Cannot register a FRITZ!DECT smart plug
Registration of the FRITZ!DECT smart plug, for example FRITZ!DECT 200, to the FRITZ!Box fails. After you push the DECT or Connect button on the FRITZ!Box, the DECT connection is not established. The smart plug is not displayed or is displayed with an inactive connection in the menu "Smart Home" in the FRITZ!Box.
Simply proceed as described below. After each measure, check whether the problem is solved.
1 Maximum number has been reached
A certain number of smart home devices can be registered with the FRITZ!Box. If you already registered the maximum number of devices, you cannot register any more, and therefore no smart plugs.
2 Unlocking the buttons
- Click "System" in the FRITZ!Box user interface.
- Click "Buttons and LEDs" in the "System" menu.
- Click on the "Keylock" tab.
- Disable the "Buttons locked" checkbox.
- Click "Apply" to save the settings.
3 Disabling "Reduce DECT field strength"
- Click "Telephony" in the FRITZ!Box user interface.
- Click "DECT" in the "Telephony" menu.
- Disable the option "Reduce DECT field strength" in the section "Radio Field Strength".
- Click "Apply" to save the settings.
4 Disabling "DECT Eco"
- Click "Telephony" in the FRITZ!Box user interface.
- Click "DECT" in the "Telephony" menu.
- Disable the option "DECT Eco" in the section "Radio Field Strength".
- Click "Apply" to save the settings.
5 Enabling encryption
- Click "Telephony" in the FRITZ!Box user interface.
- Click "DECT" in the "Telephony" menu.
- Enable the option "Permit only secure DECT connections (recommended)" in the section "Security".
- Click "Apply" to save the settings.
- If the option was disabled, you must then restart the FRITZ!Box once using the user interface ("System > Backup > Restart").
6 Setting a PIN
For automatic registration to work, you must set the PIN to "0000" in the FRITZ!Box user interface:
- Click "Telephony" in the FRITZ!Box user interface.
- Click "DECT" in the "Telephony" menu.
- Enter "0000" as the PIN in the section "Registration".
- Click "Apply" to save the settings.
7 Registering the FRITZ!DECT smart plug and deregistering it
You can restore factory settings to the FRITZ!DECT smart plug and deregister it. This deletes a faulty connection to the FRITZ!Box or the FRITZ!Smart Gateway and all of the settings that are preventing a connection from being established:
Loading the factory settings of the FRITZ!DECT smart plug
- Push and hold down the DECT button on the FRITZ!DECT smart plug three times in a row for at least 6 seconds each time.
Registering the FRITZ!DECT smart plug
- Click "Smart Home" in the FRITZ!Box user interface.
- Click "Devices and Groups" in the "Smart Home" menu.
- Click the "Delete Device" button.
- Click the (Delete) button next to the respective device.
- Click the "Finished" button.
