I have four BMExxx/SHT3x/4x sensors outside (in different places) for weather measurement purposes: i measure temperature, humidity and pressure.
Then i created template sensors which takes minimum value for dashboard showing - this way i eliminate, say, sun shining on one of them thus reporting wrong value (this especially goes for temperature).
During the night one of BME’s died on me since it was stuck at same values from 7 morning and it’s unavailable after esp reset. As a result my dashboard was showing wrong values.
Now i wonder - is it possible to create some king of template sensor which takes into account possible “liars”? I was thinking in a way that I’d eliminate any value if it’s outside “decent” range. For example, if 3 sensors show temperature around 9-10 degrees and fourth shows -1 it would be eliminated from “minimum” sensor calculation?
