Dual‑channel SHELLY energy meter with Wi‑Fi/LAN. Real‑time monitoring, 60‑day logging, TLS, MQTT/HTTP, DIN rail. Precise voltage and current measurement.
99,90 €
Advanced dual‑channel single‑phase energy meter for precise consumption monitoring. Offers Wi‑Fi/LAN connectivity, real‑time measurements (voltage, current, active and apparent power, power factor), and 60‑day internal memory. Integrates via MQTT/HTTP/WebSocket, uses secure TLS transport, mounts on a DIN rail, and includes a built‑in web interface for easy setup.
SHELLY Pro EM‑50 gives you full control over energy consumption in homes and commercial sites. Dual‑channel single‑phase metering with accuracy up to ±1% lets you monitor voltage 100–260 V, current 0–50 A (via CT), active and apparent power, and power factor in real time. Thanks to non‑volatile memory, you have a 1‑minute‑resolution history for up to 60 days.
The device works reliably locally over LAN and Wi‑Fi, with simple setup via the built‑in web interface. For smart‑home and industrial integrations it supports MQTT, HTTP, and WebSocket; all incoming connections are protected by TLS. Scripting and webhooks are supported for advanced automation and easy data export.
