Endless use applications

Common area temperature control

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.

Lights automation of the common spaces

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.

Pro Series features

HTTP/HTTPS webhooks for quick connection

Enhanced with HTTP/HTTPs webhooks, Shelly Pro line can easily connect with, notify or control other compatible equipment or 3rd party automation system.

Smart actions that follow the Sunrise/Sunset

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.

Automation with weekly scheduling 

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.

Scripting for custom automation

Shelly Pro line fully supports mjS scripting, allowing customers to create their own features and functionalities.

Enhanced safety features

Overheating protection

In case of unsafe temperature levels or rapid temperature increase, device switches off the outputs and sends notification. Internal temperature sensor is measuring the heat every 100 ms.

Overpower protection

Detected overpower will lead to outputs switch off by the device and it will immediately send a notification. Overpower protection feature protects the device and other electrical equipment from potential damage.

*Feature is available only for power metering-enabled devices

Overvoltage protection

Voltage peaks could be dangerous for electrical appliances and machines. To avoid damage to the electrical appliances the device switches off the outputs when overvoltage peaks are detected and immediately sends a notification. 

*Feature is available only for power metering-enabled devices

Flame Retardant (V-0)

All Shelly Pro components are produced with flame-resistant materials and will keep their construction even when exposed to high levels of heat.
