Configuring AVM FRITZ!Box Smart Home Control
The Sunny Home Manager communicates with FRITZ!DECT products such as radio-controlled sockets or thermostats only indirectly via the FRITZ!Box.
Requirements:
You must have a FRITZ!Box with Smart Home software support.
The FRITZ!Box must be equipped with the DECT function.
The FRITZ!DECT products connected to the FRITZ!Box must have been correctly connected and commissioned (see manufacturer's manual).
The radio-controlled sockets connected to the FRITZ!Box must be able to measure the energy consumption.
You must be logged in to your FRITZ!Box with a user name and password. You should have this data ready, as the settings for the FRITZ!Box login must be the same in the home network and in the Sunny Home Manager.
Procedure:
- In the menu Configuration, click on Device overview.
- Click on Properties in the row of the Sunny Home Manager.
- Click on [Edit].
- Go to AVM FRITZ!Box Smart Home control and click on Yes under FRITZ!Box Smart Home available:.
- Further setting options open up.
- Under FRITZ!Box login to the home network: keep the FRITZ!Box user and password default setting.
- Under FRITZ!Box address: keep the default setting fritz.box, enter the IP address of the FRITZ!Box, or the IP address under which the user interface of your FRITZ!Box in your home network can be reached.
- Under FRITZ!Box user: enter the user name you entered to log in to your FRITZ!Box.
- Under FRITZ!Box password: enter the same password that you used to log in to your FRITZ!Box and repeat this under Repeat:.
- Click on [Save].

From the version FRITZ!OS 7.25 and the change in the system security of the AVM Fritz!Box, it is no longer possible to log in with a password only.
A virtual user is automatically created in the FRITZ!Box with the name "fritzxxxx" (x = number between 0 and 9). This means that the connection data that allows the Sunny Home Manager to switch radio-controlled sockets on the Fritz!Box needs to be adapted accordingly in Sunny Portal.
Therefore, SMA recommends selecting FRITZ!Box-Benutzer und -Kennwort (FRITZ!Box user and password) when logging into the home network and has defined this option as the default.
The setting "FRITZ!Box-Kennwort" (FRITZ!Box password) can now only be used for older systems.
- After a few minutes, the FRITZ!DECT products appear in the Overview of new devices and can now be configured.

If you have a FRITZ!DECT radio-controlled socket or a FRITZ!DECT thermostat, the ambient temperature of the device is displayed on menu page Smart Home > Temperature.
