Emporia Vue2 dual breaker monitoring and deleting old data

- This video goes through and shows how some dual breaker devices (clothes dryer, AC compressor, oven, furnace, etc) pull the same Watts per phase while others do not as shown in the app. In the app we'll walk through and show how to monitor a dual breaker with a single sensor if you want and delete old data to keep overall power usage calculations as accurate as possible.
That was helpful! I needed to do the same thing. But i thought the clear data was going to clear everything at once. I’m glad to see it doesn’t. Thanks
Nice video showing exactly how to switch from dual leg to single leg monitoring and keep your historic data correct.
One way to tell if you need single or dual clamp for your 240V is to look at the wiring at the load / appliance. Dryers and Ovens use the 4 wire outlet - 2 hots, neutral, ground. Other 240V loads like AC compressors, well or pool pumps, hardwired EV chargers, and hot water heaters don't typically have a neutral wire. If the load doesn't have a neutral, you can use the single clamp. Anything with a neutral (including sub panel feeds) will need the two clamps as the load can be unbalanced between the phases.
The reason you are getting different readings on the separate phases of your oven/ cook top is because the top burners consist of two 120 volt single phase circuits , NOT a single 240 volt 2 phase circuit, like the oven. The top may be used favoring certain burners that are on one phase rather than the other. I recommend using two CT sensors on electric oven cook top units.
The reason your oven or dryer uses more on one leg than the other. Is because the burners on low only draw 120 volts but on high they draw 240 volts. Same thing goes with the dryer one leg could power the motor and parts of the heating element and the other leg could just be the heating element. So basically it comes down to what part of the appliance is used a 120 volt and what part is using 240 volt.
I hadn't thought of this and can't find it mentioned anywhere else on the internet, but this makes perfect sense. I'm awaiting my Vue 2 with 8 sensors and had been thinking I could just use one clamp each to monitor my 240V stove and washer/dryer. I guess that won't give as accurate readings!
Would love to see an updated Review Vid!
Made a quick one a week ago, hope it helps.
Do you multi multi panel install and software setup, and use video? Thanks.
I have a panel outside with a Vue2 that feeds a sub/child panel inside that has 2 Vues. 3 total Vues in use. The outside panel has 3 sensors to monitor power consumption on 3 AC Compressors. This AC panel then feeds a house panel that have 2 Vues monitoring 34 breakers. The app currently understands child Vues, but it does not correlate power usage of side by side (coexisting Vues on same power feed) Vues like the two I have in the sub/child panel. Last time I spoke with support (a few months ago) the side by side option in the app was supposed to be added this year.
How's it working out?
Everything is working as it should and it appears to be very accurate. Biggest surprise was the amount of electric the water heater is taking. Roughly 1/3 of my power bill and I don't have it set at boiling. Makes me think of switching to instant water heater or a gas tank.
My biggest issue with the app is that you can't combine monitors. I have two 18 sensor monitors on a single panel. The excess power used by a single device is listed under 'balance'. So when I look at power usage, I see double what the usage is. For example, one device 1 I'm monitoring circuit breaker A and that uses 5W. On the same panel (hooked to the same incoming feeds) I have device 2 monitoring breaker B using 20W. On device 1 I see breaker A using 5W and then 'balance' using 20W for a total of 25W usage. On device 2 I see breaker B using 20W and a balance of 5W for a total of 25W. So it looks like I'm using a total of 50W when you look at usage in the app when in fact its only 25W.
They are supposed to come out with an update to the app to allow you to combine 2+ monitors for a single incoming feed, but there is no ETA on it. That will greatly help determining actual usage without manual intervention.
It is nice to have the 'balance' on a feed though so you can see how much total power is being drawn outside the individual breakers you are monitoring.
Change to a heat pump water heater. You’ll use a fraction of the power.
@@forayfog2276 I'm in the same boat also - have two Vue 2's and I'm using all 32 clamps in one large panel. Waiting for the app update to bring these all into one single list. Emporia did just update the app to add subpanel nesting support, but everyone is still waiting for single list integration of Vues/Devices, and better handling of 240V circuits (combining dual clamp, automatic doubling of single clamp). Supposedly due out this Summer (2021).
@@forayfog2276 You can look into a heat pump hot water heater as an alternative. There are also heat pump dryers now as well and they do not need a vent, just a water drain line.
