These counts describe the available data, not a quality score. More features do not automatically make a better device.
Consider your setup
Confirm which features appear in Apple Home and whether extra hardware or a subscription is needed for your intended use.
Inspect the specificationsConsider your setup
Confirm the exact device type and the features exposed in your chosen platform. Protocol support does not establish feature parity across apps.
Inspect the specificationsYour priorities, side by side
Mark the specifications you care about. Open manufacturer sources for verification scope; fields without citations remain catalog data. Expand notes for other qualifications.

802.11 b/g/n
IEEE 802.11 b/g/n on 2.4 GHz, from an ESP32-C6
The spec sheet lists Wi-Fi only, while the FCC grant authorises a second 2402-2480 MHz transmitter, so the radio is there but SONOFF never documents it as a feature
Zigbee HAN link to the utility meter, not to a home Zigbee network
The Zigbee version of this meter is a separate model, the MINI-ZB1GP
Energy data and electricity bills export to a spreadsheet, from the app and from the local console
1 second data 3 hours, 1 minute data 7 days, 1 hour data indefinitely
Up to one year of energy data, and going offline does not interrupt the recording
Custom currency and electricity rate, with the bill broken down in charts
Fixed or time-of-use pricing, with consumption shown per rate band
Overcurrent, overpower, overvoltage and undervoltage thresholds, plus a run completion alert and a maintenance reminder based on accumulated runtime
Quick Scenes in eWeLink, and its readings drive automations in Home Assistant
Emporia states peak demand, load management and solar-only charging are not supported on this model
With no relay it can raise a threshold alert but cannot shed the load itself
SONOFF states this is a non-switch product that cannot control the load it measures
Plugs into an outlet near the meter, no electrician needed
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 flush mounting only, with no rail clip
Zigbee HAN device that reads the utility's AMI smart meter, only in supported markets
Reached by adding the meter to eWeLink and linking the account, the path SONOFF documents for this model
The meter is a Matter over Wi-Fi device, but SONOFF's own platform table marks Apple Home as not yet able to add it: the Home app still does not accept the Matter energy meter device type. Nothing on SONOFF's side is missing, so the meter gets in once Apple supports that type.
Reached by adding the meter to eWeLink and linking the account, the path SONOFF documents for this model
Community Emporia Vue integration for Home Assistant (HACS), which covers the Vue monitors and the Utility Connect
SONOFF's platform table gives Home Assistant two routes, Matter and MQTT discovery, and both carry the voltage, current, power and energy readings
Matter over Wi-Fi: the device carries a Matter QR code and is commissioned by scanning it from a Matter app | Home Assistant is the one Matter controller that accepts it today, because the energy meter device type is not yet handled by the other ecosystems
Reached through eWeLink account linking, and SONOFF notes SmartThings also reads the power consumption figures
JSON-RPC 2.0 over HTTP and WebSocket, documented as an open API
A local browser console is provided.
Sonoff MINI PM Matter Over WiFi Power Meter (Non-Switch) — manufacturer product description →This product measures energy and does not switch the attached load.
Document check only; not a hands-on test or verification of every regional or firmware variant.
The OpenEdge web console runs on the device and needs no app and no account
MQTT access is listed.
Sonoff MINI PM Matter Over WiFi Power Meter (Non-Switch) — manufacturer product description →This product measures energy and does not switch the attached load.
Document check only; not a hands-on test or verification of every regional or firmware variant.
MQTT is configured from the device itself and is how Home Assistant reads the meter with no cloud in the path
Reads the utility's own AMI meter, so accuracy is the meter's
Solar and net metering
Bidirectional energy metering is supported.
Sonoff MINI PM Matter Over WiFi Power Meter (Non-Switch) — manufacturer product description →This product measures energy and does not switch the attached load.
Document check only; not a hands-on test or verification of every regional or firmware variant.
Bi-directional metering separates what the load consumes from what a balcony solar array produces, which the app can record as a negative value
No current transformers, it reads the meter wirelessly
Inline measurement, no current transformer involved
Whole-house totals from the utility meter, no per-circuit detail
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
Rated 100-240V~ 50/60Hz on a single line, so a 120/240 V split-phase service is out of scope
Light commercial 3-phase service
