Sound volume manager app based on time of day

[mystvearn]

Hi,

I used to have the do not disturb function on my note 3 turned on. However I have to disable the feature as I missed few emergency calls after midnight. I now have two sound profiles I created with elixr app. The sound profiles are a widget on the home screen. Every night at around 930 I turn it on. The night profile has the volume about 20%. In the morning, I switch back to full volume profile.

Is there a way to automate this?
