EXAMPLES

DEVICE CONTROL AND MONITORING

Forecast your monthly costs and plan your expenses better! Automate the electrical appliances in the restaurant and track their energy consumption from anywhere – wherever you are. Shelly Pro 4PM lets you know if a device is forgotten and left in operation outside of the restaurant's opening hours; and prompts you to turn it off to avoid power consumption. In addition, you can set smart schedules and have Shelly turn off the power for all unused electrical appliances during the night and turn them back on just before you start work.

LOAD DROP

Keep track of how much energy your solar panels and wind turbines are generating, and save effortlessly by controlling your consumption with Shelly Pro 4PM. Connect Shelly Pro 4PM to your devices and use Shelly 3EM's real-time information on how much energy has been generated and consumed. If you need to save energy, Shelly Pro 4PM can automatically turn off connected devices that aren't essential in your home.

TEMPERATURE CONTROL FOR BETTER PRODUCTIVITY

Research shows that employee productivity decreases when there are temperature fluctuations in the office. The cooling and heating systems in the building should adapt to the changing temperatures over the course of the seasons.

Connect Shelly Pro 4PM to the motorized electric valves in your water distribution box and control your heating and cooling efficiently. Intelligent schedules in combination with temperature and humidity sensors as well as precise weather data ensure dynamic control of the heating system and thus an optimal indoor climate in the office.

AUTOMATION OF COMMON AREAS FOR EFFICIENT USE OF ENERGY

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