well, from what I read there, EL34 had multiple repeaters.
JeffVolp said that is asking for trouble.....A1 ping pong.
You said you'd seen smarthome and another model do similar things.
Don't want to sound arrgumentative here, just digging for some answers.
hpdrifter,
The XPCR unit looks suspiciously similar to my Leviton HCA02 repeater (same case, innards??).
My Leviton unit does have problems with bright/dim commands. My solution - I don't use them.
My Leviton switches, and
most of the X10 dimmers made since '07, are capable of communicating with extended code
direct dim commands (these are referred to as
soft start units. This bypasses the "documented" problem with the standard bright/dim command sequence. My Leviton unit (and I believe the XPCR) do repeat these extended code commands.
Curious whether you have units that are extended code capable? Try re-identifying them as LM14a 2-way lamp modules within AHP. Move the module slider to 50% - if your unit responds, you are communicating with extended code.
If your units are not the newer "soft start" version, you'll have to deal with the old bright/dim sequence. I can't say for sure that you'll have a problem. On occasions, when I have tried this I've entered a loop with the CM15a sending and the HCA02 repeating for several minutes. Doesn't occur very often, but when it does it effectively locks up your HA system.
Both the ACT and JeffVolps repeaters are superior to the XPCR (I believe Jeff's is the Cadillac). However, as Dave W indicated, for $12 you can hardly go wrong with the XPCR. If you get the unit, you'll learn a lot about your system. Anytime you can learn you should leap at the chance.
