Feature Request: the blinds need to close down
### Problem

The homebridge switchbot plugin only allows the blind tilt to close up. Would like to close it down. Using switchbot mini hub.

### Solution

There should be an option to either close up or down as per the user requirement.  The switchbot app allows the user to close up or down easily. Same functionality is needed thru this plugin.
