Manhot BL82-TYZ1 curtain state does not match position in home assistant, no option to invert_cover

What happened?

The state of the curtain (open, close, stop) is 0 = open, 100 = closed, while home assistant recognises the position as the opposite.

This leads to a very frustrating interaction in home assistant, where the open and close buttons get disabled when the curtain is closed and open respectively:

so you can only press "open" when the curtain is already open, producing no movement at all.

This seems to be a disagreement between vendor and HA, not a bug, but it leads to people needing to create additional templates just to control their curtains, and is very unnecessary.

There are a lot of posts about this issue, with some people suggesting setting "invert_cover" to true, but this specific converter (if i understand z2m correctly) does not have that option exposed. Manually setting it in yaml lead to the motor being bricked untill i disassembled it and pulled the battery.

What did you expect to happen?

I need the ability to configure the motor to home assistant standards - with 0% being closed - making the controls work as intended.

How to reproduce it (minimal and precise)

• Add the Manhot BL82-TYZ1 curtain to home assistant;
• Try to use the provided controls.

Start by locating the TypeScript converter for the Manhot BL82-TYZ1 device definition and inspect how its curtain state and position are mapped. Check how the converter exposes cover options, then verify that inversion can be configured safely and that Home Assistant controls report 0% closed and 100% open without reproducing the motor-bricking behavior.
