    SONOFF POWR3 is a high-power Wi-Fi switch with energy metering (25 A, 5500 W). It shows power, current and voltage, stores history for up to 100 days and cuts the power when a fault is detected. Controlled with the eWeLink app and by voice.

  • Product description

    Smart switch with energy metering | 1-channel | 25A | 5500W | 100-240V | Wi-Fi | SONOFF | POWR3

    SONOFF POWR3 is a powerful single-channel Wi-Fi switch with energy metering for loads up to 25 A / 5500 W. It switches an appliance or circuit on and off and shows power, current and voltage in real time in the eWeLink app.

    Key idea:
    When you need to control higher-power equipment – a water heater, heater, sauna stove or an entire room circuit – and see its consumption, POWR3 does this without a separate contactor up to 25 A.

    How it works

    The switch is installed in the circuit between the supply and the load: phase and neutral are connected, and the output goes to the controlled appliance or circuit up to 25 A.

    Connected to 2.4 GHz Wi-Fi, POWR3 shows real-time power, current and voltage in the eWeLink app, stores consumption history for up to 100 days and allows export in CSV format.

    By constantly monitoring the parameters, POWR3 automatically cuts the power when it detects a fault, protecting the appliance. The result: remote control, schedules and consumption control.

    Why choose POWR3?
    The 25 A / 5500 W load rating allows direct control of high-power appliances, and energy metering with protective disconnection gives more control than a simple switch.

    Main functions

    • High load – up to 25 A / 5500 W without a separate contactor.
    • Energy metering – real-time power, current and voltage.
    • Consumption history – up to 100 days with CSV export.
    • Protective disconnection – power is cut when a fault is detected.
    • Schedules and scenes – the appliance runs only when needed.
    • Voice control – Amazon Alexa and Google Assistant.

    Where is it used?

    • Electric water heaters
    • Electric heaters and infrared panels
    • Sauna stoves up to 5.5 kW
    • Circuits of a single room or zone
    • Workshop equipment
    • Country houses and rental properties

    Use by need

    For homeowners.
    See how much a water heater or heater uses and control it by phone or schedule.
    For electricians.
    Up to 25 A directly – often no separate contactor is needed.
    For rental property managers.
    Monitoring of room or appliance consumption and remote disconnection.

    Practical use

    If a 3 kW water heater should heat only at the night tariff, install POWR3 in the water heater supply circuit, set a night schedule in the eWeLink app and monitor consumption in the history.

    Pros

    • 25 A / 5500 W load
    • Power, current and voltage metering
    • History up to 100 days with CSV export
    • Protective disconnection
    • Home Assistant integration

    Cons / limitations

    • Not MID certified – not suitable for billing
    • 2.4 GHz Wi-Fi only
    • Not DIN rail mounted
    • Remote control requires internet

    Safety and installation notes

    • Before installation switch off the power and verify that no voltage is present
    • Installation must be carried out by a qualified electrician
    • Select the cable cross-section for 25 A
    • Protect the circuit with a suitable circuit breaker and, where required, a residual current device
    • Install in a dry room and tighten the terminals

    Suitable when you need:
    • to control a high-power appliance from the phone
    • to monitor the consumption of a water heater or heater
    • to disconnect the load automatically in case of a fault
    Check before use:
    • the load current (up to 25 A)
    • the cable cross-section and protection
    • the mounting location (not a DIN rail)
    • the Wi-Fi signal at the installation point
    Important reminder: POWR3 is neither a protective device nor a billing meter – it does not replace a circuit breaker, a residual current device or a MID certified meter.
