[RE-wrenches] TED MONITORING

[Glenn Burt]

As you know, the TED uses a Power Line Carrier communications scheme where
data is impressed on the 60Hz AC waveform for distribution throughout the
house. There are many pitfalls in this method of data comms, but it can be
done and be reliable.

 

That being said here is my experience with the TED - I have 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 communications within a half hour of the circuit being
turned off.

 

We have a solar customer that installed a 5000 on his house for an
inexpensive net meter monitor. I happened to visit him last week to install
an SMA Sunny Beam with BlueTooth on his inverters. He told me his experience
with the TED was very similar to mine, it would lose communications with the
display at unpredictable times.

 

So reliable? Not in my experience. Inexpensive? Yes.

 

YMMV

I was intrigued by a previous thread on Google Powermeter and the TED 5000
and tried to setup on two system.

 

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".

 

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.
