This product is ALL HYPE

[suckered]

Great advertising.  Lousy product.  Purchased AHP and a couple of WS12A dimmer switches, a couple of lamp modules, and an RF style (3 unit) switch.  I would say the AHP module stuck to the programmed schedule the first couple days.  After that, lights may or may not go on.  Or, go on at non-scheduled times.  The RF switch will only work if it's 10 feet from the control module (what range!).  The WS12A dimmer switch started going on whenever it wanted, even after I disconnected the control module and even with no bothersome appliances going (e.g. washer, dryer).  I finally decided to re-install my original (basic) switch, and in removing the WS12A I discovered that it was almost too hot to touch!  Needless to say I was glad I was removing this thing before something really serious happened.  What a waste of money!

    I am with you pal. I purchased over $400.00 worth and its a crap shoot on what will and what will not work.

While AHP & X10 have some challenges, a WS12A switch under normal use should never be that hot. You may of had a defective switch.
BTW... What where you switching with it? (It's recommended for incandescent lights only 60-300 watts.)

X-10 came onto the scene ~30 years ago. Unfortunately, in the years since then, *MANY* new (and unexpected!) electronic devices came onto the market that INTERFERE with X-10. 

Sadly, X-10 doesn't make this "critical information" public in their ads.

CLICK on my SIG LINK and spend some time reading - you'll learn how to get it all working...

Just my front porch lights.  All incandescent and well below 300 watts.

Interesting.....since the WS12A uses a neutral, it usually works better than the WS467.

Taketheactive is absolutely right. Since X10 hit the streets 30 years ago, a lot of things have come along (mainly switching power supplies) that throw monkey wrenches in the works.

It is not "a crap shoot"  but it is not "Plug -N-Play" either. You have to work at it a little, especially if you jump in in a big way.

You describe classic symptoms of noise and coupling problems. They are solveable, but at some additional cost and effort.

Check out "taketheactive" link, or search "noise" , "coupling" "filters" "repeaters" etc in this forum.

I've seen conflicting specs for the WS12A. I read one place that it was rated for use between 60 to 300W. Most specs I'm finding now say it is rated for 500W.

Wall switches will get warm and this is normal. A metal wall switch cover will act as a heat sink to dissapate some of the heat.
