Not quite automation in the traditional sense but I built a pseudo KVM which allows me to switch between my work and personal MBPs. With the press of a button it will switch my 32" 4K monitor's input to the 'other' device as well as my apple bluetooth keyboard and trackpad.

It connects to both laptops through bluetooth and has a LiPo battery making it completely wireless. I 3d printed an enclosure that lets me mount it out of sight underneath my desktop (think up-down controls for a standing desk).

This lets me easily switch between computers through the day without plugging in/re-pairing/etc.

It's still needs a bit of refinement but overall, it's quite nice and makes switching devices painless.
