In trying to zero in on the problem.  I pick the circuit for the AC Furn.  While watching the spyder load at it's peak the spyder read .304KW or 304watts and at that moment I checked the amp load of the circuit with a multi meter and the amp load was 1.5 amps which equates to .180KW or 180 watts.  I am using a 60A CT for this circuit which the spyder spec say that a reading below 200W will record as zero  Not sure why it is reading anything.  I am using a 60A CT since it is a 60A breaker.

[MTU]

Up until now, I think that we have been implicitly assuming that the main MTU/CT is reading correctly and the Spyder Channels are reading high. The possibility exists that the Spyder totals are correct and the MTU is reading low. Do your Spyder values match the load that the individual circuits should be drawing, when they are drawing it? When a heavy load (electric heater, oven, microwave, ....) is turned on, do both the relevant Spyder Channel and the MTU indicate the same, approximately correct (i.e. consistent with the load's faceplate wattage), increment in power flux? If not, does the Spyder reading increment seem high or the MTU reading increment seem low?

In my experience the MTU/CT combos are pretty reliable unless the CTs are not properly applied to the power feeds which they are monitoring. Assuming that you are using the standard 'clip-on' main CTs, are the clips completely closed, and are they both 'facing' in the same direction?

Out of interest, are any of your loads very reactive (e.g. high-power motors) - I believe that Spyders may overread on reactive loads (VA value rather than true wattage)?

I am only using 60A CTs and measuring all circuits separately.  Do not have any 20A checked.  Mult is set to 1 on all circuits.  Only one block checked for each circuit in the graph description.  Have also switched one of the spyders just to make sure it was not a bad spyder

- got a used Plug-in Hybrid Chevy Volt.  How many kWh extra per day does it add to my home use?  I have no good idea, I can't get the Ted5000 to work on that panel.
 Wild guess @ average 15 electric miles per day = about 5 kWh per day added to home use.  When away traveling, this is not the case though, the vehicle is either at the airport or driving with me.

If your wild guess is close, it sounds pretty good.  At least at the rates we have around here.  What amp breaker do you need to plug that into?

[about 400 to 500 watts just for my in-house server farm]

I run about 400 to 500 watts just for my in-house server farm, add in appliances (fridge, freezer, DVR, etc) and my daily average usage when not at home is double that.  I'm not really concerned about tracking down the small loads, more interested in looking for unexpected large loads and trend over time.

I retired one server and replaced the full-size Dell with a small XeonD server and solid state drives.  Now I'm down to about 300W for the server farm, including the power drawn by the PoE switch (feeds cameras, etc so they don't need their own wall wart).

For what it's worth, a few added comments from my end as to what I've been up to on energy at my house, since starting this poll:
- got my solar and my batteries all sorted.  No appliance efficiency improvements that I'm aware, but (maybe) some improvements I think in overall solar kWh per day harvested.
- got a used Plug-in Hybrid Chevy Volt.  How many kWh extra per day does it add to my home use?  I have no good idea, I can't get the Ted5000 to work on that panel.
 Wild guess @ average 15 electric miles per day = about 5 kWh per day added to home use.  When away traveling, this is not the case though, the vehicle is either at the airport or driving with me.
- no really strong progress on home "baseline", so I am still  between 3-4 kWh per day when away traveling, though I guess recently there are signs that I can get this back down below 3 kWh per day (I forget where I was with this when I filled out the poll).  Maybe even below a "measured" 2 kWh per day if I was really into it.  This is just a matter of more carefully going through the house, if I feel like it, and turning off or unplugging certain small items.  I say "measured" because with the TED5000 not working on that one panel, I'll assume that my actual use could be a bit higher.

[not]

Something is definitely wrong. Have you got any of your Spyder CTs set up to double the reading when they shouldn't be - e.g. monitoring both 'sides' of a 240V breaker and doubling one or both? Have you got any of your logical Spyder Channels set up to include more than one CT, with the same CT included in more than one logical Channel? Have you got any of your Spyder CTs shown as 20A in Spyder setup, when they aren't?

Correction (1/22/18 09:10) - the last question should be the other way round, i.e. "Have you got any 20A Spyder CTS not shown as 20A in Spyder setup?" The opposite error I originally suggested should actually give lower readings.

I am monitoring all the circuits in the panel and realized that the spyder totals would not equal the MTU however I was surprised to see that the spyder totals were greater than the MTU. At the last comparison I did the MTU total for today was 42.3 KWH and the spyder totaled 59.9 for the the day.

[direction]

They are totally independent, and cannot be expected to 'track' perfectly (even without allowing for the specified accuracy of the hardware), though the direction of your discrepancy is unusual, even if you have Spyders monitoring all your loads, since Spyder channels read zero at low positive currents and will consequently (usually) accumulate lower totals over time than the MTU(s).

Is the information(KW,KWH,MTD) recorded by spyders totally independent of the information recorded by the MTU?  When I add up the recordings by the spyders they always total more than what the MTU has recorded.

Hello, I just read this thread.  I'm glad to see somebody creating an editor.  I've had several corrupt data days in the past usually with the systems just reading zero for several hours/days, but last week the system claimed I used $2602287.32 in a single day.  I would love to fix this bad data.  Please send link to download editor and where donation or paypal can be sent.  Thanks in advance for your hard work to create a product/tool to enhance the TED Pro product.
