EDIT: It’s DONE.
Sure! It’ll take some cleanup, and then some setup work to build (i use Sloeber, not the arduino IDE) but it’s definitely possible.
My code base has a few nice features as standard: HTTP server (for control and status info), Telnet server (for direct debug output), OTA update, and MQTT/Homie.
It does not have any kind of runtime configuration, though. Everything is hardcoded, even SSID. I will always be a programmer, so it’s not worth it for me to spend the time making anything runtime configurable – it’s actually easier for me to just re-compile and re-upload.
