I suggest reading through some of this thread as well as this post: Why can't you train Sense?. There’s a lot of detail here about why what you describe is not a feasible option.
Have you only had Sense for a week? That’s quite a short period of time for Sense to learn about your home. Machine learning requires a lot of data and Sense can only get that by seeing repeated on/off cycles of devices in your home. A few cycles just won’t cut it.
