How do you identify a 120 or 240V device in the Power Meter?

Off topic slightly, but how do you guys know if it is 120 or 240 without looking at the mains reading under the sense monitor setting while the device is running?

@billlokey Apart from “knowing” the device a general cue is that a rapid “on” in the Power Meter of more than 15(A) x 120(V) = 1,800W is usually an indicator of a 240V device. Some devices might draw up to 20A@120V if the circuit allows (2,400W rise/fall in meter) but those are rare.

Technically speaking, any device drawing more than 1,800W at 120V on the lowest code-compliant gauge of wire under typical conditions (length; insulated walls etc) is going to overheat the wire eventually and cause problems (=melt). Hence the code.

I understand what you are saying, and totally agree with you. My problems is frequently I have multiple high draw single leg items on different circuits (hair dryer, and toaster for example), without watching the meter in real time it is hard to see what happened when going back to review. I am still in my first month so not many detections. I just didn’t know if you guys knew a trick I didn’t. When scanning back through the power meter you are unable to view the watts/amps being read off each ct.

My “trick”, because I have 2 Senses (with solar CTs) on the same Mains is to use a Sense Solar CT on one Main.

Watching your “mains” in the app for changes to each “leg” while a device cycles on or off is the easiest. II t is time consuming but helps to have alerts set.
