My temperature/humidity sensors that are outdoors do not show temps over 99 on the charts. In the device listing they show the temps accurately (up to 120 so far)! In the settings I do not specify a maximum, leaving it blank for "auto". How can I fix this?
I have several graphs that report temps above 100, So my guess is you have a max set for your left axis. Should be set on configure graphs.
As I said, "I do not specify a maximum, leaving it blank for "auto". My configuration looks just like your image, saying "Click to set". I like it auto so that the top line adjusts to the highest reading normally.
Not sure what to tell you. Below is a screenshot from the sensor in my attic. The temp goes well above 100. So I would look real close and see if you are missing something, because I have never seen this issue. Perhaps @nh.schottfam has an idea.
