Returns interval time series telemetry for a single asset over a requested time range. Each interval can include active power in kW, reactive power in kvar, voltage, current, power factor, total harmonic distortion, frequency, and state of charge. Use the optional metrics filter to return only the series you need; metrics that do not apply to the asset type or have no reading for an interval are returned as null. Use this endpoint for the asset Insight view, performance review, and charting.
