@emporiacs Emporia has been promising the bidirectional update for years, is there some actual planned date for such an update, or is it just a wish?

Just would like to know the reality of it all…

Thank you

If the seal is already broken, I would say, have at it if you want. Just be mindfull that if they decide to come by and add a seal later on, you may be locked out of your device 🙂

Next best solution add a small electrical box on the side.

It measures the actual voltage of the line, and is also supposed to measure the power factor, although people with 3 phases in Europe are reporting issues with that.

It looks like you should be able to put the clamps around the busbars coming out of the main breakers.

There may not be enough space on the left of the left bar though….

You should not need a multiplier if you have a CTs on each wire.

Are the values detected by the Gen2 CTs on your Main phases different that the values reported by the Linky?

For solar, make sure of where your solar system is measuring.
Most solar system with a string inverter measures the Solar panels production, which is DC power, and before inverter.
The Gen2 will measure AC power coming out of the inverter and into the house panel, and that can be almost 10% less power than the Panel DC power.

Not sure what you are asking, but the browser web portal of your emporia Vue device uses the same credentials as the APP, and that you created when you first installed your Vue

You need a CT on each Phase wire for accurate reading

If you get no report from a sensor even after unplugging and plugging it back, the first thing to do is to determine if it is the port that is dead or the sensor.

For that, swap a working sensor with the Non-working one, then check if the problem follows the sensor or stays with the port. And I mean actually unclamp a working sensor from its circuit and clamp it on the circuit of the bad sensor, and vice versa. The Circuits must stay connected to the same port on the Vue, just the sensor being used need to be swapped.

The Vue calibration references the port, not the sensor, so no issue swapping sensors around, as long as the circuit being connected to the port does not change

If the problem follows the sensor, then the sensor is bad (I had one died on me once), if the problem stays with the port, then there may be a problem with the port of the Vue…

Without the detailed specifications of the Emporia sensor, it is impossible to tell.

Have you asked them to provide the detailed specs of their sensor?

Can Emporia please give us an Honest answer on this.

From the very beginning we were told the CT used on the solar input are bidirectional, and that eventually the Software would be able to read the sign and report it correctly.

It has been years and still no change on this issue which is a major drawback for solar users.

@emporia, have you given up on this feature, or is there a real short-term chance it will be done?

Just tell us the truth 🙂

Appreciated, and thank you for such an otherwise great product!

I agree, Smart breakers is the way to go and would allow us to create a truly smart Electrical panel.

Ideally Smart breakers should not just report (Volts, Amps & power factor), but should also be actionable remotely, so you could turn them ON or OFF remotely.  This would also open the door to the creation of scenarios like turning breakers ON or OFF automatically in a critical loads panel during an outage.

I hope it is at the top of the list  🙂

The CTs on the main leads are bi directional, so in the data file, energy exported to the grid is negative, and energy imported from the grid is positive.

Using a tool like excel, you can separate the positive values from the negative values.

The Total Energy Imported from the grid is the sum of all the positive values

The Total Energy Exported to the grid is the sum of all the negative values

Can this Amazon unit record overtime, and if so at what interval, for how long, and how do you download the data?

[scrambler]

You would first need to know how the two panels are interconnected, to know if you would need to just add CTS on the solar lines, or also move the 200A CTs .

I am also not sure how long you can extend the CT wires, you should ask Emporia that question.

If you can use a 50ft extension you could always install CTs on the Solar lines, making sure to orient them opposite as the Load CTs. But the question above needs clarification to see if you can still get a proper Net metering reading or not

If you cant extend that far, then you would need a separate Vue, and monitor the solar separately from the rest

[scrambler]

I believe the 200A CTs are what is shown in the App as the Net production
