Un able to activate two of my ws12a in active home pro

[_tazz1969]

The problem is that some of m'y ws12a works fine.
I remark that i was unable to control additionnal module since i have installed à ws14a in a three way setup.

any idea?

Maybe a power line signal problem.
Do you have a phase coupler between the homes split phase incoming lines?
Have you done any X10 power line signal troubleshooting?
Is your setup using the CM15A or the CM15K {CM19A with a TM751}?
Is the CM15A or TM751 depending on AHP kit you have. Connected to the same circuit as the computer or UPS?
If your WS12As are older ones that are not soft start {ramp On and Off} Make sure you used the Older Lamp Before Soft Start choice in AHP. When you added them to AHP.

Thank you Brian
My Setup is only a CM15A.
I have correctly installed 2 WS12A switch that are working fine.
I have installed 1 WS12a with a companion switch (WS14A) and cannot control it, and no order device after that.
No split, standard home setup.
The switches by temselves work properly, but in AHP doesn't work.
I HAve installed an other WS12A on anaother swtich and samething.

If the problem switches are on the other phase of the homes wiring. They may not be receiving the X10 power line commands from the CM15A.
If you have not read the troubleshooting links yet. They may give you added information on how to find power line signal problems.
I didn't see in your list of devices. Any X10 filters or phase couplers.

Your description definately sounds like a phase coupling problem as Brian suggests. Are you in the US or North American on a split phase system? (Two 120V AC lines and a neutral coming in to home)?

My personal experience with WS12's and WS467 is they work best (as far as remote control) when the switch's black wire is connected to the "hot" feed line and the blue wire is connected to the load line. (The switch will always work locally, at paddle, or button, regardless of the black/blue wiring)

Read the troubleshooting links from Brians post, there will be a test later.

Thank you to both of you, i'll read that and make some change to view if it's working.
I'll post when resolved (hope so).
