I noticed that one of my devices has an off color shade. I’m using the blue theme so most circles are blue, but the circle for my dehumidifier is purple. I noticed others who have posted screenshots sometimes have an off shade orange circle, since they’re using the orange theme. Thoughts on the meaning?
No meaning at all! Bubbles will populate with different shades just to allow for easier reading.
I want to suggest that your dehumidifier has sprung a leak. It’s the water…
(You needed that!)
