@irqnet were you able to figure out why nothing happens if you connect to the coffee machine?
I had to change the serial port from /dev/ttyAMA0 to /dev/ttyS0 for my RPi3.
Now the coffee maker just replies with what I'm sending to it.
If I connect the coffee maker ground to the RPi ground I'm unable to read anything.
