Okay. Starting off the post to say that not all HomeKit apps are created equal. So far, I've noticed that the Home app is severely lacking I've had more precise capabilities with Eve and Hesperus. Hesperus has allowed me to create rules that include "when brightness is less than x%", which I haven't seen in Eve or Home yet, so I'm loving that. One thing I haven't figured out is to do with Motion Sensors. I can see how to turn a light on when motion is detected, that's easy. Does anyone know how to set up a HomeKit automation to switch off a light when motion hasn't been detected in the last 5 minutes?
