Hi!

We have some insights for you that should help!

The 50A sensors reach saturation at 75 amps but will decrease in accuracy as the current approaches this saturation limit. If you are seeing inaccurate readings from the sensors while the unit is drawing more than 50A could be the cause a reading accuracy issue.

Please contact support directly and we can look at the raw data and see if over-amperage is causing either of these issues. We’ve appraised the team of your update below as well. Please just reference your message with a link to this thread for reference.

Hi, Emporia Vue Energy Monitors need a constant 2.4 GHz WiFi connection to be able to transfer data to our cloud and the Emporia app.

[emporiacs]

If you’re in a split phase, common in homes in North America, the wire harness should be:

• black into L1
• red into L2
• blue and white and the neutral bus bar

The Gen 2 Vue Energy Monitor pulls only 2 watts when connected. You can terminate the wire harness into any size of breaker you have. You can use a breaker larger (or smaller) than 15A to power the Gen 2. Just make sure that 1. black is seeing L1 and red is seeing L2, 2. they’re in a split phase, and 3. blue and white are going into the neutral bus bar.

If you are going to tap into an occupied breaker larger than 15A (i.e. pigtailing), then the short black 14 gauge wire we supply in our accessories kit should not be used (it is only rated for 15A) and you will need to use the appropriate gauge wire for the tap. If the breaker is unoccupied then there is no need to use the wiretaps as you can install the wire directly into the breaker.

Remember: the wire harness is also responsible for half of the accuracy on the Gen 2, it reads voltage and powers the device, so it needs to be properly installed. Please follow the install guide and terminate the wires accordingly to the number of phases of power in your system!”

Hi,

That will not be possible. Anything plugged into the top ports of the monitor will be considered Total Usage by the system, so it will mess up your data if you have a circuit on top ports.

If you have a 100A circuit, by the 80% NEC rule, it should not pull over 80% of its capacity, so you’re looking at monitoring 80A.

The 50A sensors will read up to just under 75A, and show a flat line above that, so you can monitor your 100A circuit using 2 x 50A CTs, one per leg of that circuit and you should get accurate readings.

[emporiacs]

There is no solution right now for this scenario. This will be resolved when the 50A CTs are bi-directional or until we launch  custom settings for Excess Solar. There is no ETA for those features at present.

[emporiacs]

Custom Notifications are in the works for Smart Plugs, but there is currently no ETA.

[emporiacs]

Hi thanks for this feedback. We have relayed it to the team. We are working on this feature but currently have not ETA.

[emporiacs]

Hi,

Please contact support and so we can help confirm the configuration is correct.

[emporiacs]

Hi, we’ve relayed your feedback to the team.

For now, the raw data in kW and kWh is available with the CSV files, so which you can use to calculate the dynamic rates outside of the app.

You’ll need to need to use the hourly file, and apply the cost of energy for that time of the day. Once you do that for the 24 hours of one day, you can copy and paste the info to the other days.

 

[emporiacs]

Thank you for your details and questions. The statement we previously replied with “We do not recommend hooking into a breaker larger than 20 amps.” was erroneous. We’ve updated it to “we do not recommend hooking into a breaker larger than 15A with the included bridge wire.”

You can use a breaker larger (or smaller) than 15A to power the Gen 2 Vue Energy Monitor. If you are going to tap into an occupied breaker larger than 15A, then the short black 14 gauge wire we supply in our accessories kit should not be used (it is only rated for 15A) and you will need to use the appropriate gauge wire for the tap. If the breaker is unoccupied then there is no need to use the wiretaps as you can install the wire directly into the breaker.

More information: https://help.emporiaenergy.com/hc/en-us/articles/4408885176855-Wire-Harness-Breakers-larger-than-15-Amps

Now, for your first question: Yes, by “hooking into” we meant what you’re referring to (and as we’ve referred to above) as “tapping into.” We’re saying “hook into / tap into” mean the same thing because we’re just talking about the mechanical connection of a wire somewhere with those terms. “Tie-in” is another word you might see us use.

(We understand the confusion: that connecting the Vue within a pigtail may seem more akin to “tapping into” whereas connecting directly to a breaker may seem more akin to “hooking up.”)

Next, some additional context here for your next question about what’s okay to do with the red and black wires:

To hook the wire harness into a breaker (a.k.a what we might also say as “tap into” here) means to physically connect the wires into the breaker, inside the breaker, literally. You open the breaker slot and put the black wire from the wire harness there, and close it, making sure it’s properly attached.

If the breaker is occupied you need to pigtail, and that’s when you need the bridge wire we include. If it’s larger than 15A you’ll need to source an appropriate gauge of wire to meet the higher needs.

Additionally, if you have an empty dual pole 40A breaker to terminate the wire harness, excellent! And same as before, if need to pigtail you will need the correct wire gauge for the bridge wire which will not be the one included with your Vue.

If you have any other questions let us know and we’re happy to help.

Hi, we noticed this thread and some additional thoughts for you and future visitors below:

If you have a balanced 240V circuit, you can monitor it using only 1 x 50A CT. Solar lines and EV Charger lines, are always balanced.

If you don’t know if the line is balanced, you can make your own tests by adding one 50A CT per leg, turning the appliance on and watching on the app during the whole cycle of the appliance how much both phases are pulling.

We do not recommend using multipliers on sub-panel breakers since this can over/understate the circuit usage as sub-panel circuits are not symmetrical (balanced) in their load.

[emporiacs]

Hi, thanks for choosing the Emporia Gen 2 Vue Energy Monitor! The web app has the same functionality as the mobile app, except that the mobile app is required to onboard the products.

We’re happy to help further if needed, so just let us know.

[emporiacs]

Hi,

Balance is a calculation and we don’t graph calculations at the moment.

We’ve relayed this feedback to the team.

[emporiacs]

Hi, we’re happy to report that this feature is now slated to arrive this year!

[emporiacs]

Hi, thank you for this feedback. We’ve relayed to the team and understand where you’d like to see potential updates.

We are aware of and working on this feature request for ToU rates, but currently do not have an ETA.

For now, you can export CSV files and adjust the time slots that have a different price. This the approach many of customers take that works well.

Also, since the CSV files show the data in kWh and you can multiply the kWh by the cost of energy you have for the different time slots.
