Sonoff RF Bridge 433

Description : This RF Bridge 433 can convert most of the 433MHz RF Remotes into WiFi wireless. By adding the RF wireless Bridge to iOS/Android App eWeLink WiFi wirelessly, you can add up to four 1-4 buttons 433MHz Wireless RF Remotes or 433MHz sensors to the RF Bridge device. After pairing the 433Mhz RF Remote buttons with 433Mhz RF controlled devices, you can directly control maximum 16 RF controlled devices on the App through WiFi/2/3/4G network. It can be used for most of the 433MHz RF Remote controlled products, like RF controlled switch, RF controlled socket, RF controlled bulb, RF controlled door opener, etc. You can set totally 8 schedule/countdown/loop timers to turn on/off the RF controlled products. Even more exciting is that it will work with 433MHz door magnetic sensor, 433MHz human body IR sensor, and more other 433MHz sensors to realize security alarm, and allowing you to DIY smart scenes. Note that the alarm push only comes in the owner's account, those users being shared can't view the alarm push. Works With Amazon Alexa To control Sonoff RF Bridge, you'll need to say RF Remote name and button name together. Standard voice control commands phrases (if you just say the RF Remote name, Alexa will turn on/off all buttons of that RF Remote immediately): Alexa, turn on {RF Remote Name}Alexa, turn off {RF Remote Name} Alexa, turn on {RF Remote Name} {ButtonName}Alexa, turn off {RF Remote Name} {ButtonName} Specifications Power Supply: USB 5V Wireless Standard: WiFi 802.11b/g/n, 433MHz Security Mechanism: WPA-PSK/WPA2-PSK Product Dimensions: 62*62*20 (mm) Features for Sonoff DW1 Sensor Ultra-low power magnetic dedicated microprocessor Supports wireless frequency of 433.92MHz 200m wireless transmit distance Built-in antenna provided Less than 1μA quiescent current Specifications for Sonoff DW1 Sensor Support Battery: 12V 23A Wireless frequency: 433.92MHz Protocol: EV1527 Quiescent current: ≤5μA Emission current: ≤10mA Operating environment: -10℃-50℃ (14℉-122℉) Product Size: 77*49.5*18.8mm Battery: length 27mm, diameter 10mm, this model doesn’t come with battery Weight: 45g Features for Sonoff PIR2 sensor Dual infrared Ultra-low power microprocessors Double temperature compensation technology Robust and durable, suitable for homes, offices, sheds, garages etc. Easy installation and set-up, wall-mounted Specification for Sonoff PIR2 sensor Transmit distance: 150m (open) Voltage: 3V (2*AA) Standby current: ≤9μA Alarm current: ≤10mA Wireless frequency: 433.92MHz Wireless Transmit Code: 1527Mhz (default) Detection distance: 12m@ 25℃ Detection angle: 110 degrees Maximum coverage area: 12m*12m Alarm indicator light: on for 3 seconds Working environment: indoor Tamper switch: normally closed Anti-white light intensity: 10000Lux Packing size: 165*65*50mm Product Size: 120*62*46mm Battery type: 2*AA (Note: this model doesn’t come with battery) Weight: 120g Documents wiki
