### Full configuration using advanced templating
|
||||
|
||||
The `position_template` can accept JSON, where `position` and `tilt_position` is provided at the same time.
|
||||
|
||||
The example below shows a full example of how to set up a venetian blind which has a combined position and tilt topic. The blind in the example has moveable slats which tilt with a position change. In the example, it takes the blind 6% of the movement for a full rotation of the slats.
|
||||
|
||||
Following variable might be used in `position_template`, `set_position_template`, `tilt_command_template` and `tilt_status_template`, `json_attributes_template` (only `entity_id`).
