AquaPi for ESPHome is a project that helps you build a powerful aquarium monitoring and automation system using affordable ESPHome devices and Home Assistant. Make endless automations and monitor temperature, water level, and upgrade for advanced aquarium monitoring: pH, salinity, dissolved oxygen, and more (using EZO circuits and probes).
Why use AquaPi?
- Open-source: Freely available for anyone to access, modify, and contribute to.
- Modular: Designed to be easily expanded and customized based on your specific needs.
- Modernized: Utilizes the latest technologies and tools for a seamless user experience.
- Customizable: Adapt the system to fit your unique aquarium setup and monitoring preferences.
- Versatile: Expand the system’s capabilities with your own compatible sensors and equipment.
- Affordable: Offers a cost-effective alternative to many high-end monitoring solutions.
- Powerful: Provides comprehensive monitoring capabilities for various water parameters.
