AquaPi Essentials: The Complete Safety & Stability Suite

Sale Price: $739.00 Original Price: $760.00

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.

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

Guides on Setup, quick and easy once Home Assistant is established!
Please visit our
GitHub Page for much more information on this product!

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

Included Sensors:

  • Temperature Probe - DS18B20 Waterproof Thermistor. Can add up to 2 with a Y-cable with additional programming

  • Optical Sensors w/Mount - 2 Food Grade Optical Infrared Water Liquid Sensors with Magnetic Mount

  • Water Leak Sensor - Liquid Detection Sensor, 6ft Cable, 2 Mounting Screws w/Magnetic Mount (NOT RECOMMENDED FOR USE WITH SALTWATER)
