Before firing up your meCoffee we need meBarista up and running and your boiler shut down so you can work on a cool machine.
Run the app and browse around. Now find the Bluetooth-settings panel of your device and check if Bluetooth has been enabled. If not, do so.
Now remove the gray live-wire from the brew-thermostat.
This prevents the machine from heating up during the first steps. Make sure the disconnected wire does not touch any conductive surface.
The brew button still works
You have a working copy of meBarista and Bluetooth is enabled
