Shelly Pro 3EM-3CT63, Wi-Fi & Bluetooth
Product Description
The Shelly Pro 3EM-3CT63 Wi-Fi & Bluetooth Module is a DIN-rail mountable 3 phase module designed to add remote energy monitoring over AC loads up to 63A and include them into a smart home network. This high voltage dry contact energy monitoring module supports resistive, capacitive, and inductive loads, sharing real-time energy usage with a Wi-Fi or Bluetooth compatible smart home network. The Pro 3EM-3CT63 is installed in a standard electrical breaker box and requires a neutral wire for operation. Dual connectivity options simplify network installation with Wi-Fi (or LAN) for seamless integration into your local network and Bluetooth for easy, out-of-the-box configuration and connection with your mobile device and nearby Shelly Bluetooth devices or Shelly devices acting as Bluetooth gateways. Use the Shelly Smart Control mobile application, or the mobile app of a connected Wi-Fi hub or controller, to program the Pro 3EM-3CT63 to switch On/Off in response to preprogrammed triggers or at scheduled time of day.
- DIN-mountable Wi-Fi, LAN, & Bluetooth module measures and reports energy consumption in real-time of 3 channels
- Measures up to 260V, 2A switching current, 63A power per phase within 1% accuracy in real time
- Measure energy consumption of large appliances, computers, EV Chargers, or grouped devices
- Remotely monitor the Pro-3EM 400 and connected loads from the Shelly Smart Control app, no smart hub required
- 4 Quadrant measurement with optical pulse indication of energy usage
- Stores up to 60 days of energy usage data on local memory in 1 minute intervals
- Built-in temperature sensor and overheating protection shuts down the Pro 3EM-3CT63 when unsafe or rapid changes in temperature are detected nearby
- Enhanced with HTTP/HTTPs webhooks, Pro 3EM-3CT63 devices can easily work with 3rd party electrical equipment and automation systems and follow 20 actions per week, no hub or cloud server required
Why You Would Use This Product:
The Shelly Pro 3EM-3CT63 is an ideal solution for both DIY enthusiasts and professional installers looking to upgrade a residential or commercial space with accessible smart technology. In a home, you can install it in your circuit breaker box to monitor the energy usage of large appliances, home offices, or server rooms, with Wi-Fi allowing control over the internet and Bluetooth assisting in setup and acting as a gateway for Shelly Bluetooth devices. For a commercial application, mount multiple Shelly Pro 3EM-3CT63 units on a DIN rail within an office's main electrical panel to monitor the status and energy consumption of lighting circuits in different zones. Its ability to integrate with Wi-Fi compatible smart home and voice assistant ecosystems means you can easily incorporate it into your existing setup for voice control and automated scenes.
