Your meCoffee will need to be aware of the state of the brew button to make this happen.
Fetch the remaining black wire from the first cable set. It has a female connector on one side and a female+male connector at the other side.
Connect the female end of the wire to terminal #1 of your meCoffee.
Remove the existing orange wire from the upper right terminal of your brew button. This wire carries a live signal which opens the valve. Connect this wire to female+male side of the black wire.
Finally reconnect the combined wires to the upper right terminal.
Remove the existing red wire from the upper terminal of your brew button.This wire carries a live signal which drives your pump. Connect this wire to the female+male side of the black wire.
Finally reconnect the combined wires to the upper terminal.
Test for the definition of succes. If it fails, try to connect the black wire to the other terminal and retest. Markus : your cabling is colored differently : please let me know which one worked.
Now would be the time to relax a bit and leave the machine to warm up for about 20 to 30 minutes. Are you ready for your first meCoffee’d shot?
From now on all steps are basically optional: if you do not really need the timer, preinfusion or pressure: skip these steps. Installation can be resumed at any time.
Shot timer in meBarista appears as soon as you press the brew button
