I have three Emporia Vue3 monitors. One connected to my main panel with just the main CT Clamps monitoring the total power draw.
I have a second panel that goes from the main into the basement. I have another Vue3 connected there and I have a bunch of circuits monitored on that one. Then I have ANOTHER panel that goes from the Basement to a panel in the Garage where I have more circuits monitored.
First and foremost is that the math isn't mathing for the panels. 2.7A * 122.2V isn't 1386W, and I don't think I'm using 30kWh/day. The power company says I'm using about 3200kWh/mo and even that I think is a bit high. Since they upgraded my meter my usage has increased 60-80% which is ridiculous. I am hoping to get my meters dialed in so I can prove they are right or wrong. If they are right I am hoping I can figure out what's killing my usage so I can curb it. I currently have flat rate pricing so it's not a peak/off peak thing.

I would REALLY appreciate help getting my stuff straightened out!

Did you set the upstream devices correctly in energy dashboard config?

#

Do you have split phase or 3-phase power? If so, it's really important to match the voltage input and the CT to the same phase.

And I would say, start by focusing on the main distribution first.

I added the basement and garage ones months ago, and I don't remember what I did. I THINK I was trying to get the EV Charger circuit to show on kWh and may have messed with some settings.
The Main Panel I just added to the dashboard and that's it.

I'm in the US, and it's a typical residential two phase setup.

ok, I would start with ensuring that you have a correct grid sensor that measures total power so you have a ground truth

#

then if that consumes a lot of power you can start measuring individual circuits to narrow it down

wicked torrent Sep 3, 2025, 3:02 PM

#

On the main panel I only have the two big clamps connected to the inputs. So that should give me the total power usage. But someone pointed out that the math isn't right.
I swapped the inputs in the yaml and everything went to zero. I was going to swap the actual clamps just to confirm, but I THINK they are on the correct lines

#

I just don't like playing in the box so I've bene putting it off

real tree Sep 3, 2025, 3:04 PM

#

if you dont have a ground truth you're flying blind

#

the sum of your circuits can never exceed total grid import (assuming no solar)

wicked torrent Sep 3, 2025, 3:05 PM

#

No solar

#

I got these to monitor the power, so I guess I don't know how else to measure it to compare.

#

could ask an electrician to hook it up correctly for you

floral holly Sep 3, 2025, 3:30 PM

#

Besides clamps you should have an input for the voltage. That input should match the correct clamp.

And yaml, what yaml?

wicked torrent Sep 3, 2025, 4:28 PM

#

Yes, there are two wires connected to breakers, one on each phase that match the clamps.

#

YAML for the ESP32 code for the Emporia Vue3

Ahh, you run custom firmware. Pretty important detail 🙂

And your config is quite small compared to DigiBlur. You only use 2 of the 16 inputs?

If you're sure the CT and voltage input match, I would say it might just need calibration.

wicked torrent Sep 4, 2025, 7:05 PM

#

Yes, for this one I'm only using the two main clamps, I have two other units where I am using most of the inputs.

#

How do I calibrate?

swift copper Sep 5, 2025, 12:27 AM

#

Are you in a duplex? When I was, my new neighbor moved and my power using skyrocketed. Long story short, I was being billed for his power usage. FYI.

wicked torrent Sep 5, 2025, 4:50 PM

#

No, a house. Wouldn't surprise me if my one neighbor is syphoning power though. Awful people.

#

That's why I need to get these things working correctly, my bills have skyrocketed this year.

wicked torrent How do I calibrate?

There doesn´t seem to be a build in way in the integration. But you could just scale the power.

Connect an resistive load you know (or can measure otherwise) and just add a multiply filter to the power entry so it will display the correct value ([mutiplication factor] = [correct value] / [current value])

wicked torrent Sep 7, 2025, 5:36 PM

#

So like plug in a 13w Lamp?

#

Then 13w / (whatever it's showing) = multiplecation factor ?

floral holly Sep 7, 2025, 7:00 PM

#

13W does´t sound like incandacent. So rather a 60W bulb or something like a toaster

#

But I don´t know why it's so far off. As the integration has nog calibration for it and it seems so far off

Are you connecting the Black voltage sense to Line 1 and Red voltage sense to Line 2? White to Neutral

rose olive Sep 8, 2025, 9:28 AM

#

Your supply may be 2 phase with both lines in phase Your config needs to have 0Deg for phase offset

floral holly Sep 8, 2025, 9:55 AM

#

@rose olive Phase angle (luckily) isn't part of the config but measured from the voltage.

Can you flash the Main unit back to Emporia FW. With no small CTs connected you should see 100% in the balance and total usage Watts will be the power of that board

I'll have to check. The electrician connected it, and he used the docs when he connected it.

I am not sure if I can flash it back. I'd have to look into that.

rose olive Sep 10, 2025, 4:46 PM

#

I have a backup of the Vue 2 original FW, but if I recall you have the Vue3. Someone may have FW if you do not have a backup. Try other servers like digiblurDIY

#

You definitely need to have the white wire from the Emporia Vue connected to neutral common bar. As a reference.
