Incomplete OCPP Implementations
No EVSE vendor fully implements the entire OCPP feature set. OCPP is a vast protocol with multiple versions, each with core and optional feature sets.

Diverse OCPP Interpretations
OCPP standards are interpreted variably by different vendors, affecting implementation consistency across models and firmware updates.

Firmware Update Challenges
Vendors frequently update firmware to add features and fix bugs, but there’s no guarantee that your application will remain compatible with every firmware version.
