Compact smart energy meter for real-time monitoring of connected electrical devices up to 16 A. Matter-certified with Wi-Fi, Zigbee, and Bluetooth connectivity, it fits behind existing switches and outlets for easy retrofit energy monitoring.

Important: Shelly EM Mini Gen4 is an energy meter only. It does not have a built-in relay and cannot switch the connected load on or off.

WHY SHELLY EM MINI GEN4?

Small Size. Smarter Energy Monitoring.

Monitor energy consumption without adding bulky equipment to your electrical installation. Shelly EM Mini Gen4 combines precise energy metering with an ultra-compact form factor designed to fit behind existing switches and outlets.

With Matter certification and multiprotocol connectivity through Wi-Fi, Zigbee, and Bluetooth, it integrates easily into modern smart home environments. Use real-time energy data to understand consumption, identify unusual usage, optimize energy costs, and build smarter automations around how your electrical devices actually operate.

Compact Smart Energy Monitoring

Shelly EM Mini Gen4 is a compact smart energy meter designed to monitor the energy consumption of a connected electrical device or circuit up to 16 A at 240 VAC. Its small form factor makes it particularly useful for retrofit installations behind existing wall switches and sockets where installation space is limited.

Unlike a smart relay, the EM Mini Gen4 is designed specifically for energy measurement. There is no relay inside, so it monitors the connected load without directly switching it on or off.

Understand Where Your Energy Goes

Real-time energy monitoring gives you greater visibility into how electrical devices are performing and how much energy they consume. Use this information to identify unnecessary consumption, understand usage patterns, and make more informed decisions about energy efficiency.

Energy data can also help with preventative monitoring. An unexpected increase in consumption may indicate that an appliance or electrical device is operating less efficiently than usual, helping you identify potential issues before they become more expensive problems.

Matter-Certified Multiprotocol Connectivity

Shelly EM Mini Gen4 supports Wi-Fi, Zigbee, and Bluetooth and is Matter-certified, providing flexibility when integrating it into different smart home environments.

The device can also function as a Wi-Fi and Zigbee range extender and Bluetooth gateway, helping expand connectivity between compatible devices.

More Than Energy Data

Shelly EM Mini Gen4 supports schedules, scenes, local actions, and scripting, allowing its energy measurements to become part of more advanced automation workflows.

It also supports HTTPS, MQTTS, and inbound and outbound WebSockets, making it suitable not only for residential smart homes but also for advanced integrations and custom automation projects.
