Shelly Pro 3EM-3CT63, Wi-Fi & Bluetooth

Add Wi-Fi, LAN, & Bluetooth Connectivity to A Switch or Outlet

Remotely monitor your appliances, home office, server room, and more through Wi-Fi & Bluetooth connectivity with the Shelly Pro 3EM-3CT63A Wi-Fi & Bluetooth Module! This dry contact energy reader module mounts inside your breaker box to add remote power metering of single or 3 phase inputs on a single electrical load in your home or business. The device reports total consumed energy as well as instantaneous voltage, current, active, and apparent power per phase in real time. Data is stored on local memory that can be retrieved for a period of up to 60 days in 1-minute intervals. The Shelly Pro 3EM-3CT63A supports resistive, capacitive, and inductive loads to allow for most electrical devices to be remotely monitored from your mobile device from the Shelly Smart Control app. It can be used as a standalone device in a local LAN and/or Wi-Fi network, or it can be operated through cloud services through MQTT, HTTP, and WebSocket to be included into a smart automation network.

• DIN-mountable Wi-Fi, LAN, & Bluetooth module measures and reports energy consumption in real-time of 3 channels in a single to triple phase/load
• Measures up to 260V, 2A switching current, 63A power per phase within 1% accuracy in real time; can be used with contactors for bigger loads
• Measure energy consumption of EV Chargers, large appliances, computers, servers, or your whole home/building depending on the size
• Remotely monitor the Pro-3EM-3CT63 and connected loads from the Shelly Smart Control app, no smart hub required
• 4 Quadrant measurement with optical pulse indication of energy usage
• Records 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

Shelly Smart Control App – Everything at Home Connected

Enjoy enhanced home automation control and precise monitoring of your Shelly devices no matter where you are with the Shelly Smart Control app. The app connects to Shelly's cloud service to help you control your connected devices remotely and send notifications for all automated events in your home directly to your smart device. You can easily configure devices and manage their settings individually, or you can create personalized scenes by combining Shelly devices to trigger certain actions in your smart home network. The Shelly Smart Control App supports real-time power metering with power management (PM) devices, smart plugs, and smart bulbs in order to allow you to build complex automation solutions for improved energy efficiency and lower electricity bills. Shelly devices are compatible with other most widely accepted both local and cloud based home automation platforms. A Shelly Smart Control App user account is required to access, include, and control Shelly devices through the Shelly Smart Control application and include your Shelly devices to 3rd party home automation or voice assistant platforms like SmartThings, Amazon Alexa or Google Home.

• Easy Inclusion and Control: Include and name new devices in the Shelly Smart Control app, assign them to the rooms they are located in, and group them into scheduled or automated scenes.
• Custom Dashboard: Create multiple dashboards for quick access to your preferred devices, rooms, and scenes. Issue commands using your dashboards or your preferred voice assistant towards individual devices or a group of devices.
• Smart Scenes: Combine multiple devices into one smart scene with pre-set triggered actions. Lower the lights when the TV is turned on for a "Movie night". Cut off the power and send a notification when a space heater has been left on past 9am while you are "Away at Work".
• Custom Schedules and Timers: Teach your home how to make you more comfortable by setting custom schedules based on your agenda. You can set a Shelly controlled switch to turn on the outdoor lights at 7:00 PM on workdays, or turn on your heater an hour before you return from work.
• Energy Monitoring: An energy consumption panel gives you a detailed view of your live and recorded energy usage from devices controlled by Shelly products. The information is stored in a free cloud and fully accessible to you for further analysis of your energy consumption habits.
• Works with Alexa: Shelly Smart Control is natively compatible with Amazon Alexa.
