Key differences between NodOn Zigbee Smart Energy Monitor and Refoss EM16P
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); Refoss EM16P — Yes.
- Bluetooth (connectivity): NodOn Zigbee Smart Energy Monitor — No; Refoss EM16P — Yes.
- 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.); Refoss EM16P — Yes.
- Energy Cost Tracking (data monitoring): NodOn Zigbee Smart Energy Monitor — No (Not a native NodOn feature. Any cost figure is calculated by the home automation platform from the readings.); Refoss EM16P — Yes.
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); Refoss EM16P — No.
- Power Supply (installation): NodOn Zigbee Smart Energy Monitor — Mains (110-240 V); Refoss EM16P — Mains (100-240 V).
- Accuracy (metering): 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); Refoss EM16P — ±2%.
- 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); Refoss EM16P — 18.
Information still to confirm
- 5 of 39 comparison fields lack a resolved value for at least one selected device. Missing information is not evidence that a feature is absent.
- Check the full table and manufacturer documentation before ruling out a device.
These observations are derived from recorded catalog data and have not all been independently verified. Confirm details with the manufacturer before purchasing.
