+Methods                void MeasureReceived(dict measure)

typo (measure vs. measurement)

+
+                       This callback gets called when a measure has been
+                       scanned in the thermometer. The Time entry in the dict
+                       will be only present if the device supports storing of
+                       data. The time value is expressed in seconds since epoch.
+                       The value represented is (mantissa) x (10**exponent)
+                       See foot note for special values when treating with
+                       health devices.

IIRC, the "Type" value is also optional.

+
+                       Dict is defined as below:
+                       {
+                               "Exponent" : int8,
+                               "Mantissa" : int32,
+                               "Unit" : ("Celsius" or "Fahrenheit"),
+                               "Time" : uint64,
+                               "Type" : ("Armpit", "Body", "Ear", "Finger",
+                                       "Intestines", "Mouth", "Rectum", "Toe",
+                                       "Tympanum"),
+                               "Measurement" : ("Final" or "Intermediate"),
+                       }
+
+                       For special cases, the exponent shall always be zero and
+                       the mantissa should be one of following values:
+
+                       NRes = -(2**23)
+                       NaN = +(2**23-1)
+                       INFINITY = (2**23-2)
+                       -INFINITY = -(2**23-2)
