Neat! Can't tell if it has a speaker at the back or not. Would like to play sounds or alarms... I'd love to attach this to a PoE to USB-C ethernet adapter to talk to it over API via hardwired. Still looking for something like that. The flipper busy bar seems to at least have some connectivity over USB.

It has a small piezo buzzer, and you can use it to play RTTTL sounds. https://blueforcer.github.io/awtrix3/#/sounds https://blueforcer.github.io/awtrix3/#/sounds I have to warn that it sounds like hot garbage though. The neat thing with ESP32 devices is that you can make it sound okay using its built in 8-bit DACs, or great using I²S. Speaking of hardware hacking; you can also get POE/LAN adaptors for the ESP32, if you have free hardware pins left for it.

  +1 for the hot garbage piezo, but as OP says the ESP32 has a lot of fun hacking potential and there's plenty of space in the case especially if you remove the battery.
