Very nice! We’re about to hook up our coffee consumption to our service monitoring.

Could you give me more insights on the pinout of the coffee machine’s service plug, please? The picture is too dark to guess which cable goes where, it seems to look like they just moved GND from 5 to 1, but I want to be sure ;)

Also, since you don’t use the level shifter, what voltage does it use on the RX/TX lines?

Thank you!
