Key differences between Shelly EM Mini Gen4 and Sonoff MINI PM Matter Over WiFi Power Meter (Non-Switch)
A summary of selected recorded differences between these energy monitors. Check the full specification table below for details and conditions.
Specifications to check side by side
- Zigbee (connectivity): Shelly EM Mini Gen4 — Zigbee Hub required (Zigbee 802.15.4, also acts as a repeater); Sonoff MINI PM Matter Over WiFi Power Meter (Non-Switch) — No (The Zigbee version of this meter is a separate model, the MINI-ZB1GP).
- Data History (data monitoring): Shelly EM Mini Gen4 — 10 days (At least 10 days of 1-minute records on the device); Sonoff MINI PM Matter Over WiFi Power Meter (Non-Switch) — 1 year (Up to one year of energy data, and going offline does not interrupt the recording).
- Power Supply (installation): Shelly EM Mini Gen4 — Mains (110-240 V); Sonoff MINI PM Matter Over WiFi Power Meter (Non-Switch) — Mains (100-240 V).
- Apple Home (integrations): Shelly EM Mini Gen4 — Yes (Via Matter); 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.).
Information still to confirm
- 8 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.
