불꺼 스마트 홈 IoT is a utility app designed for Android that facilitates efficient control of home lighting and electrical devices using advanced RF400Mhz communication technology. This app allows users to manage their smart devices from both inside and outside the home without requiring any personal information or subscription fees. Its robust communication range makes it suitable for larger spaces, accommodating up to 200 meters without obstacles and 100 pyeong (approximately 3300 square feet) indoors with obstructions.

The app supports various 불꺼 switches which can control lighting and power for electrical appliances. Users can easily turn devices on or off individually or in groups, set timers for automatic operation, and create customized modes for different scenarios such as reading or watching TV. Additionally, the app can automatically turn off all devices when the user leaves home, making it a convenient solution for modern smart home management.
