I have develop a custom integration for the Witty One EV charging station from Hager.
The connection is made by Bluetooth BLE
Sensors include
- Total energy
- Energy per phase
- Current charging session energy
- Current charging session time
- Power
Install
Add the custom integration
Before adding the device in the configuration put the charging station in pairing mode with the card of the station (led blue alternating)

It is my first integration and it’s still limited. If someone wants to read and comment my code he is welcome.
I need to find other BLE characteristic to have the connection status with the car.
I do not know how this integration will handle one phase installation.
If you know what are the important data for a charging station to put in home assistant you are welcome.
