Please add a Player / Motion Sensor peripheral to the Mod to allow the computer to track nearby players and or Mobs.

Plethora's entity sensor should provide this functionality already! It's not something I currently want to replicate in CC:T as I'm not sure it thematically fits.

Works Plethora with the 1.14 ?

Not yet, no. It's in the pipeline, but also a rather big update and I'm somewhat limited in time & energy right now.
