Details

SONOFF MINI PM (MINI-1GP) is a compact Wi-Fi Matter-compatible energy meter module designed to measure the electrical consumption of loads up to 16 A on single-phase 100–240 V AC networks. The device is not a switching relay: its primary purpose is to measure voltage, current, instantaneous power, and energy consumption. Thanks to its compact 32 × 29 × 15.9 mm dimensions, it is designed for concealed installation, for example inside an electrical wall box.

The MINI-1GP supports bidirectional energy metering, allowing it to measure both energy consumption and energy fed back into the grid, for example when monitoring the output of balcony solar systems. The eWeLink system provides real-time and historical energy data, charts, and electricity cost calculation, while both energy and cost data can be exported. If the internet connection is interrupted, energy data continues to be stored locally and is synchronized once the connection is restored.

The device supports Matter over Wi-Fi communication, the local OpenEdge web interface, MQTT integration, and a JSON-RPC 2.0 API. It can be integrated into Home Assistant via Matter or MQTT, meaning the manufacturer's eWeLink cloud is not required for local integration. The MINI-1GP is primarily intended for energy metering and energy monitoring applications; a neutral conductor is required for operation.

About SONOFF

SONOFF manufactures smart home devices, relay modules, energy meters, wall switches, Zigbee sensors, control panels, gateways, and various electrical installation accessories. Its product range includes devices using Wi-Fi, Zigbee, Matter, and LAN communication.

SONOFF devices are primarily built around the eWeLink platform, but many products can also be integrated with Home Assistant, Zigbee2MQTT, ZHA, SmartThings, Alexa, Google Home, and other smart home systems. In addition to residential smart home solutions, the manufacturer's range also includes DIN rail-mounted devices, energy monitoring solutions, and products suitable for professional installation.

Key Product Features

Matter compatibility: The MINI-1GP supports the Matter protocol, allowing standardized integration into compatible smart home systems. Support for the Energy Meter device type currently varies by platform.
SONOFF OpenEdge: The device can be managed directly through a web browser on the local network without installing an app or requiring a cloud connection.
Bidirectional energy metering: In addition to energy consumption, power flow in the opposite direction can also be measured, making the device suitable for monitoring energy generated by systems such as balcony solar installations.
Energy data and export: Energy consumption can be monitored on charts, and historical energy data can be exported for further analysis.
Electricity cost tracking: A custom currency and electricity tariff can be configured, allowing the system to calculate and display electricity costs on charts.
Home Assistant integration: Can be integrated into Home Assistant using either Matter or MQTT.
Open API: A JSON-RPC 2.0 API is available over HTTP, WebSocket, and MQTT for accessing device data and integrating it into other systems.

Smart Home Protocols and Platform Compatibility

Wi-Fi: Connects to 2.4 GHz Wi-Fi networks using IEEE 802.11 b/g/n. A separate smart home gateway is not required for eWeLink or local network operation.
Matter over Wi-Fi: The MINI-1GP can be integrated as a native Matter device over a 2.4 GHz Wi-Fi network into compatible Matter systems.
eWeLink: Detailed energy consumption data, charts, cost calculations, data export, and other device settings are available in the eWeLink app.
Home Assistant Matter: Voltage, current, power, and energy data can be exposed to Home Assistant through Matter.
Home Assistant MQTT: The device can also be integrated into Home Assistant using MQTT. In a LAN-only environment, MQTT integration can receive measurement data in real time.
MQTT: An external MQTT connection can be configured through the local OpenEdge interface, allowing measurement data to be sent to a local or third-party system.
HTTP API: The JSON-RPC 2.0-based API is also available over HTTP.
WebSocket: JSON-RPC 2.0 communication and outbound WebSocket connections are supported for integration with external systems.
Alexa, Google Home, Apple Home, and SmartThings: Although the Matter standard is designed for multi-platform compatibility, according to SONOFF's current documentation these platforms do not currently support adding the MINI-1GP because of platform-side limitations related to the Energy Meter device type. This may change with future platform updates.

Smart Features

Electrical Functions

Supply voltage: 100–240 V AC, 50/60 Hz.
Rated current: Up to 16 A.
Electrical system: Designed for single-phase AC networks.
Neutral conductor: A neutral conductor is required for operation of the MINI-1GP.
Energy metering: Measures voltage, current, instantaneous power, and energy consumption.
Bidirectional energy metering: Can measure both energy consumption and exported energy.
Not a switching relay: The MINI-1GP is designed as an energy meter rather than a conventional remotely controlled switching relay. Normal user ON/OFF control of the load is not its intended function.
Wiring: The device has N neutral, L live input, and L Out switched-through live terminals. The measured load receives its live conductor through the device.
Wire cross-section: Supports 0.75–2.5 mm² (18–14 AWG) solid or stranded copper conductors.
Upstream protection: The manufacturer specifies the use of a 16 A rated MCB or an RCBO with overcurrent protection upstream of the MINI-1GP.

Additional Features

Compact size: The 32 × 29 × 15.9 mm enclosure is designed for concealed electrical installation.
OpenEdge local management: The device's web interface can be accessed from the local network using its IP address or the MINI-1GP.local hostname.
Direct AP access: In pairing mode, the device creates its own Wi-Fi access point, allowing direct access to the local web interface.
Local integration: MQTT, HTTP/JSON-RPC, and WebSocket support make it suitable for systems where reliance solely on the manufacturer's cloud is undesirable.
Balcony solar monitoring: Thanks to bidirectional metering, the device can also be used to monitor energy flow from small grid-connected generation systems, provided their electrical parameters remain within the MINI-1GP's rated limits.
Installation: According to the manufacturer's requirements, wiring and maintenance of the device must be carried out by a qualified electrician.
