Key differences between Meross EM16P and NodOn Zigbee Smart Energy Monitor

A summary of selected recorded differences between these energy monitors. Check the full specification table below for details and conditions.

Feature differences among your selected devices

2.4 GHz Wi-Fi (connectivity): Meross EM16P — Yes; NodOn Zigbee Smart Energy Monitor — No (The 2.4 GHz radio is Zigbee (IEEE 802.15.4), not Wi-Fi).
Data Export (data monitoring): Meross EM16P — Yes (Exportable hourly reports); NodOn Zigbee Smart Energy Monitor — No (Not a native NodOn feature. Exporting the readings is a function of the home automation platform.).
Energy Cost Tracking (data monitoring): Meross EM16P — Yes; NodOn Zigbee Smart Energy Monitor — No (Not a native NodOn feature. Any cost figure is calculated by the home automation platform from the readings.).
Usage Alerts (data monitoring): Meross EM16P — Yes (Custom alerts for usage spikes and threshold breaches); NodOn Zigbee Smart Energy Monitor — No (Not a native NodOn feature. Usage alerts are built in the home automation platform from the readings.).

Specifications to check side by side

Zigbee (connectivity): Meross EM16P — No; NodOn Zigbee Smart Energy Monitor — Zigbee Hub required (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).
Power Supply (installation): Meross EM16P — Mains (breaker panel); NodOn Zigbee Smart Energy Monitor — Mains (110-240 V).
Accuracy (metering): Meross EM16P — ±2%; NodOn Zigbee Smart Energy Monitor — ±1% (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).
Monitored Circuits (metering): Meross EM16P — 18; NodOn Zigbee Smart Energy Monitor — 1 (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).

Split Phase

Meross EM16P: Yes
NodOn Zigbee Smart Energy Monitor: No
Catalog note
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
