7. Advanced Techniques > 84. Check for Dead Motion Detector Batteries

Check for Dead Motion Detector Batteries

Instead of scurrying about the house checking the batteries in your various motion detectors, have a script do the checking for you.

The X10 motion detectors [Hack #6] draw so little power that their batteries can last for months at a time, even when the detector is in a high-traffic area and is activated frequently. However, as the batteries weaken, the detector’s transmission range drops off and its signal might not be reaching your transceivers. Also, if you have a lot of detectors, it’s more convenient to get notified when the batteries need changing instead of having to periodically test and confirm that each one is still working—provided that you can remember where they all are in the first place.
