The total amount of money we spend, was around 800 Euro. And it needed a lot more effort and parts, than we had expected. We also needed to consider, that working with high voltage needs the hands of a specialist. Here we were very lucky to get the help of our friend Christian Ketzer, who is a master electrician and technician. Without his help, we could never have finished all this.

So what needed to be done?

First we had  to fork 380V, 32A from the distribution cabinet in our cellar. For that we

• build a socket for three 35A fuses into the cabinet
• connected a distribution panel with a 32A CEE socket

To get the current and the network out of the house we used

• A 6 meter, 6 square millimeter five-pin rotary current cable with CEE plug
• A hole through our cellar wall, with waterproof sealing
• A 7 meter CAT5 flat network cable

Outside we needed a stable mount for the wallbox. There for we needed

• 2 ground anchor
• A stainless steel post box mount

For the modification of the wallbox we then got

• A Raspberry Pi with case
• A 4,3 inch monitor (had to be converted from 12V to 5V)
• A 5V power adapter to put on the DIN rail in the wallbox
• A digital power meter

Last, but not least, a nice sign to our charging station

• One ground anchor
• 2 meter zinc-coated steel pipe
• 2 mounting rings
• A protecting cap
• The sign itself

And of course lots of time and patience :-)
