Weird. I have hello home actions that I’ve been using for months that do have a motion sensor trigger events of different device classes, but don’t change the mode. Maybe I had them set up to change the mode when I first started and then removed that event?
There are lots of reasons why you would want to do this without changing the mode.
For example, I have the deadbolt unlock and the light turn on when I’m letting the dog in from the yard. Can’t do it with shortcut groups, because the door and the light can’t go in the same group. But I’m not changing the mode. I was home, I am home, I’m just briefly opening the door to the backyard.
I tried to set a test phrase up by starting with the mode change, which did let me use “when things start to happen,” and then after it was saved unchecking the mode change. It did let me save that a second time. However, that hello home action is not triggering at all. And I’m afraid to change anything else in the configuration I have.
I’ll see if I can borrow another motion sensor from a friend of mine and see if I can get any new hello home action to work with the new motion sensor trigger. But that may take a couple of days.
