 At the moment, platform cover support the opening and closing of a cover. You can control your covers either using coils or holding registers.
 
-Cover that uses the `coil` attribute is not able to determine intermediary states such as opening and closing. Coil stores only two states — "0" means cover closed, and "1" implies cover open. To allow detecting intermediary states, there is an optional `status_register` attribute. It will enable you to write your command (e.g., to open a cover) into a coil, and read current cover status back through the register. Additionally, you can specify values for `state_open`, `state_opening`, `state_closed`, and `state_closing` attributes. These will be matched with the value read from the `status_register`.

-If your cover uses holding register to send commands (defined by the `register` attribute), it can also read the intermediary states. To adjust which value represents what state, you can fine-tune the optional state attributes, like `state_open`. These optional state values are also used for specifying values written into the register. If you specify an optional status_register attribute, cover states will be read from status_register instead of the register used for sending commands.
