You could technically do this with Nextcloud, but that is definitely overkill just for a file drop.
The next best thing I can think of for this would be localsend with auto accept enabled.

PoE++ Type 4 goes up to 100w, its Type 3 that goes to 60w. Why the hell they didnt just call it PoE+++ I’ll never understand

Yeah, home assistant is tiny… I’m not sure what he expects? Does he need it to run on a pi zero or something? Lol

That is actually dependent on what you are doing. With gigabit ethernet being full duplex, you can transfer 1Gb/s both up and down at the same time.

This would mean that if he has a single port, if he was downloading a file from the internet, he could still reach 1Gb/s. If he, however, had 1Gb up and down, he could only download at 500Mb/s and upload at 500Mb/s simultaneously.

His upload being so much lower than his download would lead to him not likely noticing any difference.
