I have a pi zero functioning as a doorbell (with camera & opencv) One pi 3 running moonlight to stream my win10 desktop (with gaming!) over ethernet to my living room tv. One pi 3 running a display in the hallway. (purpose: grafana/ip cam views/etc) One pi 3 operating a cnc machine (octoprint etc).
