Interference confirmed...I hope


OK...so I think I've confirmed the interference.  Above is a 36-hr graph....the inline filter was installed by 19:00 hours. Check out 7am yesterday versus 7am today...SIGNIFICANTLY lower peaks.  Today's peaks max out around 17 kW while yesterday's peaks reached 29 kW.  I'm guessing the interference may have been a result of the heat pump supplemental heat strips as it seems the extremes were exaggerated as you can see that the smaller loads appear to be consistent.  I'm a little hesitant to declare victory as it's 36 degrees outside today. Well...the past two days it was ~25F.   Well, that 10 degrees makes a difference in how/if the electric heat operates, as I explained yesterday.  So, we'll see, I guess.  This weekend show lows in the 20s again...

TED Interference and Filter

OK...so I had suspected there was some sort of interference with my TED unit.  This main reason came about because I was noticing some loads from TED showing >40 kW.  Well...if I add up all my loads in my house, I don't think I get 40 kW.  So I ordered the suggested "in-line noise filter".  However, instead of ordering it from www.theenergydetective.com website (which was ~$14 for the filter plus ~$16 for fedex to ship it...yeah, no sh*t)...I ordered it from X10shop.com.  BTW...X10shop.com was prompt, quick, and they had a good price ($9 for the filter plus $3 for USPS shipping).  Kudos to that place.

Anyhow, so I installed the filter which was a pain...if you follow my lead, make sure you splice on some extra wires because the wires are really short from the filter...like 3" long.  The max distance I had was probably close to 12" long.  After installation, I had to reset some of settings, it is working great.  The TED is much more responsive to load changes and the communication light on the side is now blinking much more consistently (this is an indication that it is receiving a signal from the MTU in the breaker box).  I'm thrilled!

So...I'm just going to have to wait and collect data to see if those AM loads I ranted about earlier are just fiction (I hope!).  Otherwise, it could despair...
