Shelly EM Mini Gen4 - Ultra-Compact, Single-Phase, Wi-Fi and Bluetooth Energy Monitor, Shelly G4 Chip

TheShelly EM Mini Gen4 is the world's smallest energy monitor equipped with professional measurement technology. It is part of the new generation of devices equipped with the high-performance Shelly G4 processor, offering class 1 measurement accuracy and instant response. Thanks to its miniaturised design, it can be easily installed in standard wall sockets, behind outlets or in cluttered electrical panels, allowing you to monitor the consumption of any appliance or circuit without taking up valuable space.

Key Selling Points

• Ultra-Compact Size: Over 35% smaller than standard models, the EM Mini Gen4 fits where no other energy monitor can fit. It is the ideal solution for modernising existing homes without aesthetic changes.

• Accuracy Measurement (Class 1): Although small in size, the device does not compromise on accuracy. It measures essential parameters such as voltage (V), current (A), active power (W) and total stored energy (Wh) with an error of less than 1%.

• New Shelly G4 Hardware: Next-generation processor provides faster data processing, extended internal memory for local data storage (up to 60 days in case of loss of connection) and advanced scripting support.

• Wi-Fi & Bluetooth connectivity: Bluetooth facilitates an initial setup in seconds, while Wi-Fi provides remote control. The device also functions as a Bluetooth Gateway, improving coverage for nearby Shelly BLU sensors.

• Built-in Relay Control (2A): In addition to monitoring, the EM Mini Gen4 features a 2A output relay, which can be used to control an external contactor or visual indicator depending on the level of consumption detected.

• Open and Secure Ecosystem: It supports MQTT, WebSocket and Webhooks protocols, making it easy to integrate into Home Assistant or other professional systems. Features TLS security and internal overheat protection.

Smart Automation Examples

1. Overload Protection: Configures the Shelly EM Mini Gen4 Mini to send an alert or trip a contactor if washer or furnace power consumption exceeds the set safety threshold.

2. Efficiency Monitoring: Identifies appliances that are consuming energy unnecessarily (standby mode) in real time and creates scenarios to switch them off during off hours.

3. Local Energy Audit: View detailed consumption graphs directly on your smartphone to understand the distribution of electricity costs over a day or month.
