WHY PRO EM-50?
Your intelligent solution for precise energy monitoring and control
Shelly Pro EM-50A is a DIN-mountable single-phase energy meter with integrated switch for contactor control. With 1% accuracy in measuring active energy, Shelly Pro ЕМ-50 can be used to monitor consumption and control any household appliances, circuits and office equipment. The device has a data history of 60 days at 1-minute intervals. In addition, its scripting functions enable the execution of complex scenes and offer more comprehensive monitoring options.

WLAN, LAN and Bluetooth connectivity:
Simultaneous use of Ethernet and WLan. MQTT, incoming and outgoing WebSocket, UDP, mTLS support.

Accuracy class B (active energy):
Shelly Pro EM-50 has a measurement accuracy of 1%.

Integrated switch:
2 A dry contact switch for contactor control

MODBUS support:
Enables quick and easy use in existing industrial plants.

Power measurement:
Monitors two independent channels on the same phase

Scripting:
Shelly Pro EM-50 fully supports mjS scripting, so you can create more features and functions.

Application examples:

Perfect for SME owners
If you own a small or medium-sized business, you have probably struggled with excessive energy consumption at some point. Some machines and appliances are switched on all the time. With the Shelly PRO EM-50, you can measure and reduce consumption with maximum precision by switching off consumers such as water dispensers, laminators and lighting at night. The smart device can also be used for preventive measurements by monitoring the abnormal behaviour of HVAC systems, air compressors, refrigerators and other appliances.

Renewable energy ecosystem at home
If you have a photovoltaic (PV) system at home, Shelly PRO EM-50 can help you measure the grid and imported energy from renewable sources. It also has a configurable load control that allows you to redirect excess energy from renewable sources to electronic devices in your home and optimise your energy consumption. For example, you can use the Shelly PRO EM-50 to charge your car or household appliances when your PV system is providing excess energy.

Shelly Smart Control is here!
An app to control your rooms, your energy consumption and your expenses. Customise your dashboards, get detailed consumption reports and keep track of your energy bills.

Full compatibility:
Shelly devices are compatible with Alexa, Google Home, Android and iOS. Together with the voice assistant, you can control Shelly devices with your voice!
