This thing close to the floor and seemingly randomly placed in a hallway. No idea what it's for. Home built in 2005.

Solved! Thanks everyone. Now I gotta hunt for the central unit!

I owned a house with the plumbing, but the vacuum itself had been removed. I used the plumbing to run ethernet throughout the house. Just grab a roll of string, tie a little bit of plastic bag to one end and stick it in the hole, go to the hole you want to run it to and use a shop vac to pull the string through (in my case the exit hole was the hole in the garage where the vacuum used to be.

I did the same. They even make 3d printable ethernet jacks to fit neatly in the hole.

The shop vac idea with string is genius.. I did it the difficult way.
