I couldn’t find any rules for this community and I don’t know if it’s allowed.

Its allowed up to the limits of the lemmy.world TOS, so no direct links, discussion is fine.

mainly because everyone says it’s the best thing to use a homelab for.

Great for self-hosting if its something you use. Not really a homelab thing, these two things are not necessarily the same either. My hosted services for the family are entirely segregated from my lab, which does a very different job.

How much is it utilized (in watch hours/week for example, mine was less than 2/week)?

Over the past 30 days.... Up to 6 streams at a time, 15 days worth of streaming hours.
