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. ////////////////////////////////////// struct PressureSensor : Service::AtmosphericPressureSensor { // A standalone Air Pressure Sensor Characteristic::AtmosphericPressure pressure; // Eve Air Pressure with range 700-1200 hPa (millibars), where 1 atm=1013 hPa PressureSensor() : Service::AtmosphericPressureSensor{} { Serial.print("Configuring Air Pressure Sensor"); // initialization message Serial.print("\n"); } // end constructor void loop(){ if(pressure.timeVal()>5000) // here we simulate an actual sensor by generating a random pressure reading every 5 seconds pressure.setVal((double)random(900,1100)); } // end loop }; // end PressureSensor ////////////////////////////////////// void setup() { Serial.begin(115200); homeSpan.begin(Category::Sensors,"Eve Air Pressure"); SPAN_ACCESSORY(); new PressureSensor(); } ////////////////////////////////////// void loop(){ homeSpan.poll(); }
