Configuring covers with local-tuya

I have a few Tuya cover controllers controlling shutters.
LocalTuya recognizes the devices, but I’m having trouble setting them up.
The functionality I would like for each of the devices is as follows:

  1. a command to set the cover to a given percentage: 0-close, 100-open, and anything in between
  2. Manual commands: open, close, stop
  3. A timed command for closing. This is to make sure the shutter is fully closed (shutter motors can be inaccurate with their timing, so I want to give it a few extra seconds to make sure)

I am trying to add this functionality from the integrations UI, adding one entity at a time.
I find the options: ID, Open_Close_Command Set, Positioning mode, Current Position, Set Position, and Invert 0-100, confusing and somewhat redundant.

  1. Do I need to set an entity for each operation? up, down, close, timed_close, …?
  2. Would it be easier to somehow set it up in yaml? if so, how?
  3. How can I delete my current device and entities and start over?
