It's possible to deactivate a charging station. Go to the "Chargers" section to get an overview. There, you will see three dots on the right side of the screen. Click on the dots to deactivate your charging station. Deactivated chargers can be found again by selecting "advanced search" and then checking "inactive only". Please note that you can only deactivate a charger if it is not linked to a location. In that case, you must first disconnect the charger from the relevant location before you can remove it.
To reactivate the charger follow the same proces on an inactive charger.
