<p>Sends a list of asset property values to IoT SiteWise. Each value is a timestamp-quality-value (TQV) data point. For more information, see <a href="https://docs.aws.amazon.com/iot-sitewise/latest/userguide/ingest-api.html">Ingesting data using the API</a> in the <i>IoT SiteWise User Guide</i>.</p> <p>To identify an asset property, you must specify one of the following:</p> <ul> <li> <p>The <code>assetId</code> and <code>propertyId</code> of an asset property.</p> </li> <li> <p>A <code>propertyAlias</code>, which is a data stream alias (for example, <code>/company/windfarm/3/turbine/7/temperature</code>). To define an asset property's alias, see <a href="https://docs.aws.amazon.com/iot-sitewise/latest/APIReference/API_UpdateAssetProperty.html">UpdateAssetProperty</a>.</p> </li> </ul> <important> <p>With respect to Unix epoch time, IoT SiteWise accepts only TQVs that have a timestamp of no more than 7 days in the past and no more than 10 minutes in the future. IoT SiteWise rejects timestamps outside of the inclusive range of [-7 days, +10 minutes] and returns a <code>TimestampOutOfRangeException</code> error.</p> <p>For each asset property, IoT SiteWise overwrites TQVs with duplicate timestamps unless the newer TQV has a different quality. For example, if you store a TQV <code>{T1, GOOD, V1}</code>, then storing <code>{T1, GOOD, V2}</code> replaces the existing TQV.</p> </important> <p>IoT SiteWise authorizes access to each <code>BatchPutAssetPropertyValue</code> entry individually.
