Put the output from any script or program into your macOS Menu Bar (the BitBar reboot)
My macOS laptop always had a four-letter braille string corresponding to the current IPv4 address on the tray, using xbar  (formerly BitBar). I'm aware of approximate shapes for frequent addresses so I could quickly recognize them.
The main problem with this approach is that, you can only quickly recognize strings that you already know and you can't quickly decode arbitrary strings. In particular braille glyphs are too similar to each other, like ⢁ and ⠡ which are almost identical. In fact the actual tactile braille has the same issue and can often be decoded only with the context. Something like 1892 braille  might be better for encoding arbitrary sequences.
