# Selecting Devices
## Displaying Devices
After selecting **Devices** from the navigation menu, the following screen will appear.
You then choose a **Customer Group** and **Device Type**. All devices with the selected device type will be displayed in a list view.\
\
You can search for a specific device using the search function. You can search by Name, DevEUI/IMEI/DvnUUID or Customer name. First, select Name, DevEUI/IMEI/DvnUUID or Customer name from the dropdown menu, then enter your search term in the adjacent input field.
**Note:** Both the customer groups and device types you are authorized to select are added by a KPN administrator. If the relevant group or device type is not listed, please contact your KPN representative.
The following information is shown for each device found: the device’s UUID, the device type, the customer using the device, the current firmware version, the target firmware version (visible after new firmware has been prepared).
## **Selecting Devices for Update**
Once the list of devices is displayed, you can select the devices that should be updated.\
You may choose to update a single device, a selection of devices, or all devices by checking the boxes next to the devices you wish to update.
After selecting the appropriate devices, click the **Add firmware to devices** button. You will then be taken to the next screen where you can select the corresponding firmware and proceed with the [update](https://docs.kpnthings.com/kpn-things/kpn-firmware-over-the-air/devices/firmware-updaten).
