I think this is another case where different things work for different people. I have many of the same concerns about motion sensors controlling lights, but in our house we have it set up the other way – – motion turns the lights on, but we don’t have inactivity turn the lights off, since if I’ve fallen I don’t want to be lying there in the dark while I’m waiting for assistance.
@rayzurbock wrote one of the first smartapps to deal with bathroom lighting, in his case he specifically tried to allow for someone being in the shower by capturing humidity trends. There was a lot of good discussion in that thread about different use cases and it was interesting to see how different people often wanted opposite sets of rules. This was all before Core was available. Choice is good.
