Key differences between NodOn Zigbee Smart Energy Monitor and Zemismart SPM02

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

Usage Alerts (data monitoring): NodOn Zigbee Smart Energy Monitor — No (Not a native NodOn feature. Usage alerts are built in the home automation platform from the readings.); Zemismart SPM02 — Yes (Alarm messaging on abnormal consumption).
Load Management (features): NodOn Zigbee Smart Energy Monitor — Yes (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); Zemismart SPM02 — No.
Din Rail Mount (installation): NodOn Zigbee Smart Energy Monitor — Yes (One 17.8 mm wide DIN module that clips onto the standard 35 mm rail inside the switchboard); Zemismart SPM02 — No (Fits above or below the protection devices without occupying DIN rail space).
SmartThings (integrations): NodOn Zigbee Smart Energy Monitor — Yes (NodOn lists SmartThings among the compatible gateways for this model, so it pairs with a SmartThings hub as a standard Zigbee 3.0 device); Zemismart SPM02 — No.

Specifications to check side by side

Power Supply (installation): NodOn Zigbee Smart Energy Monitor — Mains (110-240 V); Zemismart SPM02 — Mains (breaker panel).
Monitored Circuits (metering): 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); Zemismart SPM02 — 3 (Three independent measurement channels).
