Completely agree. There should be a Night/Sleeping Mode. This can be like an in between of Home and Away… the primary reason is you might want to have a kitchen sensor or back door not armed during home (say you have a dog, letting them out etc during the day), but it should be armed while you’re asleep.
But you’re right – why not just let users make as many mode configurations as they want? That solves a lot of problems with one single feature
