 433MHz RF transmitter designed to convert traditional RF remotes and sensors into smart home inputs. With a compact 62 × 20 × 62 mm housing and FCC compliance, the RF BRIDGER2 links 433MHz devices to eWeLink via Wi‑Fi or ZigBee, enabling scene activation, group control and scheduled actions.

Advantages

The RF BRIDGER2 learns common 433MHz remotes and sensors, allowing a single button press to trigger scenes and control multiple devices simultaneously. Its battery operation and compact wall-mounted form factor make installation flexible. Compatibility with eWeLink provides options to trigger Wi‑Fi or ZigBee devices and set multiple timer types for automated control.

Suitable for

• Converting legacy 433MHz RF remotes into smart scene triggers
• Integrating 433MHz RF sensors into a home security setup
• Controlling multiple devices at once through a learned RF remote
• Scheduling on/off actions for non‑smart lights and sockets using RF

Key specifications

• Model: RF-BRIDGER2
• Frequency: 433 MHz
• Power: Battery powered (wall-mounted)
• Dimensions: 62 mm × 20 mm × 62 mm
• Compliance: FCC
• App/platform: eWeLink (supports Wi‑Fi and ZigBee device triggers)

How to use

Mount the RF BRIDGER2 on the wall and install the required batteries. Use the eWeLink app to put the bridge into learning mode, then press the button on your existing 433MHz remote or activate a compatible RF sensor to teach the signal. After learning, assign the learned remote or sensor to scenes or devices in eWeLink so a single button press can trigger Wi‑Fi or ZigBee devices, or control multiple devices at once.

Recommendations

Place the RF BRIDGER2 within reliable RF range of your 433MHz remotes and sensors and within Wi‑Fi coverage for eWeLink connectivity; test learned commands and timers after setup to ensure correct operation.
