Interpret measurement status bars
A "Good" or "Bad" status next to a value is an indication of the reliability or integrity of the data being
received, not an indication of whether or not the value is within the configured upper or lower ranges. A
value that triggers an alert, such as a high or low temperature indication, will change the overall status of
the device, but the measurement might still be indicated as "Good" if the reliability of the data is good.
