## New device - Register weather station

You can now add physical devices, e.g. our weather station, to the created application. To do this, click on the + Register end device button in the middle of the window.

In the following window, we select to enter the end device manually:

The manufacturer has already stored a JoinEUI with additional IDs in the module. With a simple AT command (see LoRa-E5 AT command specification), we can read them out of the module and change them if necessary!

LoRaWAN_IDs_auslesen.zip

With the JoinEUI read out, then entered and activated, the DevEUI read out at the same time is entered directly afterwards.

After entering the DevEUI, an AppKey is generated. This key, generated in the TTN, is later entered in the Raspberry Pi Pico (H) program and is used to authenticate that the weather station is allowed to send data to the TTN.

It is therefore important to copy or make a note of the AppKey!!!

After entering an End Device ID, the device / weather station can be registered in the TTN.
