Though the interface does not say, I assume these two columns are for each leg of the power mains. What you see here is typical for my usage. Lots of load on the one leg and very little on the other. I can only assume this is a bad thing. Does this have any bearing on device detection? I got the fridge, microwave and some of the heater in the first few days. Now it’s been several days since any new device was detected.
