Key differences between Sonoff MINI PM Matter Over WiFi Power Meter (Non-Switch) and Zemismart SPM01
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): Sonoff MINI PM Matter Over WiFi Power Meter (Non-Switch) — Yes (IEEE 802.11 b/g/n on 2.4 GHz, from an ESP32-C6); Zemismart SPM01 — No.
- Alexa (integrations): Sonoff MINI PM Matter Over WiFi Power Meter (Non-Switch) — Yes (Reached by adding the meter to eWeLink and linking the account, the path SONOFF documents for this model); Zemismart SPM01 — No (Alexa has no energy meter device type and this meter has no relay to expose as a switch, so a skill has nothing to publish).
- Matter (integrations): Sonoff MINI PM Matter Over WiFi Power Meter (Non-Switch) — Yes (Matter over Wi-Fi: the device carries a Matter QR code and is commissioned by scanning it from a Matter app | Home Assistant is the one Matter controller that accepts it today, because the energy meter device type is not yet handled by the other ecosystems); Zemismart SPM01 — No.
- Local Api (local control): Sonoff MINI PM Matter Over WiFi Power Meter (Non-Switch) — Yes (JSON-RPC 2.0 over HTTP and WebSocket, documented as an open API); Zemismart SPM01 — No.
Specifications to check side by side
- Zigbee (connectivity): Sonoff MINI PM Matter Over WiFi Power Meter (Non-Switch) — No (The Zigbee version of this meter is a separate model, the MINI-ZB1GP); Zemismart SPM01 — Zigbee Hub required (Zigbee 3.0 on a Tuya ZS2S module, works with any certified hub, no Tuya gateway needed).
- Power Supply (installation): Sonoff MINI PM Matter Over WiFi Power Meter (Non-Switch) — Mains (100-240 V); Zemismart SPM01 — Mains (110-240 V).
- Apple Home (integrations): Sonoff MINI PM Matter Over WiFi Power Meter (Non-Switch) — Upcoming platform support (The meter is a Matter over Wi-Fi device, but SONOFF's own platform table marks Apple Home as not yet able to add it: the Home app still does not accept the Matter energy meter device type. Nothing on SONOFF's side is missing, so the meter gets in once Apple supports that type.); Zemismart SPM01 — No.
Information still to confirm
- 12 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.
