Why is my motion sensor showing up as a Responder in a scene?

[Oakland Jeff]

I have a scene for a three-way switch with switches at either end of a hall, and a motion sensor on one end of it. Both switches in the scene are controllers and responders for obvious reasons... either switch can turn on the light and both switches must reflect the current status. The motion sensor is in reality a controller only, but when I click on it in the device tree outside of the scene, the little membership tree on the far right tells me it's both a controller AND a responder to the scene. Why? And what is the best way to make it just a controller only? I'm on 5.3.

Thanks,
Jeff

With ISY, "controllers" are, by default, also "responders".  I guess this is a residual from that definition, even though it make little sense for a motion sensor to be a scene responder.  I do not believe there is a way to define something as only a controller.  I also believe it does not matter here...motion sensors do not listen and are unaffected by controller action.  I would ignore this.

OK, cool, motion detectors don't listen or respond. But then just to be super clear, there is no need and no benefit to setting all my Motion Detectors to "Ignore" in scenes? I was thinking that doing so might somehow reduce traffic or something.

To be honest, I am unsure about this.  I doubt that it would hurt, but I suspect that it would not change anything in the context of a motion sensor.
