Stupid question about hooking up a streamer

Hello, all. I've been thinking of stepping up from my Bluesound Node, and have been looking at Innuos products, specifically a Zen Mini. My question: The Bluesound, of course, is wireless, but the Innuos is not. We've got an Eero mesh wifi system that has worked well throughout the house. Could I simply add an additional unit onto the Eero system, located near to the equipment rack, and run an ethernet cable from the new box to the Innuos, or does it actually need to be hard-wired?

As things stand, the router is a very long way from the stereo. Though I can imagine running a very long ethernet cable from the router to the stereo -- through the floor and into the basement, etc., etc., etc. -- I'd much prefer not to.

For what it's worth, the wireless signal is very stable. My wife has been on Zoom meetings for work while I've been streaming tunes upstairs without a glitch for either one of us. (Not sure if this info matters, but I figured it wouldn't hurt to know.)

Thanks very much for any help you can give an old boy on this score.
