Endless use applications

Control lights on 2 phases

Automate the lights and optimize their energy consumption through smart schedules, timers, and extended scripting functionalities. Shelly Pro 2 allows you to control the lights on 2 phases and control them separately by setting custom schedules and smart timers. Set the lights on the operational floors to switch off completely after the working day is over and switch back on only where it is necessary at 7.00 in the morning. This way, you will not have to worry about any forgotten lights or efficiency.

Automate your valves 

Use Shelly Pro 2 to control the motorized valves in your water distribution box and control heating, cooling, or any other motorized valve in your facility. This way, you can protect your premises from flooding and make your spending more efficient by using the Shelly device's built-in scheduling and scripting functionalities. Smart schedules combined with temperature & humidity sensors and precise weather data will provide dynamic control of the heating system for an optimal indoor climate.

Sockets automation for efficient energy usage

Make sure that no energy goes to waste by automating the sockets' power supply with Shelly Pro 2 and use the smart scheduling function to cut off the power to all heavy consuming electrical appliances between 7:00 PM and 7:00 AM during the weekdays and over the weekend. That way, you will cut the energy consumption of these devices in half, which will result in significant optimization of the monthly energy cost. 


Working on 2.4 GHz Wi-Fi network, supporting Access Point (AP) and Client Mode (CM) options

Add devices fast and easy via Bluetooth connection, using the Shelly Cloud App

LAN connection for high security and reliability. Simultaneous Wi-Fi and LAN usage, as backup, when needed.

Grouping Scenes

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.
