Smart Wi‑Fi and RF Wall Switch Sonoff RFR2 — 230VAC, up to 2200W

Sonoff RFR2 is a smart Wi‑Fi and RF wall switch for 230VAC mains, enabling remote on/off control of lights and appliances. Designed for retrofit or new installations, this single‑gang switch supports Wi‑Fi control and RF433 remote control, and handles up to 10A (2200W). The device integrates with smart home ecosystems to provide scheduled actions, grouped control and status synchronization in the companion app.

Advantages

RFR2 combines Wi‑Fi and RF433 control methods, allowing app control, voice control via Alexa and Google Home, and manual operation. The enclosure uses fire‑resistant PC material (LexanTM PC940) and the product design follows safety principles such as extended creepage distances, reliable terminals that comply with UL 1059, moisture and dust resistance, and tested mechanical strength and environmental durability. The switch supports grouping of devices, status sync on the app, timing schedules and scene triggers with compatible sensors and remotes.

How to use

Install the Sonoff RFR2 in place of an existing single‑gang wall switch or mount it during new installations, ensuring mains power is disconnected before wiring. Connect live and load conductors to the designated terminals and secure external wires under the terminal screws. Restore power and pair the device to the eWeLink (or compatible) app over 2.4GHz Wi‑Fi, or pair RF433 remotes as needed. Use the app, an RF remote, or voice assistants to turn appliances on and off, create schedules, and include the device in groups or scenes.

Usage recommendations

For safe operation, use the switch only within rated voltage and load limits (max. 10A/2200W). Ensure wiring is performed by a qualified electrician, confirm secure terminal connections, and avoid exposure to prolonged extreme humidity or temperatures beyond tested limits. Pair the device on a stable 2.4GHz Wi‑Fi network and follow local electrical codes when installing.
