I tried to find the thread, but the search capability of the
discussion list search engine is a bit limited ...

I found a number of "pet immune" motion sensors, such as this:

GE Wireless - Pet Immune Motion Sensor
(www.home-technology-store.com/home-security/GE-60-807-95R.aspx)

Would these work with the WR800? Kind of pricey at $84.95, but for
main human presence detection may be worth it.
