A single module that detects motion, transmits the X10 code to AM's, etc.  and which keeps batteries charged to maintain memory.

This product would solve several problems; distance, battery, memory, and it eliminates the receiver part of a transceiver.

I like it!   

Maybe a lithium ion battery inside, and a removable power plug...  Auto-sensing non-overcharging circuitry...

I guess it would cost a bit more, but certainly better than reprogramming those motion sensors and disposable batteries!

It's the sensor to transceiver distance problem that I first wanted to solve.

As for reprogramming, I have a simple solution that will work with all battery devices.

Solder a very short piece of wire (1/2") at the + and - of the battery string.

In the case of MS16a's that would be 3 VDC.

Every few months or so, bring new or recharged batteries plus an extra 2 batteries in a holder with 2 wires and alligator clips.

Clip on the external 3 VDC, change batteries, and nothing in memory will be lost.

Remove clips and on to the next device.
