Unique in India

OCPP Log Inspector

See every OCPP message exchanged with your chargers. Raw JSON, timestamps, and complete message trails — the transparency operators need but rarely get.

The Problem

Most charging platforms hide OCPP details, treating the protocol as an internal implementation detail. When issues occur — failed sessions, stuck connectors, authorization errors — operators are left guessing. Vendor disputes become "he said, she said" without evidence. Debugging takes days instead of minutes.

OCPP Compliance Verification

Problem

New charger model needs certification before deployment

Solution
