...(I'm old and slow - the best of both worlds).
Welcome to the club! The "
Old Geezer's" can always use another TECHIE member!
...I'm not sure about the RR501 not stepping on the powerline communication (again some help here oldtimers) but I'll stand by the statement that 2 transceivers is risky unless used carefully...
The part "...2 transceivers is risky unless..." needs to be qualified - more than 1 'late model' RR501, set to DIFFERENT HouseCodes, will work fine. I had 4 running simultaneously with my CM11A and kept them when I began testing the CM15A (still testing...
). Only the 'late model' RR501s have "Collision Detection" circuitry (SEARCH the Newsgroup) - the 'early models' (the ones that only transceived what the slide switch was set to), the Stanley, the RCA - even though they "look" the same, don't have the additional circuitry.
And the TM751 - I haven't a CLUE why X10 marketed that except for COST!
I started out with the 'early model' RR501s and Stanley. Then, during the "Firecracker Introduction" got several friends and co-workers to buy the $6 PACKAGE - I thought I was in heaven... (until)
It all depends on how well you plan your '
RF Traffic Patterns' (
HOUSECODES: By Room or By Module Type or By Function or...?). I've even be able to add *ONE* TM751 back (controlled by an Appliance Module) for "
Nighttime Motion" ("
Nighttime Only" Motion Detectors control 'certain' lights in a path between the bedroom and the bathroom (and the kitchen - in case you're thirsty, or need to take some meds, too!).
