Hello,
after the last update Home Assistant 0.105.2 the icons for the switch do not change color. They always remain the same color when the state changes.
Before the update, the problem did not occur.
according to the Blog post
" Icons no longer change color based on state
A change that is not really apparent at first, but you probably notice it sooner or later.
The entities card no longer changes the colors of icons based on states, except for lights.
…
So, that is why we disabled it, by default, for all entity types, except lights. However, we did add a new option: state_color . Using this option, you can decide if you want to old behavior back, add it to more entity types or maybe even disable it for lights too!"
