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.
