I've been trying to update the Utility Settings to reflect the tiered system my current provider uses and can't seem to get the unit to accept / use the change.  

Go through the usual process of Settings -> Utility Settings, then walk through the tabs choosing Tiered as the plan type.  The provider has three tiers and I fill them all out then fill out all the rates and other relevant information.  Last, I write all of it via the Write to ECC -> Update button and the device goes through the motions and it appears the update was successful.  

However, on the Live Dashboard it still indicates the Plan Type as Flat.  Have rebooted it, but not yet tried Resetting to Factory defaults.

Is this a bug ?  

The firmware the unit is running shows to be:
( via Help -> About )

ECC Version:  1.0.696
Footprints Version: 1.0.700


It seems that TED doesn't play nice with Chrome.  No matter how many times I modify the settings and update the ECC, nothing happens.
Switch over to FireFox, however, and the changes go in on the first try :|

Have Ted 5000 set up in a sub-panel feeding a rental Apartment in my house. The electric rate i pay is .15 per KWH. At end of month the total cost of electric figure in History comes up incorrect.  Total monthly cost for KWH used in history had been correct for last few years. Only have this problem in last two months since installing new Window 10 operating system. Does anyone else have this problem and know how to correct Huh

Generally speaking, you only need to monitor one 'side' of a domestic 240V circuit, so you will only need 3 CTs to monitor the 3 double breakers, with the respective input channels set up to double their readings. Also, breakers are rated by the total current which is needed to trip them, so the CT on one 'side' need only be rated for half the nominal breaker current. You would therefore need a 20A CT on your lower A/C breaker and a 60A CT on the upper one. I can't read the rating of the Pool subpanel breaker with certainty, but if it is > 40A and < 120A you would also need a 60A CT on it.

Hey Guys,

I'm trying to configure my TED Home Pro order with the proper spyders and one thing I'm confused with is which spyder I need for stuff like the A/C which has two breakers that are sorta connected to each other (Sorry if my terminology is way off). 

For example here is my breaker box for the pool subpanel and two central A/C units I have:    Could I get away with three 60A Donut CTs since the highest I see on anything is 50A?  or do I need six 60A Donut CTs to monitor those 3 loads?

A couple of things:
1) To get meaningful power readings from a Spyder Channel for testing purposes, you need to apply a steady load to it for 3-5 minutes, and ignore (at least) the values from the first and last minute. Spyder channels are supposed to average over a minute, but my experience is that their readings may not totally settle in the first full minute after the load changes.
2) The specified accuracy of the Spyder channels is relative to full scale - you can't draw useful conclusions about potential problems if you are applying a load near the bottom of the channel's measurement range.
3) You also won't get meaningful power readings from a motor circuit (I assume, from the current/power draw, that you were looking at the AC circulating fan load) by separately measuring AC Volts and Amps with a multimeter and multiplying them. It is the 'reactive load' issue I alluded to in my last message. The voltage and current are not in phase with each other. Indeed, in the extreme case of a frictionless motor turning a flywheel at constant speed with no mechanical load applied to it, they will be 180 Degrees out of phase, and no electrical power will be being drawn at all, even though the separate measurements of Voltage and Current will not be hugely different than when power is being used by the motor to drive a moderate mechanical load.

For test purposes, you should, if possible, use a large, steady, resistive load (electric oven, electric hotplate, electric space heater, immersion heater, microwave oven).

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.

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
