Shelly EM Measure and Control Everything

Energy meter and control with WiFi power.

Individually monitor the consumption of household appliances, electrical circuits and office equipment (lighting, power lines, security systems, heating and cooling, etc.).

Whole house consumption or electricity generation from solar collectors with the world's only energy meter with contactor monitoring function.

Small size packed with features

Cleverly designed to fit most standard electrical and switch boxes.

Shelly EM is smaller than two cookies stacked together.

At least one current measuring terminal is required for operation,

such as Shelly Current Transformer 120A and 50A

Wifi connected

Shelly EM can connect directly to any Wi-Fi network, no HUB required or can function as an Access Point.

Power supply

Shelly EM is compatible with all major international voltage standards.

Double power measurement

Shelly ЕМ can monitor real-time energy consumption for 2 circuits simultaneously (up to 120A each).

Mobile app control

Turn devices on/off directly from your smartphone or tablet.

You can manage Shelly EM output from the Shelly app , MQTT or Rest API.

Counter check

Shelly EM has an integrated 2A 230V 50/60Hz relay output for meter control.

Over-consumption and over-energy protection

Shelly EM can automatically switch off the entire circuit if consumption or energy (prepaid energy option) reaches the set limit.

Protection against excessive consumption and excess energy

Shelly EM can notify and/or automatically shut down the circuit if consumption or energy reaches the preset limit.

Embedded web server

Turn on/off and monitor consumption directly from its interface without the need for any additional controller or hub, thanks to the embedded web server.

Sunrise/sunset times

Shelly EM can turn on/off automatically based on sunrise and sunset times.

Weekly programming

Create custom daily schedules for your devices.

Compatible with

Android, iOS, Amazon Alexa , Google Assistant and home automation servers using MQTT, CoAP and REST APIs.

Easily make your Arduino project come alive and usable in your automation project.

Energy efficiency

Many homes and buildings use more energy than necessary. This leads to inefficiencies, wasted energy and ultimately, rising monthly bills.

Shelly solutions for home automation and structures can help you reduce energy waste and

monthly bills up to 30% through a 3-step energy efficiency cycle.

For Developers

Shelly EM comes with a programming/debugging header that can be used to flash

of alternative firmware on the device. It has an ESP8266 inside, with a 2MB flash chip.

You need a USB to UART adapter and a reliable 3.3V with a drive capacity of at least 350mA.

Features Shelly EM

• Two independent measurement channels
• A contactor control (or load up to 2A)
• 365 days of internal memory in case a WLAN is not available
• Voltage measurement and configurable alarm message
