Anything in the open source realm with a similar use case of watching for something specific to change on a web site?

Would be nice to run this from a home server/raspberry pi.

I don't know about OSS server side software, but I use the free version of Distill on my own computer in the browser, so it's run locally. My browser is always open, so it's a good platform for checking changes.

Change Detection on F-Droid is pretty great, not sure if you wanted it on a PC or not.
