here's a strange one (for me anyhow). I have the DS7000 security system, Active Home Pro and the W572rf32 (i think that's the number).
Seems like anytime there is an ATV close by or I am using my pressure washer, it is causing some of my lights to come on. I really don't have time to investigate. Just thought I'd throw this out to see if anyone else has experienced something similar. BTW, the pressure washer is gas powered and not electric.
Strange huh.
