The TED5000 is a measuring device that you connect to your panels and<br>
measures your power consumption on each feed. Depending on where you can<br>
install the CTs, you might need at least two (one per breaker panel). The<br>
box is a linux device and measures your power in 1-second increments. I<br>
have a cron job that I use to pull off the statistics of the per-second,<br>
per-minute, per-hour, and per-day calculations.<br>
<br>
You can also program the TED with your energy rate(s) and it will compute<br>
your monthly bill.. For me it's usually within a few dollars of my actual<br>
bill from GP.<br>
<br>
For a while I had a script that would insert the data into a mysql<br>
database and I had a RoR app to allow me to generate graphs and stuff.. I<br>
did this when I was contemplating converting from my current standard rate<br>
to a ToD metering and wanted to know if I would win or lose. But the<br>
data quickly outgrew my mysql; so I've just been collecting the raw CSV<br>
data and figure one of these years I'll look it over again.<br>
<br>
Just my longer $0.02 (now that I'm actually at a keyboard).<br>
