    Also, you may want to check the Solar Supplement guide.  It shows the two ways the solar is typically connected – and monitored with clamps…

    If you don’t have an Emporia Vue 2 circuit clamp on the solar, it will be an unmonitored circuit and behave as you are seeing.  The inverter and Emporia don’t speak to each other, so you need a clamp for the Vue 2 to know what your solar is generating.  From your screen shots, it doesn’t look like you have that?

    As mentioned on the other thread, a photo of setup would be helpful since there are a few ways solar can be wired (and monitored).

    Based on what you describe, you do have an unmonitored circuit – your solar.  This makes perfect sense why seeing a green (generation) balance during the day, and zero balance at night.

    There are a few ways your solar could be connected.  If you have it backfeeding a breaker in your panel, you would put a circuit clamp on it and flag the circuit as solar.  When you do this, you balance will also be zero (or thereabouts) – regardless of day/night or generation amount.  You will see the exact solar generation broken out separately, along with mains and net.  Alternately, if you have your solar line-tapped, you will see what you are describing since there is no clamp on the solar itself, so the software is displaying this as an unknown surplus (balance) during the day.

    A photo of how you have your clamps and solar would likely allow for a better explanation, since there are several ways you have things installed.

    With your balance being green (and not blue), that indicates that you have unexpected production of 3.268 kW.  Your net is also green, indicating you have 1.897kW going back to the utility.  So it appears you have some un-monitored solar generation in the system.  Or one or both of your mains clamps are backwards (assuming this is a US 240/120V system).

    +1.  Still looking for all those things stated to be in the upcoming Spring (then Summer) update.  Everything mentioned above, plus support for multiple Vue 2’s in the same list, a fix for the Amps issue, etc.

    I’m similarly disappointed with the useless (for me) new features, and no (apparent) attention to promised fixes.  I’m pretty sure no one will rely on the new load control with the smart plugs until those power outage control glitches are fixed also.

    What is the current status on addressing the known faults and usability issues?  Thanks!

    If your panels are close (or relatively so), in the absence of a software solution, one thing you could do is parallel the CTs going into one of the Vue’s.  Get a 3.5mm Y audio cable, and combine the CT’s from the different panels.  May need some short audio jumper extensions also.  You do need to make sure you combine the same hot phases.  After hooking up this way, your one Vue2 will show you the total utility consumption, without any math.  The balance figure for that Vue 2 will then equal the negative balance total from the 2nd Vue2, which will no longer show any mains power since the mains CTs aren’t connected to it.

    The other way to do this is to clamp the main Vue 2’s leads around the 400A feeders.  That is, if the clamps fit, have enough wire length, and are comfortable accessing that area with the high power.

    Picture came through fine this time.  Turn off those un-monitored breakers and you will surely find what is consuming that extra power.

    Believe the specs are better than +/- 2%, in the FAQ here and posted also.  That’s my observation also – with the error mostly in the CTs and not the Vue 2.

    If you were trying to post a photo, it didn’t come through.  So don’t know what your mains are showing, but unless your total draw is 18.5kW (2% would be 370W), your balance is pretty accurate.  That’s the magic of this system – finding those unexpected draws.

    If you don’t have CT’s on certain un-monitored lines, start turning those breakers off and you’ll find the power consumers – which are could be a combination of devices and circuits.

    The balance is the power consumed by all the circuits not monitored by CT clamps.  For example, if you have the Vue2 bundle with 16  CT clamps and your electrical panel has 24 circuits, the balance would be the power of those unmonitored circuits (24-16=8 circuits in this example).

    The manual is very detailed and covers multiple install scenarios based on how full your electrical panel is.  If this is a US installation (split phase 120/240V), the best accuracy is achieved by using a 240V dual breaker and connecting the red and black wires to each respective phase.  Blue and White then go to neutral.

    May want to refer to the install guide – this is covered on the 2nd page…

    emporiaenergy.com/installation-guides

    But red is the 2nd hot line (for US 120/240V installs), and blue is used for 3 phase monitoring.

    Sounds like you have Ground Fault or Arc fault breakers.  The Vue2 clamps must only be installed over the black (hot) wires.  If you clamp both the black and white (neutral wires), the positive and negative current flow will cancel and you will see zero power/current.

    Duplicate question – see below.  Sorry, this is not possible with the Emporia Vue 2 hardware.  If your main breaker is off (due to generator safety interlock), there is no current flow in the Vue2 mains clamps so it cannot detect when grid power is restored.  Need an electrical field sense device to do this.

    Regarding Amazon Alexa, did you install the Emporia skill?  If not, that is required.  Search for the ‘Emporia Energy’ skill, install, and link with your account.

    I had a similar problem.  In my case, I have 2 Vue2’s and  1 had gone offline for no reason.  Even power cycling it would not restore operation.  Ping would work ok, so knew WiFi was fine.  Did try to re-setup WiFi a few times per Emporia support, but it didn’t solve the issue.  After some troubleshooting, I found that I had to power cycle my WiFi router.  After that, everything has been fine.  I don’t know for how long – but it has been working ok for a few weeks now.  Granted it worked for several weeks before going offline.

    Perhaps try a full power cycle of your WiFi router (instead of forcing disconnect) and see if you have any different results.  I’m guessing this may be something related to NAT and Emporia not liking some local port numbers that the router assigns, but this is only a guess.
