Set maximum cover position to individual percentage

Hi there!

I have a rather specific question: I would like to control my roller blinds (Aqara Roller Shade Driver) via Apple Homekit, Home Assistant or directly at the roller blind control by pressing the buttons as follows:

1. open button: open roller blind to a specified height (“e.g. 80% or 100%???”).
2. close button: close blind completely (“e.g. 0%”)

These are the known standard operations. In addition, I would like to set a third position which opens the blinds more than 100%, e.g. for cleaning the upper part of the window, which is normally covered by the roller blind for aesthetic reasons.

3rd position (e.g. triggered by a Home Assistant scene): Roller blind opens further with the corresponding trigger than is possible with the standard buttons (“e.g. 100% or 120%???”).

What would be the smartest way to set this up?

Kind regards and many thanks in advance for your help!

I’m looking for a similar thing. I’d like to adjust the percentage values, as currently HA “71 %” equals to 1/2 open/closed. I’d prefer to set “50 %” for that. The scaling is a bit wrong… not aware of an idea on how to adjust that :frowning:
