I was able to help flipmoo with his blinds. He wanted to tap-and-hold and then release the button when the blinds reaches the desired position.

> Wellicht kan het met een transition uit de chronograph app: (Ik heb geen zonnescherm dus ik dim als voorbeeld mijn keukenlamp. Ik heb ook maar één knop die vasthouden en loslaten ondersteunt. Waar ik ‘Dim niveau ‘ gebruik, moet jij de positie van het zonnescherm gebruiken) Stel het zonnescherm gaat in 25 seconden van 0 (%) naar 1(100%), dan duurt het vanaf 0,35 (35%) open naar 1 (100% ) dus (1-0,35)\*25 seconden. Er zijn dan ipv 100 stappen (1-0,35)\*…

(I don’t have a sunshade so I dim my kitchen lamp as an example. I also only have one button that supports holding and letting go. Where I use ‘Dim level’, you have to use the position of the sunshade)

Suppose the sunshade goes from 0 (%) to 1(100%) in 25 seconds, then it takes from 0.35 (35%) open to 1 (100% ) so (1-0.35)\*25 seconds. Instead of 100 steps (1-0.35)\*100 steps are needed. I put these values in variable ‘runtime’ and ‘steps’

Each time the transition reaches a step, the transition value is therefore 0.01 higher and the sunshade is opened 1% further.
