You can use a custom edge driver for it. You’re connecting it directly to a SmartThings/Aeotec hub, right? Not via a hue bridge?
If so, try this one:
[Edge Driver] Hue Motion Sensor (No Hue Bridge)
if it still shows up as a thing, you may have a model with a slightly different fingerprint. If so, ask for help in that thread and hopefully they’ll be able to get it added to the custom driver.
