Key differences between Shelly Pro EM-50 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
- Ethernet (connectivity): Shelly Pro EM-50 — Yes; Sonoff MINI PM Matter Over WiFi Power Meter (Non-Switch) — No.
- Load Management (features): Shelly Pro EM-50 — Yes (Configurable load control to divert surplus PV production); 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 Pro EM-50 — Yes (Integrated switch with potential-free contacts, 2 A at 240 V); 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).
- Din Rail Mount (installation): Shelly Pro EM-50 — Yes (One DIN module wide); Sonoff MINI PM Matter Over WiFi Power Meter (Non-Switch) — No (Indoor flush mounting only, with no rail clip).
Specifications to check side by side
- Other (connectivity): Shelly Pro EM-50 — Modbus; Sonoff MINI PM Matter Over WiFi Power Meter (Non-Switch) — No.
- Data History (data monitoring): Shelly Pro EM-50 — 60 days (At least 60 days of 1-minute data 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 Pro EM-50 — Mains (100-260 V); Sonoff MINI PM Matter Over WiFi Power Meter (Non-Switch) — Mains (100-240 V).
- Apple Home (integrations): Shelly Pro EM-50 — 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
- 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.
