I have both an indoor and outdoor hue motion and they both paired and are working great with my C8 Pro. I do have a lot of mains powered Zigbee switches so know the mesh is strong.
Regarding Aeotec multisensors, I used to have 2 v6 in use and removed both. They are extremely chatty devices with constant updates on the Zwave mesh. One went bonkers and started causing issues with my Zwave mesh. I won’t be buying any new ones but YMMV
