The motion sensors don’t pair with the hub, but are designed to pair directly with the light bulbs and the outlet. So you could use them in that way to know when they have activated and thus control other things.
However, if these outlets work reliably as inexpensive Xiaomi repeaters, the Xiaomi Aqara motion sensors are much smaller, faster, nicer looking, cost less, measure ambient light in lux that reports back to the hub ( not the simplistic react/don’t react approach of the IKEA motion sensor), and Xiaomi do pair with Hubitat.
