To display the measured values and the join date, call up the device list. The list shows when the last measured value was received.
Select the device for which you want to display further information.
Select the Readings tab. The join date is displayed in the field on the right. It is important to note that the join date does not show the first connection attempt, but rather when the last connection was established. If the connection was unstable in the meantime and the device rejoined, it is possible that there were already measured values even though the join date is further in the future.
