I'm trying to automate my dumb roomba. For this I ideally need a couple of buttons. I'm lost at how to add another button, that would have a different name and a different sent byte.
Additional question - to get info from the roomba (charging, battery, etc.) I need to send a similar byte series and then receive two unsigned bytes. I have no idea how to do that.
As for the other thing, that might be something you need to write your own driver for? if you need some inspiration, this repo has a driver for mitsubishi heatpumps, which does something similar (read/write to a uart): https://github.com/echavet/MitsubishiCN105ESPHome
