I bought this to measure how much electricity is consumed while charging Tesla. What this device does is give you that info for Today. then AVG for 7 days and AVG for 30 days. I don't need AVG it is useless to me. Because if I start charging my car at 7 pm next day I do not know how much it consumed 7pm -12am. Either give me a second screen where it just show All Time Consumption or give me an opportunity to see what Consumption by day at least for the past week. I do not need averages . Averages may be good where there is non stop consumption. But devices that are plugged occasionally but consume a lot - this Kasa plug is useless.
