Well, I've made some headway.
The only way I could find to get Luma onto my Pi entirely successfully was to git clone it. I then discovered that it selects the wrong device type even if I select the correct device type unless I remove every other entry from the device import list rather than just selecting the one I need from the list.
This is the only working code I have so far...
It can't make head nor tail of any of the documentation I've found for Luma and am a total noob when it comes to Python, so I have no idea how to select a different font or set the font size. Neither can I import time (just hours and minutes would be fine) and store it in a variable in a way that displays in this mode.
For the font, I'm getting a screen full of warnings...
...when following the suggestion here...
https://github.com/rm-hull/luma.oled/issues/247
...that's flagged as a closed issue.
Please tell me it's actually all very simple and I'm just being an idiot.
