Sonoff MINI PM Zigbee Power Meter (Non-Switch)

One circuit, the line wired through its L and L Out terminals

Inline measurement through the module's own terminals, with no current transformer involved

SONOFF publishes measurement ranges (100-240 V, 0-16 A, 0-3840 W) but no accuracy figure for this model, on the product page or in the knowledge center

Rated 100-240V~ 50/60Hz on a single line, so a 120/240 V split-phase service is out of scope

SONOFF's FAQ confirms bi-directional metering and lets the app record generation as a negative value, which is what makes a balcony solar circuit readable | Zigbee2MQTT exposes the export side separately as output_energy_today, output_energy_month and total_output_energy

SONOFF documents real-time voltage, current, power and accumulated energy, and the Zigbee2MQTT expose list carries no power factor attribute

The Wi-Fi version of this meter is a separate model, the MINI-1GP

SONOFF's own comparison lists the connectivity as Zigbee 3.0/BLE, and the knowledge center documents a Bluetooth pairing mode on the button, available once the meter is paired with a Zigbee gateway

Zigbee 3.0 over IEEE 802.15.4 on an EFR32MG21, and it joins as a Zigbee router, so it repeats the mesh for other devices | SONOFF rates the link to the gateway at 180 metres by default and 250 metres with Turbo mode on

SONOFF advertises real-time voltage, current and power but publishes no reporting interval, and the Zigbee2MQTT converter does not state one either

Cloud storage of up to one year of energy data, and an offline device keeps recording locally and re-syncs once it reconnects. SONOFF's own specs tab states 180 days in one paragraph, against one year in the knowledge center, on the feature graphic and on the Amazon listing.

Custom currency and electricity rate, with the bill broken down in charts in the eWeLink app

Fixed or time-of-use tariffs, with consumption and cost shown per pricing period

Energy data and electricity bills export to a spreadsheet from the app

Overcurrent, overpower, overvoltage and undervoltage thresholds, plus a run completion alert with a delay that ignores a washer's fill and drain dips, and a maintenance reminder based on accumulated runtime above a power threshold | Zigbee2MQTT exposes the same thresholds as a settable power_protector object and reports the overload alarm

SONOFF states this is a non-switch product that does not support device control, and its own comparison leaves the On/Off row empty for this model

With no relay it can raise a threshold alert or trigger a separate smart device to cut the load, but it cannot shed the circuit it measures

Smart Scene in eWeLink, and SONOFF's hub table keeps scenes working through Zigbee2MQTT, ZHA and SmartThings as well

Indoor concealed installation: it wires into live and neutral behind a socket or inside an embedded box, and SONOFF recommends a wall box at least 60 mm deep

Indoor concealed installation only, with no rail clip

SONOFF's platform table lists Google Home for this model, reached by adding the meter to eWeLink through a SONOFF Zigbee gateway and linking the account, or through a SONOFF Matter bridge

SONOFF's platform table lists Alexa three ways for this model: through eWeLink account linking, through a SONOFF Matter bridge, or directly on an Echo with a built-in Zigbee hub

SONOFF's platform table marks Apple Home as available only via a Matter bridge (ZBBridge-U, iHost or eWeLink CUBE with a SONOFF Zigbee dongle). Apple Home has no Zigbee radio of its own.

SONOFF's compatible hub table lists SmartThings through the Aeotec Smart Home Hub (V3), which pairs the meter as a standard Zigbee device and reads power; a SmartThings driver has to be imported manually to see the energy figures

Zigbee2MQTT supports this exact model from version 2.11.0 and exposes power, current, voltage, daily, monthly and total energy in both directions, the overload alarm, the protection thresholds, the network indicator and turbo mode | ZHA works through the setup script SONOFF publishes in its knowledge center while the native support pull request is still pending review

The meter itself is Zigbee, not Matter: SONOFF republishes it into Matter through its own bridges (ZBBridge-U, iHost, eWeLink CUBE with a SONOFF Zigbee dongle).

A Zigbee end device with no IP stack, so there is nothing on the module to call directly; the API belongs to whichever gateway hosts it

No native MQTT, though Zigbee2MQTT republishes the readings

Nothing runs on the module itself: it is configured from the eWeLink app or from the Zigbee gateway
