Welcome to the fastai community! It’s great to have you here.
To get started, I recommend learning a few terminal commands like sensors for Linux. You can find a helpful guide on how to use lm-sensors here and a video tutorial here. If you are on macOS, check out powermetrics via this blog post. For a more visual approach, the Python package Glances is fantastic.
I suggest finding a way to gather results from these tools and then using systemd (systemctl) scripts to trigger actions. This covers the data collection phase, which you can store on your disk. From there, you can learn how to write tests that detect specific thresholds and execute a response.
It’s often a good idea to map out the problem using Polya’s method, and just get started, as explained in this video. I also suggest joining the Discord for faster replies: fast.ai and trying advent of code from time to time.
Your project is more like automating the control of your computer, it’s definitely worth doing, but not necessarily related with AI. Do the fastai course and you will be a good AI practitioner that can complete real AI projects!
