Tuya Smart WiFi alarm
Secure payments
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.
