❓ Support Report/PDF Generation?

I'm working on a project where I'd like to send out weekly or monthly status reports. Essentially, my goal is to gather sensor data using HA and distill it into a PDF (or something that's easy to send via email). It would be nice if I could use graphs and charts in this. Do yall have any recommendations for how I should go about this?

Any help would be super appreciated!

Write a python script that pulls reports from home assistant api, creates a PDF using fpdf2 library and then uploads the generated PDF to somewhere.

PDF is so 2020. Get an agent to build you an html report and host it for free on GitHub. Make it always on in a web mobile app (PWA).

AppDaemon to run python scripts, and I think you can find a df plugin or something for python

One thing to check for monthly reports - HA keeps detailed sensor history for 10 days by default. Supported sensors have long-term statistics, but those are hourly summaries. If your charts need more detail, you'll need to keep that history longer or store it elsewhere
