It’s just that the rules operate alot simpler than folks think. It’s pretty much “when this happens” (purple circled action), “then this happens” (red circle/red dots, one action at a time, down the list if more than one). There is a smidge more logic if you have a trigger or scheduled rule when you have the “time” variable (green circle) where the rule then only triggers if you are within the time frame added.
Now looking at what you want to achieve above, here are atleast two ways you can accomplish that with an away shortcut and a home shortcut.:
Use the shortcut to turn the cameras on or off. I have included a screen shot above of the “away” button, just think that the “home” would be the exact opposite. When the cameras are on, make sure to enable motion detection and notifications in settings. That way when ever the camera is on, it’s detecting and notifying you of events in app and showing events clips in the event tab.
This shorty only turns on motion detection when away, and the home would disable motion detection. In you camera settings, enable notifications, but they will only be sent to you when motion events are created when detection is enabled via the shorty.
I like this way, because it leaves the camera “on” at all times, because I have each of my cameras set to record to my local sd card (most are continuous recording, and some are local event only). If I were to turn the camera off, local recording would not be possible.
