+Health Thermometer Profile hierarchy
+=====================================
+
+Service		org.bluez
+Interface	org.bluez.Thermometer
+Object path	[variable prefix]/{hci0,hci1,...}/dev_XX_XX_XX_XX_XX_XX
+
+
+Methods		void SetProperty(string name, variant value)
+
+			Changes the value of the specified property. Only
+			read-write properties can be changed. On success
+			this will emit a PropertyChanged signal.
+
+			Possible Errors: org.bluez.Error.InvalidArguments
+
+		dict GetProperties()
+
+			Returns all properties for the interface. See the
+			Properties section for the available properties.
+
+		RegisterWatcher(object agent)
+
+			Registers a watcher to monitor scanned measurements.
+			This agent will be notified about final temperature
+			measurements.
+
+			Possible Errors: org.bluez.Error.InvalidArguments
+
+		UnregisterWatcher(object agent)
+
+			Unregisters a watcher.
+
+			Final and intermediate temperatures won't be notified to
+			this agent any more.
+
+			Possible Errors: org.bluez.Error.InvalidArguments
+					org.bluez.Error.NotFound
+
+		EnableIntermediateMeasurement(object agent)
+
+			Enables intermediate measurement notifications for this
+			agent if the thermometer supports it.
+
+			Possible Errors: org.bluez.Error.InvalidArguments
+					org.bluez.Error.NotSupported
+
+		DisableIntermediateMeasurement(object agent)
+
+			Disables intermediate measurement notifications for this
+			agent. It will disable notifications in the thermometer
+			when the last agent removes the watcher for intermediate
+			measurements.
+
+			Possible Errors: org.bluez.Error.InvalidArguments
+					org.bluez.Error.NotFound
+
+Signals		PropertyChanged(string name, variant value)
+
+			This signal indicates a changed value of the given
+			property.
+
+Properties	boolean Intermediate [readonly]
+
+			True if the thermometer supports intermediate measurement
+			notifications.
+
+		uint16 Interval (optional) [readwrite]
+
+			The Measurement Interval defines the time (in seconds)
+			between measurements. This interval is not related to
+			the intermediate measurements and must be defined into
+			a valid range. Setting it to zero means that no periodic
+			measurements will be taken.
+
+		uint16 Maximum (optional) [readonly]
+
+			Defines the maximum value allowed for the interval
+			between periodic measurements.
+
+		uint16 Minimum (optional) [readonly]
+
+			Defines the minimum value allowed for the interval
+			between periodic measurements.
+
+
+Health Thermometer Watcher hierarchy
+====================================
+Service		unique name
+Interface	org.bluez.ThermometerWatcher
+Object path	freely definable
+
+Methods		void MeasurementReceived(dict measure)
+
+			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.
+
+			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)
