Remote diagnostics

Remote diagnostics lets an operator inspect charger status, faults and diagnostic information through a management system without first visiting the site. It can help support teams decide whether a problem can be resolved remotely or needs an engineer. OCPP supports remote monitoring and device-management functions, with later protocol versions providing a richer device model for charger components and variables. Diagnostic logs can also be collected as part of charger support. Remote diagnostics is useful only when the data is trustworthy. Incomplete telemetry or inconsistent firmware versions can make a remote fault look different from the condition at the charger.
