Default Wireless Motion Sensor Battery Life?
I'm looking to add several wireless motion sensors to my HA setup, but I am hoping that someone can give me some real-world experience as to the quality and battery life. I certainly don't want to be changing the batteries every couple of months.

X10 has a very cheap module: X10 MS16a - I'm naturally very suspicious that I'd get a lot of false triggers when the heat comes on or the wind blows.

Optrex has quite a few versions: Optex - for the price these better not false trigger but they claim they won't.

I do have 2 cats so I don't want them to trigger the sensors.

BTW: is this newsgroup archived somewhere or do all the posts drop into the ether over time?

Thanks in advance...
Eric

Or someone breaths. Anywhere. Ever.

I had a house alarm that the prev tenant left. It used a couple
batteries that lasted for YEARS. Mostly I setup at the alarm base
to "see" someone in the living room and turn on lights.

That may be an issue. Dogs (and bunnies) tend to stay low to the
ground. A large warm cat 5' in front of the sensor isn't much different
than a person 15' away.

Have you looked? Where?
netnews never dies. I've found posts of mine from 1986.
