Minimal dimensions of 29 × 34 × 16 mm allow installation where other devices won’t fit—such as behind a socket or in a box near the electricity meter. Shelly EM Mini Gen4 measures voltage, current, power, and energy with ±1% accuracy and supports bidirectional measurement for homes with photovoltaics.
Thanks to support for Wi‑Fi (including ax), Zigbee, and Bluetooth, it works standalone on the local network, via Shelly Cloud, and in automations through MQTT, HTTP/HTTPS (WebHooks), WebSocket, UDP, and Matter. It features a built‑in web interface, scheduling, scripting (Shelly Script), and in BLE Gateway mode it relays data from Shelly BLU sensors. It can also extend Wi‑Fi and Zigbee range.
Main advantages:
- Compact design for easy installation in distribution boards and boxes
- Accurate measurement ±1%, including consumption and production
- Wide connectivity: Wi‑Fi, Zigbee, Bluetooth, Matter
- Local operation, cloud, and open integrations (MQTT, WebHooks, Home Assistant, Tuya, etc.)
- Data export to CSV/JSON, memory of at least 10 days (1‑min interval)
