SUPLA is an open-source home automation app that turns inexpensive microcontrollers and small computers into a local control hub for lighting, gates, shutters and other devices. It gives a straightforward interface for operating Raspberry Pi, ESP8266/ESP32 and Arduino-based control modules, monitoring sensors such as temperature and humidity, and tracking utility consumption. Users who prefer a DIY approach and want privacy and flexibility will find SUPLA useful for toggling relays, dimming lights, running RGB scenes, monitoring sensors and viewing historical charts of energy, gas and water usage from a single app.
Key Features
⭐ Control modules for Raspberry Pi, ESP8266/ESP32 and Arduino work with SUPLA to build custom automation setups.
⭐ Open and close gates, garage doors, doors and gateways plus operate roller shutters from the interface.
⭐ Monitor liquid, distance and depth sensors and present temperature and humidity readings from connected sensors.
⭐ Manage lighting including RGB control, brightness levels and support for Varilight V-Pro dimmers.
⭐ Track electricity, gas and water consumption and generate charts for historical analysis.
Advantages
✅ SUPLA is open, free and based on open hardware and software principles, which reduces vendor lock-in.
✅ Local control keeps sensitive data on your network and improves responsiveness compared with cloud-only solutions.
✅ Broad hardware support lets hobbyists and professionals adapt modules to many use cases, from simple relays to sensor arrays.
✅ Unified monitoring and charting make it easier to analyze environmental data and resource consumption over time.
Disadvantages
❎ Requires compatible control modules and basic hardware such as Raspberry Pi or ESP devices, so it is not plug-and-play for all users.
❎ Initial setup, wiring and configuration demand technical skills and time to assemble a reliable system.
Development Team
The project behind SUPLA is community-oriented and built on open software and open hardware principles, with contributions from developers and makers focused on creating flexible, low-cost automation tools for DIY smart home setups.
