Sonoff Wi-Fi Smart Switch with RF Control 10A / RFR2

Sonoff Wi-Fi Smart Switch with RF Control 10A / RFR2

The SONOFF RFR2 is a single-channel Wi-Fi smart switch with a built-in 433.92 MHz RF receiver. It is wired inline between the power supply and an appliance, so the appliance can be switched on and off from the eWeLink app, by voice, on a schedule or with a 433 MHz RF remote. It handles loads up to 10A / 2200W on 100-240V AC.

Two ways to control it: Over Wi-Fi, you control the switch from anywhere with the eWeLink app on your phone. The 433.92 MHz RF receiver also lets you use a common 433 MHz remote control; RF control works locally without the internet, so a remote still switches the appliance when your Wi-Fi or internet is down.

Schedules and smart scenes: In the eWeLink app you can set timing schedules so the appliance turns on and off automatically, create smart scenes with other devices, group devices for control together, and share control with family members.

Voice control: The RFR2 works with Amazon Alexa and Google Assistant, so you can switch the connected appliance by voice once the switch is added to your assistant.

Flame-retardant housing: The casing is made of PC with a V0 flame-retardant rating, which matters for a device that sits in the mains wiring of your home.

Who it's for / Works with

Making an existing light or appliance smart by installing the switch inline in its power supply. Works with the eWeLink app, Amazon Alexa, Google Assistant and common 433 MHz RF remote controls.

Good to know
