**To retrieve an asset property's historical values**

The following ``get-asset-property-value-history`` example retrieves a wind turbine asset's total power values for a 20 minute period in time. ::

    aws iotsitewise get-asset-property-value-history \
        --asset-id a1b2c3d4-5678-90ab-cdef-33333EXAMPLE \
        --property-id a1b2c3d4-5678-90ab-cdef-66666EXAMPLE \
        --start-date 1580851800 \
        --end-date 1580853000

Output::
