Ouranos is the companion application of Gaia. It can be used to manage multiple instances of Gaia, log data and it provides a web api to retrieve data.
Ouranos is still in development and might not work properly.
Ouranos is written in Python (v. >= 3.9) and requires some extra dependencies, some that might not be shipped with Python.
Make sure you have them before trying to install Ouranos.
To do so on a Raspberry Pi, use
apt update; apt install python3 python3-pip python3-venv git rustc (or
sudo apt update; sudo apt install python3 python3-pip python3-venv git rustc
if required).
To install Ouranos, copy the install.sh script from the scripts directory and
run it in the directory in which you want to install Ouranos
