Key information includes the `timerMode` (ON/OFF) and `timerTimeout`, indicating when the mode will switch OFF. A GET request retrieves the current fan state. The `SetTimer` command, using a POST request, adjusts the `timerMode` and `duration` (optional, default 900s) within a range from 1s to 43200s. A potential `FAILED_PRECONDITION` error arises if the device lacks fan capability.\n"]]
