Question about EB Troller Wallbox

The wallbox from EB Troller (type 2, 11 kW, 16 A, CEE 16) does not have an OCPP interface. No support for OCPP is mentioned in the available product information, only an app function for controlling and monitoring the charging process. Retrofitting with OCPP is generally not possible if the wallbox does not support this function from the outset.
