The Sonoff RFR2 Smart Switch combines reliable appliance control with flexible wireless connectivity. Its core is a robust 10A relay, safely switching AC loads up to 2200W, making it ideal for integrating lights, pumps, or small motors into a smart home ecosystem. The module operates on standard 90-250V AC power, drawing its operational supply directly from the mains line for a clean, wire-in installation.
This device establishes a local connection via its built-in 433MHz superheterodyne RF receiver, compatible with standard 433.92MHz remotes, while simultaneously connecting to your home’s 2.4GHz Wi-Fi network. The dual-radio architecture allows for fallback control; you can use a physical RF remote within range or the EWeLink cloud platform from anywhere. The ESP8285-based system ensures stable connectivity and supports OTA firmware updates for feature enhancements and security patches.
