Mount them upside down and lower. There is a section in the user guide that came with the HMS that discusses this.
Found online:
Wyze Motion Sensor v2
The motion sensor lets you know when large movement is detected. Where these come in handy: the garage, your nursery, or a back porch.
Tip: Mount your motion sensor on a wall ~7 feet high with the Wyze logo pointing to the LEFT . Do not place it near heat sources, or behind large objects.
Tip for pet owners: Standard mounting may result in false positives if you have large pet. Instead, mount your motion sensor on a wall or corner ~3 feet high (or just above your pet’s height). Make sure the Wyze logo is pointing to the RIGHT .
