I really want to combine them with RAG, plus doing some agentic stuff on my home server which runs a number of services, some as Home Assistant. So I want it to read all the sensors every hour, and then message me if anything occurs out of the ordinary (with ordinary equaling the historical data provided by the RAG).

No idea if this will work or not, but it's how I learn to use new technologies.

You could of course build this using traditional software development.
