I had another device detected and found what it was right away.
It’s a space heater in my garage and so I did some looking close
at the device page because I haven’t been trusting usage data.
Here is what I found:
The pictures are out of order but they were taken back to back
right at 1:10 a.m.
The deice page shows the heater is on and using 1527 watts, it’s
been on for 27 minutes 12 seconds.
So that means it’s been on since around 12:43 so 17 minutes between
12 and 1.
Now look at the next picture which is after I scrolled down and highlighted
the green bar for the 12 to 1 hour and the total on time in the lower right.
How do I have .4 KWH usage in 1 minute 55 seconds? Impossible
The .4 is really close for 17 minutes use but not 2 minutes
