The Sonoff RFR2 is a dual-protocol wireless remote control switch that combines WiFi and 433MHz RF functionality for seamless smart home automation. Home automation professionals, electricians, and IoT integrators rely on this device to retrofit existing electrical installations with voice control and mobile app capabilities without rewiring. It solves the critical problem of adding smart control to legacy appliances and circuits while maintaining backward compatibility with existing RF remote systems.
Product Overview
The Sonoff RFR2 operates on a hybrid dual-protocol architecture, supporting both WiFi connectivity for cloud-based control and 433MHz RF reception for wireless remote operation. The device functions as an intelligent relay module with a 10A rated load capacity, integrating directly into standard electrical switch boxes or panel installations. Its microprocessor-based design enables real-time switching logic, allowing simultaneous control through multiple interfaces including the native eWeLink mobile application, voice assistants, and physical RF remotes. The 433MHz receiver operates at industry-standard frequency with rolling code technology to prevent signal jamming and unauthorized control.
What distinguishes the RFR2 from standard smart switches is its ability to function in three independent control modes simultaneously without mode switching. The WiFi module supports 2.4GHz IEEE 802.11b/g/n standards with WPA2 encryption, ensuring secure cloud connectivity. The RF receiver maintains a 100-meter effective range in open space with obstacle penetration capability through standard building materials. The device includes a learning mode for programming RF remote codes, making it compatible with existing Sonoff RF remote controls and third-party 433MHz remotes. Its compact form factor allows installation in tight electrical enclosures where traditional smart switches cannot fit.

How to Use
Installation begins with turning off power at the circuit breaker and identifying the load wire to be controlled. The RFR2 connects in series with the controlled circuit, with the input terminal receiving the live wire and the output terminal connecting to the load. Once installed and powered, download the eWeLink application and create an account. During the initial setup, the RFR2 enters pairing mode automatically, allowing the app to detect and configure the device on your home WiFi network. Complete the WiFi configuration by entering your network credentials and selecting a meaningful device name for voice control integration.
For RF remote functionality, access the learning mode through the eWeLink app or by pressing the physical button on the device. Point your existing RF remote at the RFR2 and press the button you wish to program. The device will learn and store the RF code, enabling control through that remote. Configure voice assistant integration by linking your eWeLink account to Alexa, Google Assistant, or Apple HomeKit through their respective smart home platforms. Create automation rules within the app to schedule on-off cycles, set time-based triggers, or establish conditional logic based on other smart home devices. Test all control methods before completing the installation to ensure proper operation across WiFi, RF, and voice channels.
Frequently Asked Questions
Can the Sonoff RFR2 control appliances that are currently controlled by physical wall switches?
Yes, the RFR2 is specifically designed for this purpose. Install it in parallel with your existing wall switch by connecting both the switch and the RFR2 to the same load circuit. This creates a hybrid control system where the appliance responds to both the physical switch and the wireless controls. The device will maintain state synchronization, ensuring accurate status reporting regardless of which control method was used last.
What is the maximum distance for 433MHz RF control, and does it work through walls?
The RFR2 has an effective RF range of 100 meters in open space. In typical residential environments with walls and obstacles, the practical range reduces to 20-30 meters depending on wall materials. Concrete and metal structures attenuate the signal more than drywall or wood. The 433MHz frequency penetrates standard building materials better than higher frequencies, making it suitable for multi-room control within most homes. For extended range requirements, use the WiFi control method through the eWeLink app, which operates globally with internet connectivity.
Is the Sonoff RFR2 compatible with non-Sonoff 433MHz remotes?
The RFR2 can learn and store codes from most standard 433MHz remote controls through its learning mode function. However, compatibility depends on the remote using standard rolling code or fixed code protocols. Some proprietary remotes with manufacturer-specific encryption may not be compatible. Test your remote by entering learning mode and attempting to program a button. The device will provide feedback through the app if the code was successfully learned. For best results, use official Sonoff RF remotes or universally compatible 433MHz remotes available in the market.
Can I control multiple Sonoff RFR2 devices from a single voice command?
Yes, voice assistant platforms support grouping and scene creation. Within the Alexa, Google Assistant, or Apple HomeKit app, create a group containing multiple RFR2 devices assigned to the same room or zone. Then create voice commands like "Alexa, turn off bedroom lights" to control all devices in that group simultaneously. The eWeLink app also supports creating custom automation scenes that trigger multiple devices with a single command or scheduled event.
