Key differences between Sonoff MINI PM Matter Over WiFi Power Meter (Non-Switch) 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

Load Management (features): 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); SONOFF POWCT — Yes (Overload protection switches the contactor off above the configured threshold).
Relay Output (features): 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); SONOFF POWCT — Yes (Dry contact rated 2 A for contactor control).
Din Rail Mount (installation): Sonoff MINI PM Matter Over WiFi Power Meter (Non-Switch) — No (Indoor flush mounting only, with no rail clip); SONOFF POWCT — Yes.
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); SONOFF POWCT — No (eWeLink LAN mode keeps control working without internet, but there is no documented device API).

Specifications to check side by side

Data History (data monitoring): 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); SONOFF POWCT — 6 months (Hour-by-hour records kept on the device, survives power cuts).
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.); 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): 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); 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.).
