I'm using Home Assistant for my home automation, it has some basic graphing capabilities but only for the last 24 hours. I'd like to create graphs both with fine granularity and over long periods of time.
I have a home office in the basement, where I smoke cigars. I have a large extraction fan with a pretty serious airflow that pulls the smoke out and keeps the room in negative pressure so the smoke and fumes doesn't reach any other parts of the house.
I am interested in seeing how the different fan speeds affects the temperature in other rooms in the basement, and how it again is affected by the outside temperature so e.g. summer vs winter.
For this I need to plot various temperature and other sensor data over long periods of time, and I need to be able to see how the different sensor readings correlate (or not).
What are some good graphing tools that are easy to interface with home automation and IoT sensors or the Home Assistant?
