Shelly EM Gen3
- Energy monitoring:
Supports up to 2 current transformers (CTs) for precise, non-contact measurement.
Ideal for monitoring appliances, circuits, or solar panel production.
- Connectivity:
Wi-Fi for remote access and automation.
Bluetooth for easy setup and pairing.
- Relay control: Includes a single dry contact relay to control external loads (e.g., shut off during overload).
- Data storage: Internal memory stores up to 10 days of minute-resolution logs.
- Integration:
Works with Shelly Cloud, MQTT, HTTP, WebSocket, and RPC protocols.
Compatible with Alexa, Google Home, and other smart home platforms.
- Retrofit design: Fits into standard electrical boxes, behind outlets or switches.
- Advanced features: Overload protection, scheduling, and automation triggers.
Solar monitoring: Perfect for tracking solar panel production and household consumption simultaneously.
Overload protection: Use the dry contact relay to disconnect loads when consumption exceeds safe limits.
Automation flexibility: Combine with Shelly relays or plugs to trigger actions based on energy usage (e.g., turn off heater if power spikes).
Local & cloud control: Works standalone on Wi-Fi or integrated into cloud services for remote access.
Data analysis: Export logs for energy efficiency audits or billing optimization.
CT clamps required: Device cannot measure consumption without compatible current transformers.
Installation safety: Should be installed by a qualified electrician to avoid wiring hazards.
Load compatibility: Ensure relay is used only within supported voltage/current limits.
Wi-Fi dependency: Remote monitoring requires stable Wi-Fi; without it, only local logging works.
Indoor use: Not waterproof — must be installed in a protected enclosure if used outdoors.
