Description
The Sonoff RF Bridge R2 serves as a critical protocol translator in a smart home ecosystem, designed to bring legacy 433MHz RF-controlled devices into the modern IoT landscape. It features a dual-radio architecture, integrating a standard 802.11b/g/n Wi-Fi transceiver for network connectivity and a sensitive 433MHz receiver for capturing signals from a wide array of inexpensive wireless remotes, switches, and security sensors.
Engineered for reliability, the bridge operates on a simple 5V USB power supply and manages device pairings through the eWeLink mobile application. It supports advanced automation features, including the creation of eight schedule, countdown, or loop timers, and facilitates DIY smart scenes that trigger actions based on sensor inputs. Its integration capability extends to major voice assistant platforms, providing hands-free control over a previously isolated set of RF devices.
