      I have a question about how the amps measurement is reported both for the main system and the expansion module. For example I have one CT hooked to one leg of my hot water heater which reads 5000watts when energized. I have the multiplier on two. I look at the amps and it shows 43 amps which appears to be double the actual load. (30 amp breaker). Same question for the main clamps; is it also reporting double the actual 220v amps?

      Hello @cwajciec, thanks for joining the forum! We currently have a bug in the app software as it relates to the multiplier for Volts. While the multiplier correctly multiplies the Watts, it incorrectly multiplies the AMP’s. The development team is currently working on fix and we hope to have it corrected soon.

      Do you have an ETA on a fix? I just got my 1st Vue and was about to half all the multipliers until I found this

      I suspect this is releated to the bug with the multiplier. My ‘Other’ catagory shows a negative percentage. My dryer is on a single sensor with a 2 multiplier. Since it hasn’t run is the last serveral days I think this is possibly the cause of the negative percentage.

      @EddieVan @jbkatk we are working as fast as we can to remove the multiplier on Amps.   We don’t have a date yet but will get it released just as soon as possible.

      I have the same problems here (reported the double Amp problem somewhere else in the forums) and I also observed the negative values on the Other (the dryer reaches nearly twice the power measured on the mains.

      Thanks, Denis

      Just wanted to add my voice to those wanting this bug fixed.

      I installed my system yesterday and noticed the problem immediately. Mainly because my EV also shows the incoming amps and I can compare that to the outgoing amps from the Emporia system. It does appear that kW are calculated correctly, but it looks like you are dividing by 120 instead of 240 to calculate the amps on the double breaker circuits. It is difficult to see what the true usage of power is when the circuit box is a mix of 120v and 240v circuits.

      It also appears that this same problem occurs on the incoming power, which surprised me a little, since there is a CT on each leg. When I changed the multiplier for my EV back to ‘1.0’ to see if that would give me the correct amps, my “Balance” value shot up. I assume the Balance value is a subtraction of all measured power from the incoming power. If that is the case, then it appears that you are dividing the incoming watt measurement by 120v to calculate amps, but that should really be 240v since the potential between the two incoming legs is 240v (each 120v line is 180 degrees out of phase with the other).

      Anyway, it appears that you are aware of it and hopefully get it fixed soon. Just wanted to throw my 2 cents into the discussion.

      @JohnL Thanks for the feedback, we are aware and working on a correction.
