Pull request overview

This PR adds documentation for the FRITZ!Smarthome routines feature, which allows users to activate or deactivate self-defined routines from their FRITZ!Box smart home configuration within Home Assistant.

Key Changes

• Added a new "Routines" subsection under the "Devices" section
• Documents that routines are integrated as switch entities that can be controlled from Home Assistant
• Includes a reference link to the official FRITZ!Box knowledge base for creating routines

The line exceeds the 80-character limit and is not written in flowing text style. According to the documentation standards, there is no limit for line length, and content should be written in a flowing text style without hard line breaks. This sentence should be reformatted to remove the artificial line break at 80 characters.

[Copilot]

Several grammar and style issues need to be addressed: (1) "Self defined" should be hyphenated as "Self-defined" when used as a compound adjective before a noun. (2) The comma before "will be integrated" creates a comma splice and should be removed. (3) The phrase "and those can be activated or deactivated" is awkward—consider using "that can be activated or deactivated" instead. The corrected sentence should read: "Self-defined routines within the FRITZ!Box smart home configuration menu will be integrated as switch entities that can be activated or deactivated from Home Assistant."
