Sonoff RFR2 Smart Home Light Controller Wired & Wireless White

Sonoff RFR2 Smart Home Light Controller Wired & Wireless is a compact smart switch designed to add remote and automated control to home lighting. Supporting both wired and wireless connections, the device operates on Wi‑Fi with AC power (100–240V) and fits into tight spaces with dimensions of 88 × 39 × 24 mm. RFR2 focuses on safety and reliability through reinforced mechanical design, environmental resistance and fire‑retardant enclosure materials.

Advantages

The RFR2 provides durable mechanical strength with a tested 30 N pull/push resistance and increased creepage and clearance distances (>3 mm) that exceed common regional standards. It is designed for moisture and dust resistance, surviving a 48‑hour 95% relative humidity test at 25°C, and can operate continuously at elevated and low temperatures under rated load. The enclosure is made from Lexan PC940 for UL‑94 V0 flame retardancy, terminals comply with UL 1059, and additional insulation measures (for example, heat‑shrink sleeving over the internal fuse) enhance electrical safety. The unit synchronizes status with the app, supports grouping of devices, voice control via Alexa and Google Home, scheduling and trigger‑based scenes with Sonoff sensors.

Suitable for

• Retrofitting conventional lighting to smart control in homes
• Integrating wired lights into Wi‑Fi smart home systems
• Automating outdoor or indoor circuits that require timed switching
