On wiring-diagram.com, you have the option to share projects via link or QR code.
On one hand, this makes it easy to send via email; on the other, it gives you the option to stick a QR code into the distribution board as digital documentation.
This way, the code can be quickly scanned on-site with a phone to access the current status.
To make it really great, the protection device overview was still missing alongside the wiring diagram.
You’ll now see the following view when you open a wiring diagram via the QR code:

The cable names and device identifiers are always shown. Both can be changed if needed (in the wiring diagram edit mode); for this, look under the protection devices for the option “Manual assignment of device identifiers”.
If you still prefer to have a printout in the cabinet, you can of course still find the data as an Excel download under Exports -> Protection device overview.
Enjoy digitizing!
