+## SwitchBot Blind Tilt
+
+The blind tilt is exposed as a cover entity with control of the tilt position only:
+
+| Tilt Position | Blind State |
+| ------------- | ----------- |
+| 100%          | Closed Up   |
+| 50%           | Fully Open  |
+| 0%            | Closed Down |
+
+The close button will close the blinds to the closest closed position (either 0% or 100%), and defaults to closing down if the blinds are fully open. Because Home Assistant believes 100% is open, the default cards will disable the open button when the tilt is at 100%, but the service call will still work and open the blind to 50%.
+
+### Simple cover template entity
+
+Some integrations may expose your SwitchBot Blind Tilt to other services which expect that 100% is open and 0% is fully closed. Using a [Cover Template](/integrations/cover.template), a proxy entity can be created which will be open at 100% and closed at 0%. This template entity is limited to closing in one direction.

 ## Error codes and troubleshooting
 
 The SwitchBot integration will automatically discover devices once the [Bluetooth](/integrations/bluetooth) integration is enabled and functional.
