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.
