+// Apple's HomeKit does not provide any native services or characteristics for measuring atmospheric pressure.
+// However, Eve for HomeKit does support pressure measurements.
+
+// This brief sketch demonstrates how you can use HomeSpan's Custom Service and Custom Characteristic features
+// to create a Pressure Sensor Accessory that will be recognized by the Eve for HomeKit App. Note that the
+// Apple Home App will show this as a "Not Supported" Accessory Tile indicating it cannot be used in the Home App.
+// However, this does not create any problems or errors in the Home App.
+
+// Step 1:
+
+//    Use the CUSTOM_SERV macro to create a new service named AtmosphericPressureSensor with
+//    a UUID=E863F00A-079E-48FF-8F27-9C2605A29F52. This new service will be added to HomeSpan's Service namespace
+//    and can be accessed using the fully-qualified name Service::AtmosphericPressureSensor.  The UUID specified
+//    will not be recognized by Apple's Home App, but will be recognized by the Eve for HomeKit App. Note you
+//    do NOT enclose either of the parameters in quotes!
+
+  CUSTOM_SERV(AtmosphericPressureSensor, E863F00A-079E-48FF-8F27-9C2605A29F52);
+
+// Step 2:
+
+//    Use the CUSTOM_CHAR macro to create a new characteristic named AtmosphericPressure with
+//    a UUID=E863F10F-079E-48FF-8F27-9C2605A29F52. This new characteristic will be added to HomeSpan's Characteristic namespace
+//    and can be accessed using the fully-qualified name Characteristic::AtmosphericPressure.  The UUID specified will not be
+//    recognized by Apple's Home App, but will be recognized by the Eve for HomeKit App. Note you do NOT enclose any of the
+//    parameters in quotes!
+//
+//    The meaning of the parmameters are as follows:
+//
+//      PR+EV:    sets permission for "read" and "notify"
+//      FLOAT:    sets the format to floating-point decimal number
+//      1013:     sets the default starting value to 1013, which is 1 atm in millibars
+//      700:      sets the default lower range of allowed values to 700 millibars
+//      1200:     sets the default upper range of allowed values to 1200 millibars
+//      false:    sets the "static range" flag to false, indicating that users CAN override the default range setRange() if desired
+
+  CUSTOM_CHAR(AtmosphericPressure, E863F10F-079E-48FF-8F27-9C2605A29F52, PR+EV, FLOAT, 1013, 700, 1200, false);
+
+// Now that AtmosphericPressureSensor and AtmosphericPressure have been created, they can be used just as any other native HomeSpan
+// Service and Characteristic.
