Chapter 6 - A Look at the Data After the Detected “Lies” are Gone
So I did all that meticulous work for two reasons:
- To pass on my understanding to help others - As I said, I love my Sense, but I really hate it when it gives me easy to detect “bad data”. So I decided to nail down some of the best indicators to help myself and others.
- So I can look more closely at the remaining errors and see if I can identify the original of those.
To reiterate, thanks to the the removal of hours with obvious error indicators and the data from 2019, I have been able to move from this:
To this !
When I look at the linear model and residuals for the remaining data, there are really only 3-10 points outside of what I would regard as the statistical limits of the error distribution, for me to poke into.
If I look at the biggest error/residual hours remaining, all but 3 (circles in green) of the top 10 are explainable due by the installation and playing around with my second Sense.
And the error on 1-20-2021 aligns with me rebooting my Sense because it “lost” a few of my Kasa smartplugs.
