    SONOFF POWR316D (POW Elite 16A) is a smart Wi-Fi relay with energy metering and an LCD display, mounted on a DIN rail. It switches loads up to 16 A (3680 W), shows power, voltage, current and kWh, and supports overload limits, schedules, eWeLink, Alexa and Google Assistant.

  • Product description

    Modular | smart | digital energy meter | 16A | 100-240V | DIN | Wi-Fi | SONOFF | POW Elite | POWR316D

    SONOFF POWR316D (POW Elite 16A) is a smart Wi-Fi relay with energy metering and an LCD display, mounted on a DIN rail. It switches loads of up to 16 A and shows power, voltage, current and consumed energy in real time.

    Key idea:
    A panel meter and a remotely controlled relay in one module: you see how much the water heater or heating uses and can switch it off, limit it or control it by schedule.

    How it works

    The load line is connected via POWR316D: phase and neutral at the input, the controlled load at the output. The relay switches the line on or off, and the metering circuit continuously calculates consumption.

    The LCD shows current power, voltage, current and energy, and the eWeLink app shows history and daily and monthly statistics.

    Overload limits, schedules and scenes can be set: e.g. switch off the load when power is exceeded or switch it on during cheaper tariff hours.

    Why choose POWR316D?
    A 16 A relay, accurate metering and a display in the panel make it possible to control larger loads such as water heaters or heating cables and see their costs clearly.

    Main functions

    • Real-time energy metering – power, voltage, current and kWh.
    • LCD display – data visible right in the panel.
    • Remote control – the load is switched on or off from the app.
    • Overload and limit settings – the load is switched off when set limits are exceeded.
    • Schedules and scenes – control by time, tariffs or sensors.
    • Consumption statistics – daily and monthly reports in the app.

    Where is it used?

    • Water heaters and boilers
    • Electric underfloor heating
    • Heat pumps and air conditioners (via a contactor if needed)
    • EV charging lines (by power)
    • Office and commercial lines
    • Solar self-consumption management

    Use by need

    For homeowners.
    You see the costs of the water heater or heating and control them by schedule or a cheaper tariff.
    For electricians.
    A modular DIN solution – meter and relay in one, without separate devices.
    For smart home integrators.
    Energy data and limits allow saving and load management scenarios.

    Practical use

    If a 2 kW water heater should heat only at night, POWR316D is installed in the panel on the heater line, a schedule of 23:00–07:00 is set in the app, and the saved consumption is visible on the display and in the history.

    Pros

    • 16 A relay for larger loads
    • Accurate energy metering
    • LCD display in the panel
    • DIN mounting
    • Overload limits and schedules
    • Alexa and Google Assistant support

    Cons / limitations

    • 2.4 GHz Wi-Fi only
    • A metal panel can weaken the signal
    • Inductive loads may require a contactor
    • Does not replace a circuit breaker

    Safety and installation notes

    • Switch off the main supply and check for voltage before installation
    • Installation must be done by a qualified electrician
    • Protect the line with an appropriate circuit breaker
    • Do not exceed a 16 A load
    • Use a contactor for large inductive loads

    Quick selection guide

    16 A / 3680 W
    Energy metering
    LCD display
    Wi-Fi 2.4 GHz
    DIN rail
    Overload limits
    Suitable when you need:
    • meter and control a water heater or heating
    • limit the load by power
    • control a line by schedule or tariff
    Check before use:
    • the load current and type
    • DIN rail space
    • the Wi-Fi signal in the panel
    • whether a contactor is needed for an inductive load
    Important reminder: POWR316D is not a protective device – the line must be protected by a circuit breaker, and by an RCD in damp areas.

    FAQ

    What is the maximum load?
    Up to 16 A, i.e. about 3680 W at 230 V.
    Does it show consumption on the display?
    Yes, the LCD shows power, voltage, current and energy.
    Can a power limit be set?
    Yes, the load can be switched off when the set limit is exceeded.
    Is it suitable for a water heater?
    Yes, for water heaters and heating cables up to 16 A.
    Will it work in a metal panel?
    Usually yes, but metal doors can weaken the Wi-Fi signal – check the connection.
    How does it differ from POWR320D?
    POWR316D switches up to 16 A, POWR320D up to 20 A; other functions are similar.
