I... guess, if you're only looking at the outcome (boxes of caught Pokemon) it is similar?

But the linked post describes a Raspberry Pi + Capture Card + OpenCV solution that is scanning the screen to detect when Shiny Pokemon are found, which is much more involved.

The $30 'Switch Up' device I linked to seems to operate only on emulating button inputs. Like, you can record and playback a macro.
