Shelly Pro 3EM has a measurement accuracy of 1%.
Allows for easy and fast deployment in existing industrial installations.
Simultaneous Ethernet and Wi-Fi usage. MQTT, inbound and outbound WebSocket, UDP, mTLS support.
Monitors mono-phase electrical systems with up to 3 points simultaneously. Fast notifications and at least 60 days of 1-minute records storage.
Shelly Pro 3PM fully supports mjS scripting, allowing you to create further features and functionalities.
Endless use applications
Shelly Pro 3EM brings support for MODBUS for voltage, current, power, and energies. You can accurately sample your energy usage and instantaneous values of voltage, current, and power. Our new firmware platform allows for custom implementation that can report as fast as every 100ms to your infrastructure.
Monitor your home, office, or factory, and avoid additional expenses or drops in voltage that can damage your appliances and devices. Shelly Pro 3EM can calculate 2-way consumption: produced and used energy for each of the three phases. The device can be configured to measure three separate circuits of a mono-phase electrical system. View the quality of your electricity network regarding active power, reactive power, voltage, and power factor.
Thanks to Shelly Pro 3EM's scripting functionalities and webhooks, you can now easily control other Shelly or Wi-Fi devices on your local network. Use these capabilities to set exact parameters for heating, cooling, or electric vehicle charging based on PV production and have your devices automatically shed power usage. All these work without using a cloud.
