The charging points that work offline are only connected to the car. As soon as the plug is connected, the charging point starts charging and it stops as soon as the plug is disconnected or the battery is full.
Most modern charging points are equipped with the latest technologies and are connected to the internet. They can be easily integrated into the home network via WiFi. This way you always have insight into the charging history and electricity costs and you can read the charging station via the app anywhere with an internet connection.
