Description

The Shelly EM Gen3 is a two‑phase energy meter that delivers measurement accuracy within 1% and supports both cloud-based and local data storage. It connects directly to Wi-Fi without the need for an additional hub, and thanks to its Bluetooth capability, it can be added to an existing Shelly network quickly and effortlessly.

This model comes with one 50A current clamp for monitoring circuits up to 50A and can be integrated into smart schedules or automated scenes across other Shelly devices—helping track energy consumption and disable non-essential loads when a predefined usage limit is reached.

Building on the previous-generation Shelly EM, the EM Gen3 features an upgraded, in‑house‑designed chip with 8MB of memory, providing smoother performance and a more responsive user experience.
