Raspberry Pi shows up on an Ubiquiti network

[Velvis]

I noticed 2 Raspberry Pi's connected through WiFi on a clients network.
Any ideas what these would be in an office environment?

Could literally be anything. Plex servers, honeypots, POS terminals.

Hard to guess...asked the client?

I used to use them years ago for digital signage systems running YoDeck on it.
