Key differences between Shelly Pro EM-50 and Sonoff MINI PM Zigbee 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
- 2.4 GHz Wi-Fi (connectivity): Shelly Pro EM-50 — Yes; Sonoff MINI PM Zigbee Power Meter (Non-Switch) — No (The Wi-Fi version of this meter is a separate model, the MINI-1GP).
- Ethernet (connectivity): Shelly Pro EM-50 — Yes; Sonoff MINI PM Zigbee Power Meter (Non-Switch) — No.
- Load Management (features): Shelly Pro EM-50 — Yes (Configurable load control to divert surplus PV production); Sonoff MINI PM Zigbee Power Meter (Non-Switch) — No (With no relay it can raise a threshold alert or trigger a separate smart device to cut the load, but it cannot shed the circuit it measures).
- Relay Output (features): Shelly Pro EM-50 — Yes (Integrated switch with potential-free contacts, 2 A at 240 V); Sonoff MINI PM Zigbee Power Meter (Non-Switch) — No (SONOFF states this is a non-switch product that does not support device control, and its own comparison leaves the On/Off row empty for this model).
Specifications to check side by side
- Other (connectivity): Shelly Pro EM-50 — Modbus; Sonoff MINI PM Zigbee Power Meter (Non-Switch) — No.
- Zigbee (connectivity): Shelly Pro EM-50 — No; Sonoff MINI PM Zigbee Power Meter (Non-Switch) — Zigbee Hub required (Zigbee 3.0 over IEEE 802.15.4 on an EFR32MG21, and it joins as a Zigbee router, so it repeats the mesh for other devices | SONOFF rates the link to the gateway at 180 metres by default and 250 metres with Turbo mode on).
- 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 Zigbee Power Meter (Non-Switch) — 1 year (Cloud storage of up to one year of energy data, and an offline device keeps recording locally and re-syncs once it reconnects. SONOFF's own specs tab states 180 days in one paragraph, against one year in the knowledge center, on the feature graphic and on the Amazon listing.).
- Power Supply (installation): Shelly Pro EM-50 — Mains (100-260 V); Sonoff MINI PM Zigbee Power Meter (Non-Switch) — Mains (100-240 V).
Information still to confirm
- 5 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.
