NodOn Zigbee Smart Energy Monitor vs Sonoff MINI PM Zigbee Power Meter (Non-Switch)

The 2.4 GHz radio is Zigbee (IEEE 802.15.4), not Wi-Fi

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

Zigbee 3.0 certified, 2.4 GHz, maximum radio power +10 dBm, so it joins an existing Zigbee network and needs a compatible coordinator or gateway | NodOn lists Home Assistant, SmartThings, Jeedom and Zigbee2MQTT as compatible gateways for this model

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

Through the compatible Zigbee gateway or Home Assistant, not on the device itself

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

No switching output: the meter measures only and has no relay to cut a load

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

Installed in-line inside the electrical panel on an existing circuit, next to the upstream protection device

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

Zigbee2MQTT supports this exact model, the SEM-4-1-00, and exposes power, voltage, current, AC frequency, power factor, apparent power and both consumed and produced energy | NodOn also lists Home Assistant among the compatible gateways for this model | Works with Home Assistant through ZHA and through Zigbee2MQTT.

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

NodOn lists SmartThings among the compatible gateways for this model, so it pairs with a SmartThings hub as a standard Zigbee 3.0 device

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

A Zigbee end device with no IP stack and no documented serial interface, so there is nothing on the module itself to call directly; the data path belongs to whichever gateway hosts it

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

Nothing runs on the module itself: it is paired and configured from the Zigbee gateway, and it has only a status LED and a reset/pairing button

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

No native MQTT, though Zigbee2MQTT republishes the readings

No native MQTT, though Zigbee2MQTT republishes the readings

Bidirectional measurement reports consumption and production separately, which is what makes solar self-consumption and export readable | Zigbee2MQTT exposes the consumed total as energy and the production side as produced_energy for this exact model

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

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

Rated up to 63 A directly on the circuit, without a current transformer

One 1P+N circuit: the line is wired through the meter's own terminals and the neutral passes alongside, so it meters a single circuit up to 63 A

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

Rated 110-240 V AC 50/60 Hz as a 1P+N single-phase meter, so a 120/240 V North American split-phase service with two hot legs is out of scope

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