Setting up the switch on sound function for FRITZ! smart plug

You can configure the smart plug, for example FRITZ!Smart Energy 200, so that it automatically switches when it detects certain sounds. It switches when it detects clapping, knocking, or a different sound you specify.
For example, you can configure it so that the light in your garage turns on automatically when steps or voices can be heard and then turns off again after 10 minutes.
