With the FRITZ!Box you can control devices like the DECT 200 (Power Switch) oder the DECT 301 (radiator valve). For this, the FRITZ!Box must be registered as a gateway.
If a login with username and/or password is configured on the FRITZ!Box, you have to configure it also within the Gateway configureation. If there is no username or passord you can leave the input fields blank.
You don’t have to register the devices controlled by the FRITZ!Box as a device. IRControl creates the device element itself during the initialisation process of the gateway.
Configure your FRITZ!Box with a Mac adress or IP. For more Information have a look at the chapter network configuration.
