OK, the stock timing / sampling is very quick. You’ll see that if you touch the BME280. You get a nice quick response and it looks cool. Thing is, after a second or two the readings will stabilize, and the graph will be a straight line. When that happens you get just the one color. All the plots are almost the same reading. Normal temperature change won’t be fast enough to be seen as a color change. It wasn’t for me anyway, that’s why I played around with the sampling rate. That got me this.
