Is that A10 or A11 ?

If you are like me, you have probably started out slowly with X-10 automation.  You might have added one or two devices to "play" with.  It is a pretty safe bet that one of your earlier devices had A1 as its address.  When you got  the next device, you changed to the next highest number.

 

Now, with 6 or more devices, it can get confusing which address controls what.  The first time I set up a MS13A motion sensor, I didn't pay attention to the "dusk and dawn" feature.  Besides detecting motion, the MS13A can also trigger lights to come on at dusk and off at dawn.  The address used is 1 higher than the base  address of the sensor.  For example, if the sensor is set for A3, then the dawn/dusk feature will use address A4.  All of a sudden, you may have a light turning on and off for no apparent reason.

 

So am thinking about my addressing scheme.  I plan on adding a number of SR227 modules and I have to think about how to add them into the mix.  Should I group addresses by room?   Maybe by function ?  I guess I will have to think on this for awhile.  What do you think?  Do you have a plan that you follow ?
