Hello, I wanted to share the web app I've been working on for anyone who is interested. It's open source, feel free to modify it or contribute your ideas if you want, the only catch is you can't profit from it, it's for you are your reef buddy's.
The app is built for a Raspberry Pi, it runs on a Pi Zero 2 W, Pi 3 and Pi 4. Currently it's not compatible with the Pi 5 as that requires the latest Bookworm OS and sadly Raspberry Pi made a lot of changes to that. It will load but you can't switch anything on/off as the way it interacts with the GPIO's have changed. At some point I will be digging into this so it works but for now you'll have to use the Legacy Bullseye 32-bit version of the operating system. You can use the Raspberry Pi Imager program to install the OS.
www.raspberrypi.com
Here's an install script to install it.
NOTE: The Raspberry Pi username needs to be the default “pi”
Stable Version 6.6
Beta Version 6.7
This will start the installation, follow the on screen instructions.
After installing it you can go to "Settings" and then "Configure Ports" screen, at the top you'll see an "Custom" option, select that and you can configure the Pi GPIO's. By default a PCA9685 is enabled so you'll see pins for it, if you don't use you can ignore it.
The app is built on Apache server using MySQL database. The backend is a C++ program running on 4 threads with PHP and the frontend is JavaScript. You can access the database by running phpMyAdmin.
Add /phpmyadmin/ to your Pi IP address like the example below.
