On start the tool asks, if you're at home or not. On basis of this input it de-/activates the connections as mentioned above. After that it waits until you get home or leave it and automatically changes the connection.

Before first start, you have to configure block 2 and block 22:

Block 2 - define the coordinates of your home.

Block 22 - define your Wi-Fi connection.

Have fun.
