Endless use applications
Reduce unnecessary monthly costs with Shelly smart lighting solutions. Shelly Pro 3 can control three separate light circuits and give you full control over common spaces such as halls, garages, and storage rooms, which usually have their lights constantly switched on. Now you can make them energy efficient using Shelly Pro 3's built-in scheduling and scripting functionalities. To fully automate your premises, add Shelly Motion2 to switch on the lights automatically when someone enters, and its pre-set smart timer will switch the lights off once the premises are empty.
In guest rooms, reception areas, restaurants, or meeting rooms, keeping the temperature at a comfortable level is a key contributor to the comfort of both guests and employees. However, it is hard to maintain an optimal temperature without any energy going to waste. The cooling/heating systems in the hotels should follow the dynamic changes in the temperatures during the different seasons. Use Shelly Pro 3 to control the motorized valves in your water distribution box and control heating, cooling, or any other motorized valve in your facility. Smart schedules combined with temperature & humidity sensors and precise weather data will provide dynamic control of the heating system for an optimal indoor climate.
Enhanced with HTTP/HTTPs webhooks, Shelly Pro line can easily connect with, notify or control other compatible equipment or 3rd party automation system.
Shelly Pro line can switch on/off the power, depending on the Sunset/Sunrise hour, allowing dynamic control of the electrical equipment depending on the season.
Shelly Pro line allows you to set up to 20 actions based on your daily or weekly schedule with no need for an external hub or server.
Shelly Pro line fully supports mjS scripting, allowing customers to create their own features and functionalities.
