Google Home sends invalid MoveToLevel Command without mandatory TransitionTime #179
Description
When using Google Home App on iOS, if I try to dim the light it says "Something went wrong" and jumps back to 100%.
I have this plugin enabled for Alexa, and Google. Alexa can dim the light without issues.
