***Update on TED 5000***
- was up in the attic insulating and heard a distinct buzzing noise.
- found an old circuit leading to an unused, unmarked, outdoor Sodium lamp fixture with no switch, junction, etc.
- the bulb and fixture had been removed and a plate put over it.
- HOWEVER, the ballast was still live. And buzzing loudly.
I removed it and had a eureka thought that the old buzzing ballast was probably wreaking havoc/interference on my power lines in the house - foiling my past frolics with TED.
Dug out the old TED 5000-C, and voila! Gateway and MTUs connected and I am currently monitoring my whole house energy usage. (Still don't know why they don't utilize something in addition to PLC for communications, but I guess someone may have mentioned that to them already...!)
It's pretty darn sensitive, too. Turning on 300 watts of dining room fixtures is reflected immediately and accurately in the TED data. Unplugged the 30w AT&T Microcell, and saw the power usage drop in step. Seeing the curve of Solar generation too on the second MTU, which then adjusts the data to perform Net usage calcs. (jeez, Solar gen so meager in a New York winter...).
Integrated with Google PowerMeter. There's a nice iPhone app too: Ted-O-Meter. Would be GREAT to have this interfacing with Vera. Now to get rid of that 10 year old electric dryer...
Old Post ++++++++++++++
FYI. I have the Ted5000 (5002-C). Tried to integrate it into my panel (which also has a co-generation inverter connection to my Solar panels).
After weeks of trying, never got it to work reliably. Seems to be too much noise on my power lines. Between the CFLs, Inverter, Dimmers, etc. I think I saw a reliable reading once...
TED users in newer homes seem to have much better results. My 2 test houses were a 100 year old brownstone and a 40 year old beach house.
My TED is for sale for $200. It's model 5002-C (http://www.theenergydetective.com/ted-5002-c
). Brand new!
