A Raspberry Pi4 with a generic 10” touch panel from Sunfounder can be made to do anything with basic Python programming and a Tkinter GUI. Any hardware IO device you could ever need can be bought from Sparkfun or Adafruit. Ethernet, serial, I2C, IR, take your pick. You really need to be into tinkering and coming up with your own equipment enclosures though. Not for the faint of heart, but the ultimate in customization, and my personal favorite DIY solution too. Probably just as reliable if not more so than anything else out there.
