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 home automation. 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.

• 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.
