What is AquaPi for ESPHome?
AquaPi for ESPHome is an open-source project that allows you to connect your aquarium to your home automation system. It uses an ESP32 microcontroller and a variety of sensors to monitor your aquarium's water quality and parameters. AquaPi then sends this data to your home automation system, Home Assistant*, where you can view it, set alarms, and create automations. Learn More

Please note:
AquaPi is a handcrafted product: Each unit is individually made, and as such, comes with no warranty.
Functionality and quality are rigorously tested: Every AquaPi undergoes thorough testing to ensure it functions properly and meets quality standards.
Not intended for all users: While functional, AquaPi might not be suitable for everyone seeking a fully polished consumer product.
Limited support: We offer assistance with troubleshooting basic sensor issues, but cannot provide comprehensive support for Home Assistant or ESPHome configuration.
Built on the foundation of Home Assistant and ESPHome, AquaPi empowers you to:
Monitor key water parameters like temperature, pH, conductivity, and more.
Receive real-time notifications of any critical changes in your aquarium environment.
Automate tasks such as lighting control, temperature regulation, and water flow adjustment.
Build upon the existing platform to create a truly personalized monitoring system

Open-Source vs. Proprietary: AquaPi is an open-source project. This means that the design and software are freely available, allowing for community contributions and modifications. In contrast, the Apex Neptune is a proprietary system with closed software.
DIY and Customization: AquaPi is designed for DIY enthusiasts. It uses a modular design with expansion slots, allowing users to add their own sensors and create custom solutions. Apex Neptune, while highly capable, is a more pre-built system with less emphasis on user customization at the component level.
ESPHome and Home Assistant Integration: AquaPi is specifically designed to work with ESPHome and Home Assistant. This gives users the flexibility and power of a general-purpose home automation system for their aquarium. Apex Neptune has its own software and ecosystem.
Cost-Effectiveness: AquaPi is designed to be an affordable aquarium monitoring and automation solution. By leveraging open-source software and readily available components, it can be a more cost-effective option compared to high-end commercial systems like the Apex Neptune.
Focus: AquaPi is primarily focused on monitoring and automation using sensors and integration with home automation systems. While it can control some devices, its strength lies in its data collection, alerting, and automation capabilities within the Home Assistant ecosystem. Systems like the Apex Neptune often include a broader range of built-in control features.
In essence, AquaPi prioritizes flexibility, customization, affordability, and integration with open-source home automation platforms, while systems like the Apex Neptune provide a more comprehensive, pre-built, and supported commercial solution.

Home Assistant is an open source home automation that puts local control and privacy first. This is what communicates and displays all your data from AquaPi, and so much more! This is what makes AquaPi different from other controllers. This can integrate with hundreds of other types of equipment and display the data in any way your needs require. While Home Assistant offers integration benefits, it is not a strict requirement for operating AquaPi. If you possess an existing Home Assistant infrastructure, AquaPi can function independently through its integrated web server.
Please note that functionality will be significantly reduced without Home Assistant. You only need 1 Home Assistant Instance to connect to multiple AquaPis. (see documentation).
-
Yes, AquaPi is designed to be flexible, allowing you to add your own sensors and create a custom solution for your aquarium.
