I may have made a mistake here…
I was referring to Ikea motion sensor
The 4th reply shows a DH but now that I had to look it up again it seems like that the one mentioned is actually for the Hue Motion Sensor.
My bad!!! So if I got this correct… The button on the back is still leading, even though i didn’t put luminance settings through the SmartThings settings, the physical switch on the device trumps it?
