The chargepoint identity is the name of the charger with which it connects to a backoffice. Basically, it's the charger saying "Hey, this is me!" to our platform.
As such, you must know the chargepoint identity in order to find it.
A Chargepoint Identity is also sometimes called:
Chargepoint ID
OCPP ID
CSMS ID
Charger Number
How to find the chargepoint identity?
It's usually just the serial number of your charger.
Volt Time chargers identities are "VT_[serial number]". So if the serial number is 0001234, the identity is "VT_0001234".
If you want to be sure, check the documentation of your charger or ask the seller.
