Behaviour of FRITZ! radiator control in case of power or internet outage

If you are using smart home devices, for example FRITZ!Smart Energy 200, FRITZ!Smart Thermo 302, or the LED light FRITZ!DECT 500, you can specify how the smart home device is switched after a restart, for example after an update or a power outage.

Note:All instructions on configuration and settings given in this guide refer to the latest FRITZ!OS for the FRITZ!Box.

1 Behaviour of the smart home device during an interruption

If the FRITZ!Box loses power, if there is no internet connection, or if the DECT connection is interrupted, the settings of the radiator control, for example FRITZ!Smart Thermo 302, remain intact, but automatic switching of the devices is limited. For example, routines can no longer be triggered and access via FRITZ!App Smart Home is not possible.

A properly functioning FRITZ!Box with an internet connection and an existing connection to the radiator control are required for smooth and correct operation.

2 Specifying the switching state of the smart home device after an interruption

You can specify the switching state for smart home devices after a FRITZ!Box restart, for example after a power outage or installing an update:

  1. Click on 'Smart Home' in the FRITZ!Box user interface.
  2. Click on 'Devices and Groups' in the 'Smart Home' menu.
  3. Click on the (Edit) button for the respective smart home device.
  4. If you selected an LED light, click on the 'Light Setting' tab.
  5. Enable the desired option under 'Switching state'.
  6. Click on 'Apply' to save the settings.
