Shelly EM Energy Meter

Shelly EM: Finally Get Insight into Your Energy Consumption!

Want to know exactly how much your solar panels are generating or which appliances in your home are the biggest energy hogs? The Shelly EM WiFi Energy Meter gives you detailed, real-time insight into your energy consumption. This compact and smart meter is the perfect solution for monitoring your consumption, saving money, and making your home truly intelligent.

The Shelly EM is a unique energy meter that works over your Wi-Fi network, without the need for a separate hub or controller. It can monitor two circuits or groups simultaneously, each with a load of up to 120A. This makes it ideal for measuring your home's total energy consumption and the output of your solar panels simultaneously, or for monitoring two large-scale consumers separately.

Besides measuring consumption (W) and energy (Wh), the Shelly EM also measures voltage (V) and load quality. All data is stored internally for up to 365 days, so you'll never lose it, even if your Wi-Fi goes down. The built-in contactor control also allows you to control devices via a contactor/relay, for example, to automatically switch off your solar panels in the event of overload or negative energy prices.

Note: This is the tried-and-true classic Shelly EM. A newer Shelly EM Gen3 variant is now also available.

Important: The required current clamps (split-core current transformers of 50A or 120A) are not included as standard and must be ordered separately to use the meter.

Benefits and points of interest:

• Two channels: Measure two groups simultaneously, ideal for solar panels and mains consumption.
• Real-time monitoring: Instant insight into consumption, yield, voltage, and more.
• Built-in switching function: Switch heavy loads via an external contactor.
• No hub needed: Works directly on your 2.4 GHz WiFi network.
• 365 days of data storage: Your measurement history remains securely stored in the device.
• Broad compatibility: Works with the Shelly app, voice assistants, and various smart home platforms.
• Please note: This is the older, discontinued (EOL) model.
• Please note: Power clamps are not included and are essential for operation.
• Not for 3-phase: To measure a 3-phase connection you need the Shelly Pro 3EM.

Compatibility with Smart Home Systems

• Home Assistant: The Shelly EM is known for its excellent integration with Home Assistant. Through the official Shelly integration or via MQTT, all measurements (consumption, energy, voltage) and the switch are fully supported. You can count on seamless and complete functionality.
• Homey: Yes, the Shelly EM is compatible with Homey. An official Shelly app is available for Homey, which makes measurement data and the switching function accessible in your flows.
• Fibaro: Integration with Fibaro is possible, but requires more technical expertise. Because Shelly works over Wi-Fi, the connection must be established via Virtual Devices and API calls. This may not offer the same plug-and-play experience as with Home Assistant or Homey.
