  • Product description

    Smart relay switch | 1-channel | 10A | 2200W | 100-240V | Wi-Fi | SONOFF | RFR2

    SONOFF RFR2 is a single-channel Wi-Fi relay with a built-in RF 433 MHz receiver, wired inline in the cable. It switches loads up to 10 A via the app, voice and a 433 MHz remote or wireless switch.

    Key idea:
    The relay lets you control an appliance or lamp both over the internet and locally with an RF remote – even when the Wi-Fi network is down.
    Load
    10 A / 2200 W
    Connectivity
    Wi-Fi 2.4 GHz + RF 433 MHz
    Mounting
    inline in the cable
    Dimensions
    91 × 43 × 25 mm

    How it works

    The relay is wired between the supply and the load: phase and neutral at the input, the controlled appliance at the output.

    Over Wi-Fi the relay is controlled with the eWeLink app, Alexa or Google Assistant voice and schedules.

    The built-in RF receiver learns the button code of a 433 MHz remote (e.g. RM433R2) or wireless switch (T2EU2C-RF) and works without internet.

    Why choose RFR2?
    Two control methods in one: remote via the app and local with an RF remote, so control remains even if the internet goes down.
