+- `unique_serial` will use a uuid-based serial/model number instead of the default `BlindsHTTPAccessory`. This should only be required for specific external integrations (such as Eve) that may have problems with identical serial numbers for multiple devices.
+
 - `use_same_url_for_stop` will send the previously sent url (either, `up_url` or `down_url`) again. This is for specific blind types that don't use a standard stop URL.
 
 - `trigger_stop_at_boundaries` sends an additional stop command when moving the blinds to position 0 or 100.  Most blinds dont require this command and will stop by themselves.
