(feat) Allow slider inversion via yaml config

[bjornsnoen]

Useful at least for tradfri covers. They report 0% when fully extended
and 100% when fully withdrawn. Makes sense from a closed/open perspective,
but not so much when represented as a slider.

Please add this to the base branch.

See #75 and #64.

If implemented, I think it would be neater to have it happen if step: is set to a negative value.

If implemented, I think it would be neater to have it happen if step: is set to a negative value.

I would disagree, that would introduce secondary functionality to the step function and would potentially affect other parts of the sytem, rather than being just a change in the presentation layer.

[thomasloven]

Yes. You are right.
I'm still considering this. The close before was accidental.

[MADS0LADEN]

Any news on this? :)

[dagope]

why is this solution not accepted?
if conflicts are resolved this feature is very useful.

Would also like to see this implemented. The Somfy Covers reported via HomeKit are open with 100% and closed with 0%. The idea of creating my own cover template is nice, but for 20 covers this would be an enormous effort. Especially if the original somfy app is showing the percentages inverted already ;)

Thanks

Had to bump rollup-plugin-typescript2 to ^0.31.0 to build with node 17 locally, didn't commit it as it's not relevant to the PR but probably had an impact on the build artifact?

Hi @thomasloven,

First of all, thank you very much for this great card!

Re he inverted feature: are you still reluctant adding this?
The PR raised by @bjornsnoen works perfectly and superhandy opposed to the cover template solution you proposing.

@bjornsnoen many thanks for your efforts and solution. This is a key feature for me.
