Set custom scenarios by combining Shelly Pro 1 with your other Shelly devices. Endless applications CONTROL ROOM TEMPERATURE IN COMMUNAL AREAS In guest rooms, reception areas, restaurants or meeting rooms, a comfortable temperature contributes significantly to the well-being of guests and employees. However, it is difficult to maintain an optimal temperature without wasting energy. To achieve this, the cooling/heating systems in hotels should adapt to changing temperatures over the course of the seasons. Use Shelly Pro 3 to control the motorized valves in your water distribution box and control heating, cooling or other motorized valves in your building. Intelligent schedules combined with temperature and humidity sensors as well as precise weather data ensure dynamic control of the heating system and thus an optimal indoor climate. LIGHT AUTOMATION OF COMMON SPACES Reduce unnecessary monthly costs with Shelly's intelligent lighting solutions. Shelly Pro 3 can control three separate lighting circuits, giving you full control of common areas such as halls, garages and storage rooms where the lights are usually on all the time. Now you can make them energy efficient with Shelly Pro 3's built-in scheduling and scripting features. To fully automate your space, add Shelly Motion2 to automatically turn on the lights when someone enters. The preset intelligent timer turns the lights off again as soon as the premises are empty again. CONNECTIVITY Wi-Fi
