Power usage for July 19, 2017. These readings are from my second Efergy hub. The X axis shows time of day (midnight to midnight in military time); the Y axis shows kW (1000 watts). Its max is 0.80 kW or 800 Watts.
B1-Study (dark green) is the power for our living room (my study). It basically shows when I'm there, on the PC. You see it come up to ~200 watts when I powered up around 10:30, around noon it went into standby, etc.
B2-Den (lime) is the wife's PC and the home entertainment system. I probably had lunch and chilled around 2 pm. Later, around 6 pm, the wife turned on her laptop.
B3-KitchenPlus (yellow) covers the kitchen and garage. Notice the refrigerator cycling off and on, and quick peaks when the microwave comes on. It's not shown here, but the oven makes a series of spiky moves hitting 400 W when it comes on... it's actually gas, but has an electrical heating element to help reach temps quick.
B4-MBR+DW (orange) is the master bedroom and dishwasher. Not much happened there that day. We have a lot of little motion night lights, so we don't actually use much energy on that circuit, most of the time. For the record: we have some 20 motion night lights throughout the house; we can walk most anywhere at night without needing to turn on lights. Just like Blade Runner.
B5-Basement (red) shows when stuff is happening there. If you look more closely (can't really see it at this level), the UPS that keeps our internet, Efergy, and a few other electronics periodically sips energy to keep its battery topped.
The inset highlighting ~10:52 pm shows a peak in the kitchen, probably due to the microwave. Our microwave is 1600 watts at the wall if I recall correctly, but because it apparently was on for less than a minute (or was a minute, but started halfway through a minute, like 10:51:30), it doesn't hit 1.6 kW on the graph. Efergy shows average usage for each minute.
I think it's super cool that Efergy is silently, quietly always collecting data on our roaming through the house, and particular activities. It's like a diary of our lives, in motion. In its own little way. This simply wouldn't be possible if you only had one clamp on the mains. It would be very chaotic and the average person would throw up their hands and be content to see big things like their A/Cs. But with 10 streams, we can understand most everything, and see details of our lives.
