Default Got a TED 1001 w/foot prints



Got a TED 1001 w/foot prints as an early X-mas gift..

It's been pretty frustrating, getting it installed..

In the outlets where the display (RDU) works, the updates are intermittent,
but are consistent enough, to have fresh real-time wattage displayed every 1 to 6 seconds.


My old efergy Elite display showed a lot less instantaneous power use than the TED.
The efergy had been calibrated at 480watts. Once power increased towards 1kW,
I could see a large power difference between the two units.
So, I used my current probe and voltmeter to re-calibrate the efergy at 700w.
I changed it's voltage selection from 240v to 260v.

This means that my earlier power use numbers are in error.
Depending on amount of time Sanyo was drawing 400-500w
verses the amount of time it was using 700-1400w.

Right now, I'm guessing my daily power use numbers over the last year,
were between 20 & 30 percent too low. Depending on the weather.

So, on cold 10 kWh days, I may have really used 12.5 to 14.3 kWhs (52 to 90 cents more a day).

It's hard to say which one is the most accurate, since I have no way to
calibrate my AC current probe.. But at least now, they are
displaying similar power use near the 700w range..



I'm betting the TED is closer. When I get the time, and it's not so cold,
I'll try to tweak the TED to match the NStar meter. Preferable at around
500 watts, which seems to be the average power during winter.

On average, since the Sanyo has been installed, our whole-house power use
each month, has been less than it was during the same month on the previous year (pre-Sanyo).

It seems like I'm not going to be able to use the Footprints software,
since my PC is in a room where the TED RDU (display) doesn't
receive data. It seems there is noise on the AC lines.




The XPF box in the center, underneath the breakers is a filter.
(I've read, it works to clean up lines for X-10 signals too).
In-Line Wired Noise Filter

It was suppose to cure the noise problem, by isolating the line
into my PC room, by blocking the noise from the breaker buss.
Not allowing it to get onto my PC room AC line.

Once installed, it actually worked a little. I was getting data packets once
every 10 or 20 seconds. Not really acceptable.

Then the sun went down and the lights came on.. NO DATA at all!
It seems, the outlets in the living room & in the PC room, that are used for lighting..
Are on my PC outlet.. TED doesn't like CFLs!!!


Stupidly, I started doing searches on TED communications problems..
Yeah they are pretty widespread. I'm not the first sucker to find out
about the CFL problem. One guy ran a long extension cord from his
breaker box to his PC room!

I'm thinking of the installing the RDU down with the MTU at the breakers.
Then, I can run a 85 foot USB cable upstairs to my PC..

Or, I can start installing filters on every single CFL in the house..

Oh yeah, I have to get rid of my good power strips that have noise filtering.
They eat up the TED signals..
