Get meter values for a specific transaction

GET 
/transactions/:id/meter-values

Retrieves granular telemetry data (meter values) recorded during a charging session, including power, current, voltage, and energy readings.

Use Cases:

  • Display charging curves and power graphs
  • Analyze charging behavior and efficiency
  • Export detailed telemetry for billing or analytics
  • Debug charging issues or power fluctuations

Performance Tips:

  • Use time filters to reduce payload size for long sessions
  • Request only needed measurands (don't fetch all types)
  • Higher limit (up to 1000) reduces number of API calls
  • Meter values are typically sampled every 30-60 seconds
info

Meter values are raw telemetry data sent by the charger. Sampling frequency depends on charger configuration (typically 30-60 seconds for periodic samples, or on significant value changes).

tip

For graphing power curves, filter by measurand=Power.Active.Import. For energy consumption over time, use measurand=Energy.Active.Import.Register.

note

Some chargers send multi-phase readings (L1, L2, L3). Check the phase field to differentiate between phases.
