Assuming the [`recorder`](/integrations/recorder/) integration is running, historical sensor data is read from the database on startup and is available immediately after a restart of the platform. If the [`recorder`](/integrations/recorder/) integration is *not* running, it can take some time for the sensor to start reporting data because some characteristics calculations require more than one source sensor value.
