@paco Hmm.
I don't think esphome can do USB HID (yet?) without some custom C++, so you'd need to figure out an alternative.
For the remote LEDs and buttons, LEDs don't really care what voltage you drive them at but I don't know how much current the ESP32 pins can realistically sink. Probably you'd looking at some sort of 5V tolerant GPIO expander to drive them and the buttons.

@paco something like this (not a recommendation, just an example): https://www.amazon.com/AITIAO-Expander-Extension-2-5-5-5V-Communication/dp/B0B82L2ZCQ/ You'd run 5V into VCC of that, SDA/SCL would come off the ESP32, and the grounds would get tied together. Then they just show up as more GPIOs in esphome: https://esphome.io/components/pcf8574/
