 ## Conclusion
 
-This application note shows how to implement an effective home automation system that can control roller window shades with Opta™️. By leveraging the internal RTC of the Opta™️ and NTP server time data, the proposed system can accurately and automatically control the shades based on pre-programmed scenarios. Additionally, the proposed system can be easily monitored and controlled through the Arduino IoT Cloud, providing users with remote management capabilities.
