SUPLA is an open-source home automation platform that turns small controllers into a centralized smart-home system, letting you remotely operate gates, garage doors, shutters, lighting and other devices from your phone. The app provides a simple interface to control relays and dimmers, manage RGB lighting, toggle heaters and monitor a wide range of sensors including temperature, humidity, liquid and distance measurements. Users who build DIY installations or integrate off-the-shelf modules will appreciate SUPLA for its flexibility, energy and consumption tracking and the ability to generate charts that help visualize sensor and utility data over time.
Key Features
Remote control for gates, garage doors and access points with on/off actions and status monitoring, support for relays and dimmers, and RGB lighting management. Compatibility with Raspberry Pi, ESP8266/ESP32 and Arduino-based modules lets you build custom automation hardware within the same ecosystem. Sensor monitoring covers temperature, humidity, liquid level, distance and depth measurements, and the app can generate charts to visualize environmental and utility data over time. Energy, gas and water consumption tracking is available where supported by connected hardware.
Advantages
Because SUPLA is open, simple and free, it is accessible to hobbyists and small installations without licensing costs. Broad hardware compatibility allows you to select controllers and sensors that match your project and budget. The app provides monitoring and charting tools that help you analyze conditions and usage trends, and flexible control options cover common automation needs from shutters and gates to lighting and heaters.
Disadvantages
The system requires a level of DIY skill and basic electronics knowledge to assemble and configure hardware modules. SUPLA is not a plug-and-play commercial system, so initial setup and customization are necessary for full functionality. Feature availability depends on the specific hardware modules and firmware you choose to integrate.
Development Team
The project is community-driven and follows open software and open hardware principles, with contributors creating control modules and firmware for platforms like Raspberry Pi, ESP8266/ESP32 and Arduino to expand functionality and device support.
