Key differences between Refoss EM01P 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

Time Of Use Rates (data monitoring): Refoss EM01P — No; Sonoff MINI PM Matter Over WiFi Power Meter (Non-Switch) — Yes (Fixed or time-of-use pricing, with consumption shown per rate band).
Breaker Panel Install (installation): Refoss EM01P — No (Magnetic mount on the meter face, no wiring and no panel work); Sonoff MINI PM Matter Over WiFi Power Meter (Non-Switch) — Yes (Wires into live and neutral behind a socket or inside a junction box, and SONOFF recommends a wall box at least 60 mm deep).
Smart Meter Port (installation): Refoss EM01P — Yes (Optical head for SML and IEC 62056 smart meters, some need a PIN from the utility); Sonoff MINI PM Matter Over WiFi Power Meter (Non-Switch) — No.
Alexa (integrations): Refoss EM01P — 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); 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).

Specifications to check side by side

Data History (data monitoring): Refoss EM01P — 5 years (Local storage plus free cloud, daily data kept up to 5 years); 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): Refoss EM01P — USB; Sonoff MINI PM Matter Over WiFi Power Meter (Non-Switch) — Mains (100-240 V).
Apple Home (integrations): Refoss EM01P — No; 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
