Updating firmware

When updating the firmware, you have the option of importing the firmware to the wallbox. The wallbox software is updated to the latest version.

The firmware can be updated in two ways:

Via the KOSTAL Smart Energy Meter from wallbox FW version 2021.50.9128-202.
This update can be carried out by the user.
Directly via the wallbox.
The update may only be installed by an electrician.
