# Live Data
At Service>Application>Live Data, you can view the latest data of devices in different plants. This function supports a device to refresh data every 10s. It should be noted that this function working normally requires two conditions:
- The device supports the function;
- The device is online.
When it works, you can view detailed data of the device by tapping it.

For devices that do not support the live data, it may be caused by the following reasons:
Pocket type supported, but firmware version not supported: Contact your distributor or installer to upgrade the firmware.
Pocket type not supported: Consult your distributor or installer about the proper dongle type to purchase one.
Micro inverter and Datahub do not support the function.
[!Note]When you have switched away from the dynamic energy flow diagram or closed the live data function for 15 minutes, the device data will stop reporting.
