Key differences between NodOn Zigbee Smart Energy Monitor and SONOFF POWCT

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): NodOn Zigbee Smart Energy Monitor — No (The 2.4 GHz radio is Zigbee (IEEE 802.15.4), not Wi-Fi); SONOFF POWCT — Yes (External antenna on a lead so it can sit outside the panel).
Data Export (data monitoring): NodOn Zigbee Smart Energy Monitor — No (Not a native NodOn feature. Exporting the readings is a function of the home automation platform.); SONOFF POWCT — Yes (History can be exported to a file from the eWeLink app).
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.); SONOFF POWCT — Yes (Overload alerts and protection thresholds).
Relay Output (features): NodOn Zigbee Smart Energy Monitor — No (No switching output: the meter measures only and has no relay to cut a load); SONOFF POWCT — Yes (Dry contact rated 2 A for contactor control).

Specifications to check side by side

Zigbee (connectivity): 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); SONOFF POWCT — No.
Power Supply (installation): NodOn Zigbee Smart Energy Monitor — Mains (110-240 V); SONOFF POWCT — Mains (100-240 V).
Apple Home (integrations): NodOn Zigbee Smart Energy Monitor — No (Not compatible with Apple Home.); SONOFF POWCT — SONOFF Hub required (SONOFF lists this model among the eWeLink Wi-Fi devices its Matter bridges (Zigbee Bridge Ultra, iHost, NSPanel Pro) publish to Matter, which is how it reaches the Apple Home app.).
Matter (integrations): NodOn Zigbee Smart Energy Monitor — No (The radio is Zigbee 3.0 only, with no Matter certification or Matter path documented for this model); SONOFF POWCT — SONOFF Hub required (The device is not Matter itself: SONOFF lists it among the eWeLink Wi-Fi models its Matter bridges (Zigbee Bridge Ultra, iHost, NSPanel Pro) republish into Matter.).
