Key differences between Shelly EM 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.
Feature differences among your selected devices
- Load Management (features): Shelly EM Gen4 — Yes (Switch a contactor from consumption thresholds or schedules); Sonoff MINI PM Matter Over WiFi Power Meter (Non-Switch) — No (With no relay it can raise a threshold alert but cannot shed the load itself).
- Relay Output (features): Shelly EM Gen4 — Yes (Dry contact rated 2 A at 240 V for contactor control); Sonoff MINI PM Matter Over WiFi Power Meter (Non-Switch) — No (SONOFF states this is a non-switch product that cannot control the load it measures).
- Power Factor (metering): Shelly EM Gen4 — Yes (Active and apparent power and energy, plus power factor); Sonoff MINI PM Matter Over WiFi Power Meter (Non-Switch) — No (SONOFF documents real-time voltage, current, power and accumulated energy, with no power factor reading).
Specifications to check side by side
- Zigbee (connectivity): Shelly EM Gen4 — Zigbee Hub required (Zigbee 802.15.4 and acts as a Zigbee 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 Gen4 — 30 days (At least 30 days of 1-minute records stored 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 Gen4 — Mains (110-240 V); Sonoff MINI PM Matter Over WiFi Power Meter (Non-Switch) — Mains (100-240 V).
- Apple Home (integrations): Shelly EM 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
- 6 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.
