Closeup of my Efergy hubs, with one of them plugged into that Ensupra energy monitor.

The hub lights don't show well here, but the left (red) power light and right (green) LAN light are always on, and the yellow light in the middle flickers as it gets a brief signal. In theory it flickers 5 times every 10 seconds but I'd need to video capture to say exactly how long... surely less than 20% of the time.

The Ensupra monitor has one of the hubs' adapter connected. You can see that the Efergy hub adapters are rated for 0.5 V x 0.3 A = 1.5 W (DC), but in fact only use 1.1 W. Actually it sometimes does 1.2, so maybe it's more like 1.13 W.

Please ignore the 1714 kWh reading on the Ensupra monitor. I did not bother to reset its totals after yanking it off of a high-throughput dehumidifer.

They're sitting on top of a simple LAN switch into which the two hubs and three other things plug in (SmartThings hub, secondary house wifi router, and a bedroom's local switch). All these and some other electronics are working off of the CyberPower 1500AV UPS. Even if power goes down, everything stays connected... the internet connection does not go down, because all the internet gear is on this UPS. Sadly, it goes down fairly frequently here - a couple of dropouts for only a few seconds or a minute each month. Just enough to make everything reboot if it's not on UPS. Grr on Georgia Power.

Because we use Google Fi for our cellphones, even our phones (and internet browsing through them) does not go down, if power goes down, so long as the UPS is still up. (Good luck following all that.) Yes, we have found that our upstream Charter/Spectrum internet does not go down when power goes out in the neighborhood; it never has to date. So it must have its own UPSs.

It is very cool to see Efergy graphs all go to zero, but without any discontinuity in their graphs, as used to happen before I got all our internet infrastructure on the UPS. With the UPS powering my Efergy and internet, I now even see dips to zero power. Thank you, technology.
