the previous generation (1000) in my house and have had it for a few years now.
It works well about 80% of the time. It seems to lose communications with the transducer
in the AC load center when a few different circuits in my house are active –
a 3 bulb under cabinet light in the kitchen for example. It does seem to regain

<p class=MsoNormal>I was intrigued by a previous thread on Google Powermeter
and the TED 5000 and tried to setup on two system.<o:p></o:p></p>

<p class=MsoNormal><span class=apple-style-span>In both cases, they did not
work.  I know they were installed correctly and factory support has me
moving wires, getting noise filters, using different branch circuits, etc. In
other word they make it my problem. Their out is "you have too much
noise".<o:p></o:p></span></p>

<p class=MsoNormal>Who else has given the TED a try and what are your results?
At this point no comment on Google Power meter since I have not gotten to that
point in the setup yet.  My suspicion is the TED is not up to speed design
wise. <o:p></o:p></p>
