Just got my TED yesterday and I have to say I am not happy.
I called before I purchased and they told me there were no issues that they know of with X-10.
Got the unit, installed it, and the sender works a total of about 2 feet to the outlet next to the breaker panel. EVERY other outlet in the house gets little if any signal.
The Leviton coupler repeater seems to completely screw up everything.
Calling TED back, they told me to REMOVE ANY DIMMER SWITCHES I HAD
They told me to REMOVE MY COUPLER.
This is total BS.
They finally after 4 phone calls agreed to send me a replacement transmitter.
If that doesn't work with a coupler in line the whole load of crap is going back to TED.
Oh.. load profiling does not work as advertized.
