The option in automation to let the light flashing, short or long does work anymore.
I use Philips hue color lights and it did work but after last update it does not flash any more it only goes on.
Update
The light flashing problem is not completly solved in version 2021.12.2
It is blinking but there is no difference between long or short ({“flash”:“short”}).
After the blinking it stays on and does not return to the starting state (on or off)
I don’t think so because it happened right after the first December update (2021.12.1)
And it’s not only the flash, also all brightness options are gone.
If it is hue then ther is probaly a new hue library in the december release.
And if I take a look with the develop tool options i see:
min_mireds: 153
max_mireds: 500
supported_color_modes:
color_temp
xy
mode: normal
dynamics: none
friendly_name: Computerlamp
supported_features: 40
So I think they maybe still there (supported_features: 40) but not visible under same name.
