994 +== 9.2 Why node join succeeds but detailed data cannot be observed in the live data interface? ==
995 +
996 +
997 +The live data interface on the TTN platform is more orientated towards real-time observations, so if you don't click on the observations in time, you will not be able to see the previous details if you click on the interface again after a period of time.
998 +
999 +TTN has no fixed official explanation for how long this data refreshes, but actual tests show it to be around 10 minutes.
1000 +
1001 +
1002 +Users can see the time of the last activity of a node inside one of the Applications：
1003 +
1004 +[[image:image-20240820171935-1.png||height="714" width="1358"]]
1005 +
1006 +For example:
1007 +
1008 +* After 6 minutes of the last activity, click on the **live data** interface to observe the data.
1009 +
1010 +[[image:image-20240820172327-2.png||height="439" width="1365"]]
1011 +
1012 +* The last activity of a node that has not been clicked for a long time was more than ten minutes ago, and you cannot observe the previous detailed data by clicking on the live data interface at this time.
1013 +
1014 +[[image:image-20240820172513-3.png]]
1015 +
1016 +In addition, if one stays in the LIVE DATA screen for a node, several previous details have been observed. If the node is inactive for a long time to come, and the interface is refreshed at this point, the details of the previously active data may be refreshed and no longer displayed.
1017 +
1018 +
1019 +If the user needs to view the data uplinked from a previous node, the data can be retrieved through the endpoint given by **Storage Integration**. The data can then be distinguished between different nodes based on **device_id**.
