Good morning, gents. JDRoberts is correct.
To put it another way… there are really 2 main “states” that motion sensors have :
(1) BEING READY to receive any commands from the hub, and likewise transmit any messages to the hub.
(2) ACTIVELY SENSING and sending motion data to the hub (at its simplest, it’s simply “yes, I’m detecting motion”, in real time).
Right now it appears that both (1) and (2) are happening as far as SmartThings go. Motion-sensing events are being sent all the time and we decide whether or not to do something with it.
Since this product is called SmartThings, it implies that it is smart. Smart implies efficiency among other things. So, there should be no need to be in State # (2) if there’s no need for it, e.g. if the overall mode is Home.
The smart benefits and side-effects of this smart separation is, saving battery life, and also not doing PIR sensing, and not sending motion data, when none of these are needed because everyone is home.
I just got my reply from the sensor manufacturer, will post it in my next message.
