Endless application possibilities
CONTROL OF ROOM TEMPERATURE IN COMMON AREAS
In guest rooms, reception areas, restaurants, or meeting rooms, a comfortable temperature significantly contributes to the well-being of guests and staff. However, maintaining an optimal temperature without wasting energy is challenging. Cooling/heating systems in hotels should adapt to the changing temperatures throughout the seasons. Use Shelly Pro 3 to control the motorized valves in your water distribution box and manage heating, cooling, or other motorized valves in your building. 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.
LIGHT AUTOMATION FOR COMMON AREAS
Reduce unnecessary monthly costs with Shelly's smart lighting solutions. Shelly Pro 3 can control three separate light circuits and gives you full control over common areas like halls, garages, and storage rooms where the lights are usually on all the time. Now you can make them energy-efficient with the built-in scheduling and scripting features of Shelly Pro 3. To fully automate your spaces, 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.
