How to reverse smartblind position scaling from 0-100% to 100-0%

Questions & Help
1

I have add Ikea Fyrtur blinds via Matter to Homey Pro and find that they are scaled so that 0%=Open and 100%=Closed.

My other blinds ae Z-Wave and scale the other way round, i.e. 0%=Closed and 100%=Open.

For consistent Alexa voice commands of position for all blinds, I want to reverse the scaling of the Fyrtur blinds, so they are same as my Z-Wave blinds

How can I achieve this?

If you want 40% open, you recalculate to (100-40)=60%
In general: if you want x% open, you recalculate (100-x)%, so when x=0 the result is 100 and when x=100 the result is 0.

Is there no “invert” option in the advanced settings of the device?

Hi David,
I am not very familiar with VIRTUAL DEVICES App, but I guess you can link a virtual device to one of your blinds and link the properties in a way that the recalculation is done automatically.
Probably also Device Capabilities, but I don’t know that at all.

Sadly no invert available

Thanks Dirk. I think that using a virtual blind , if that can be controlled by Alexa, might then be used to set the physical blind using the calculation suggested by Rmb and jhoney12.

I have started to experiment with the Logic Card for Calculate, but it’s use is new to me and there is much to learn.
