APPLICATION EXAMPLES

DEVICE CONTROL AND MONITORING

Forecast your monthly costs and plan your expenses better! Automate the electrical devices in the restaurant and monitor their energy consumption from anywhere – wherever you are. Shelly Pro 4PM notifies you if a device is left on outside the restaurant's opening hours and prompts you to turn it off to avoid electricity consumption. Additionally, you can set smart schedules and have Shelly cut power to all unused electrical devices during the night and turn them back on shortly before work begins.

LOAD SHEDDING

Keep track of how much energy your solar panels and wind turbines generate and save effortlessly by monitoring your consumption with Shelly Pro 4PM. Connect Shelly Pro 4PM to your devices and use real-time information from Shelly 3EM about how much energy has been generated and consumed. If you need to save energy, Shelly Pro 4PM can automatically turn off connected devices that are not necessarily needed in your home.

TEMPERATURE CONTROL FOR BETTER PRODUCTIVITY

Studies show that employee productivity decreases when there are temperature fluctuations in the office. The building's cooling and heating systems should adapt to the changing temperatures throughout the seasons.

Connect Shelly Pro 4PM with the motorized electric valves in your water distribution box and control your heating and cooling efficiently. Smart schedules combined with temperature and humidity sensors as well as precise weather data provide dynamic control of the heating system, ensuring an optimal indoor climate in the office.

AUTOMATION OF COMMON AREAS FOR EFFICIENT ENERGY USE

Reduce unnecessary monthly costs with Shelly's smart lighting solutions. Shelly Pro 4PM can measure and control four separate lighting circuits, giving you full control over common areas like halls, garages, and storage rooms, whose lights are usually always on. Now you can make them energy-efficient with the integrated scheduling and scripting features of Shelly Pro 4PM. To fully automate your premises, add Shelly Motion2 to automatically turn on the lights when someone enters. The preset smart timer turns the lighting off again as soon as the rooms are empty.
