Hi
I’ve made a blueprint to be able to set different volumes to my speakers depending if it’s day or night. It triggers on time than du choose and do not change volume of playing mediaplayers. This works good together with my other blueprint that change volume when mediaplayer goes inactive.
Try if U like
