I just installed my smartwings shades this week, and have the same issue. 'Open shade' from Alexa issues the 'setPosition' command with a value of 100, which is invalid. Smartwings apparently only accepts values from 0-99 as valid. 'Set blinds to 99%' works fine from Alexa, but not exactly wife friendly... Is there a community z-wave driver that we can use, or is there a way to get the official driver to limit values to the accepted range?
I also attempted setting up a rule for this, but could not get it to trigger, since the command is rejected before processing (thus no position change) and there is no event that I can trigger on.
