NodOn Zigbee Smart Energy Monitor

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

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

Class 1.0 to IEC 61557-12, stated as a 1% tolerance, over a measurement range of 50 mA to 63 A and a base current of 10 A

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

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

Reports voltage, current, active power, apparent power, power factor and AC frequency alongside the energy totals | Zigbee2MQTT exposes power_factor, power_apparent and ac_frequency for this exact model

NodOn advertises real-time monitoring of voltage, current, power and energy but publishes no reporting interval for this model

The meter keeps no history of its own beyond its cumulative energy registers, and NodOn ships no app: retention is whatever the host gateway or Home Assistant keeps

Not a native NodOn feature. Any cost figure is calculated by the home automation platform from the readings.

Not a native NodOn feature. Time-of-use pricing is a function of the home automation platform.

Not a native NodOn feature. Exporting the readings is a function of the home automation platform.

Not a native NodOn feature. Usage alerts are built in the home automation platform from the readings.

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

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

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

NodOn lists load shedding on overconsumption among the meter's uses, driven by its readings | The switching itself is done by the compatible gateway or home automation system, not by the meter, which has no relay

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

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

One 17.8 mm wide DIN module that clips onto the standard 35 mm rail inside the switchboard

Not compatible with Google Home.

Not compatible with Amazon Alexa.

Not compatible with Apple Home.

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

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.

The radio is Zigbee 3.0 only, with no Matter certification or Matter path documented for this model

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

No native MQTT, though Zigbee2MQTT republishes the readings

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
