Shelly Pro 3EM

Overview:

Shelly Pro 3EM is a Wi-Fi-operated DIN-mountable 3-Phase Energy Meter with Wi-Fi, Bluetooth, and LAN connectivity. With an active energy measurement accuracy of 1%, Shelly Pro 3EM can be used to monitor the consumption of home appliances, electric circuits, and office equipment individually. It features 60 days of on-device historical data with a 1-minute resolution for each phase. Additionally, its scripting functionalities allow for the execution of complex scenes and provide broader monitoring abilities.

Features:

• No HUB required.
• Measure capacitive and inductive load types of active imported and exported energies
• Designed to fit in most standard electrical boxes and switches.
• It can be integrated to work with all other Shelly devices.
• Shelly Pro 3EM has a measurement accuracy of 1%.
• Compatible with Android, iOS, Amazon Alexa, Google Assistant, and home automation servers using MQTT, CoAP, and REST API.
