Has anyone connected a display to the Opta, maybe through the USB port or some mystery internal connector? I'd like to have a simple LCD, even just a few lines of text, mounted on a typical steel enclosure door with the Opta inside.

Hello!
You can connect RS485/ModBus compatible displays
Se cerchi bene nella porta aux trovi un'uscita i2c e una seriale oltre a GND, 3.3 V. e 5.0 V.
Quindi puoi provare a collegare dei display Nextion su seriale o semplici display i2c
