Use Cases

An awning that follows the weather

An awning that follows the weather

The outdoor motorized awnings offer pleasant shade for the establishment's visitors on sunny days. However, a strong, unexcepted wind can damage them beyond repair. By combining it with a wind sensor or simply by using a script to receive data for the weather forecast, Shelly Pro 2PM can automatically close the outside awnings to protect them from the wind. Additionally, if the weather forecast predicts rain in the afternoon hours, Shelly will open the awnings again to protect the outside seated customers.
Automated blinds for privacy control

Automated blinds for privacy control

Motorized blinds and curtains will not only encourage the use of more natural light but will also allow the guests of your hotel establishment control of their privacy by controlling motorized blinds or curtains individually. They can open or close the blinds or set the angle of the blinds according to their own needs and preferences.
Remote control of the parking gates

Remote control of the parking gates

Security services are costly to maintain. Shelly allows the automation of access control for your office or home, giving you remote control over your parking barrier or gate door. Use smart scheduling to set Shelly Pro 2PM to keep the barrier open between 6:00 PM and 7:00 PM when people are leaving the office to ease the traffic.
