About AquaPi
Why Choose AquaPi?
-
AquaPi is an open-source project designed to connect your aquarium to your home automation system.
It uses an ESP32 microcontroller and various sensors to monitor your aquarium's water quality and other parameters.
AquaPi then sends this data to your home automation system, like Home Assistant, allowing you to view it, set alarms, and create automations.
-
AquaPi can monitor several parameters, including:
Water level
Water leak
Temperature
pH
Salinity
ORP
Dissolved Oxygen
CO2 - Gaseous
O2 - Gaseous
Humidity
and more!
-
Yes, AquaPi is designed to be flexible, allowing you to add your own sensors and create a custom solution for your aquarium.
-
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.

AquaPi Builds
Choose an AquaPi build that best suits your needs.
This is the base model, providing core monitoring capabilities with a Raspberry Pi 5 flashed with Home Assistant.
Includes Kasa Power Strip and sensors for essential parameters like temperature, water leak detection, water level, and pH.
It also allows for additional add-ons, such as ORP, salinity and dissolved oxygen sensors, for more specific configurations.
Total Peace of Mind for the Modern Aquarist. The AquaPi Essentials kit is our most popular configuration, providing a robust, all-in-one solution for monitoring the health and safety of your aquarium. By combining critical water parameter tracking with active leak detection, Essentials ensures that you are always in control of your slice of the ocean (or jungle).
The "Big Four" of Aquarium Safety:
The Essentials kit includes everything in our Basic version, plus the high-precision tools needed for daily stability:
Laboratory-Grade pH Monitoring: Includes the world-class Atlas Scientific EZO™ pH circuit and a lab-grade probe. Experience stable, accurate pH tracking that integrates directly into your Home Assistant dashboard—no more squinting at color cards.
Active Water Leak Detection: Guard your floors and your sanity. The included leak sensor triggers instant smartphone notifications or can even be programmed to shut off your return pumps the moment moisture is detected where it shouldn't be.
Dual Optical Water Level Sensing: Two food-grade infrared sensors provide the ultimate redundancy for Auto Top-Off (ATO) systems or high-water alerts.
High-Accuracy Temperature: A waterproof DS18B20 thermistor provides real-time data, allowing you to create "Smart Heater" fail-safes within Home Assistant.
What's Included:
Home Assistant: Raspberry Pi 5 with 4GB RAM and 32GB SD card, pre-installed.
Included Sensors: Temperature, Water Level, Water Leak, pH (Lab Grade), Kasa Power Strip (6 Outlets).
Additional Sensors: Salinity, ORP, Dissolved Oxygen, Peristaltic Pumps, Gaseous CO2, Gaseous O2, SnapCam and more! Available separately on our store.
