Did you ever figure this out? The extra parameter seems to have broken my Alexa integration as it no longer responds to open or percentage, only on or off.
Hi, thanks julienhd.
Partly it works for me, partly it does not.
An example of what I see in the state (http://homeassistant.local:8123/developer-tools/state) of a roller shutter (cover.sunricher_hk_zcc_a_16e193fe_window_covering
) which cannot be tilted and therefore the tilt control is not desired:
I rewrote the supported_features value from 255 to 15, clicked on “set state”. This induced temporary absence of the tilt control slider. However, after a while (10 seconds?) or maybe after I did the same procedure for other roller shutters or if I changed the shutter position by the up/down arrows, the tilt control slider was back there and so was the value of 255 in the configuration.
Similarly, when I try to change the cover class (from blind to shutter or shade) in the configuration (experimenting what may lead to solution), it induces the change temporarily (change of icon in the overview) but then it reverts itself to blind.
Any idea please of what step or procedure I am missing?
