Sonoff MINI PM Matter Over WiFi Power Meter (Non-Switch) vs Sonoff MINI PM Zigbee Power Meter (Non-Switch)

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

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

Up to one year of energy data, and going offline does not interrupt the recording

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

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

Fixed or time-of-use pricing, with consumption shown per rate band

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

Overcurrent, overpower, overvoltage and undervoltage thresholds, plus a run completion alert and a maintenance reminder based on accumulated runtime

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

Quick Scenes in eWeLink, and its readings drive automations in Home Assistant

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

With no relay it can raise a threshold alert but cannot shed the load itself

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

SONOFF states this is a non-switch product that cannot control the load it measures

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

Wires into live and neutral behind a socket or inside a junction box, and SONOFF recommends a wall box at least 60 mm deep

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 flush mounting only, with no rail clip

Reached by adding the meter to eWeLink and linking the account, the path SONOFF documents for this model

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

Reached by adding the meter to eWeLink and linking the account, the path SONOFF documents for this model

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 gives Home Assistant two routes, Matter and MQTT discovery, and both carry the voltage, current, power and energy readings

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

Reached through eWeLink account linking, and SONOFF notes SmartThings also reads the power consumption figures

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

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

Bi-directional metering separates what the load consumes from what a balcony solar array produces, which the app can record as a negative value

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

Inline measurement, no current transformer involved

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

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

SONOFF documents real-time voltage, current, power and accumulated energy, with no power factor reading

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

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