I don't know if this is new or not. I don't' recall seeing it before today and only found it today because of an article I read about GH "Night Mode". It lowers the volume and lights at your prescribed time. You can also mute any notifications at the times you choose. In the GH app, choose the tv/speaker icon in the upper right corner. Find your device and tap on the 3 dots and then settings. Tap on Enable Night Mode and choose your desired settings. Nice feature...hint hint Alexa!
