    Yes, if you are seeing correct real power on the mains, but not on the circuits, I’d agree that is a bug.

    Sadly, Emporia has not been forthcoming with any bug fixes or feature improvements to the Vue 2.  We’ve been waiting for combining of multiple Vue 2’s, as well as better handling of 120/240V split phase circuits for the US.  Going on a couple years now when these things were promised to be coming, but never happened.

    Wire order does not matter.  That said, multiple people have reported 3 phase problems with the Vue 2.  Their claim is that it is falsely measuring VA (apparent power) and not W (real power) when in 3 phase mode.  This sounds exactly like what you are seeing with the high idle draw of your range.

    Is it a bug or a feature, that is unknown.  In many cases 3 phase is used for commercial power, and many commercial utilities bill for VA and not W.

    What part about the approach is it that you feel doesn’t work?  They measure voltage, current, and phase angle – which is all used for real power determination.  Believe this has been shown to work well for everyone with split phase 120/240V setups (or 230/240V single phase), but there are some people saying there is an issue with 3 phase.  Is that your scenario, or do you feel something else is amiss?

    Consumption from the grid vs. excess surplus Production back to the grid.  That is normal if you have grid tied solar, and don’t consume everything you produce.  If you don’t have solar, something isn’t setup correctly.

    The C port is only used for a 3 phase setup.  If you want to measure bi-directional power, that only option is using a 2nd Vue – and the mains clamps.

    Emporia has claimed this could be added at some point (also an issue for solar and night-time vampire inverter / microinverter draw), but this is going on 2 years now and they don’t seem to be addressing system shortcomings – let alone new features.

    Well, depends.  Emporia does not currently support bi-directional power flow on the circuit ports – only the mains.  If you have a dedicated Vue 2 for this, use the mains clamps (A & B).  That will show you the power in and out.  If you are trying to do this on the circuit clamps (1-16) on an existing Vue 2 (already using the mains clamps to monitor the mains), you will only be able to see absolute power flow on the circuit ports.

    There is a link on the Emporia web site to the Energy Star info.  Looks like 5W idle, but they also list the power loss when charging also…

    That is correct.  Yes, if you don’t care about knowing the loads individually, you can pass as many hot wires as you can fit through the circuit clamps.  In this way it sums up the two currents.  In my case I have 2 Vue2’s, so 32 circuit clamps, but more than that in my panel.  So for a couple circuits, I run two hots through a single clamp.  Has to be on the same phase – doesn’t have to go to the same breaker (even if you have those fancy breakers that accept two hots).

    Make sure the 2.5mm jack is plugged in securely – especially when tucked into the electrical panel.  I’ve found that some of mine plug in better than others.  Some people have wrapped around the perimeter of the Vue2 and the jacks with electrical tape to stop them from pulling out.

    Also, I’m not sure what happens when you move a CT from one 120V phase to the other one.  It may not be smart enough to deal with that, and you might have to re-run setup.  That would be a question for Emporia chat – they rarely reply here.

    Not all sensors need to be used.  Plug in what you want to measure – mains only, circuits only, or a combination.  If you want to know your full household draw, you need the mains.  Any circuit sensors are then optional for more info on those exact draws, and the app will show you a balance figure for the unaccounted for draw of the unmonitored circuits.

    I guess while you are sorting out your issue, make sure you are not using the schedules of the EV.  That will influence how and when the car wants to charge, and may complicate things.  I’d set the vehicle to charge immediately for now, and use the emporia scheduling if needed.  Once you get the modulation working, then you can use the vehicle scheduling – if you require that function.

    Yes, there is a web app.  https://web.emporiaenergy.com

    No.  This is designed for basically easy residential charging.  Its not like commercial ChargePoint devices which have access control, billing, etc.

    That high-level topic is locked, but you create new issues in the subtopics beneath it (hardware / install, app, bug).  Not that Emporia will reply (they haven’t been active here in a long time), but other forums members will likely.

    It sounds like you have a Bluetooth issue and not a Starlink WiFi issue (so far).  You shouldn’t have to do anything with Bluetooth on your phone.  May want to reboot or turn off and on Bluetooth on the phone.  Sometimes that basic step solves a lot of problems.

    Also, understand the RF signal is not very strong.  If you already have your Vue 2 sealed up in your metal electrical panel (and don’t have the antenna on the outside), you could have some signal issues.  I’m guessing that isn’t your problem, but just worth mentioning.

    And finally, a dumb question.  You are sure the Vue 2 has power and is running?
