void setup() {
// Every Accessory we define has at least two Services, one of which will always be the required Accessory Information Service (and
// which we've conveniently wrapped into a derived Service we called DEV_Identify). The second is usually a Service that performs
// some sort of actual operation, such as the LightBulb Service or the Fan Service. It's this second operative Service that creates
// the controls we see in the HomeKit iOS or MacOS application. These appear as tiles with a lightbulb control or fan control.
// We've also created Accessories with more than two operational Service, such as our definition of a ceiling fan that includes
// BOTH a Fan Service and a LightBulb Service. The HomeKit application can display an Accessory with two or more operational Services
// in one of two ways: one way is to display each Service as a separate tile, so that our ceiling fan would show up as one standalone
// lightbulb tile for the LightBulb Service and one standalone fan tile for the Fan Service. The second way is for HomeKit to display
// our ceiling fan as a single tile that you click to open a new screen showing both the fan control and the lightbulb control side by side.
// HomeSpan has no control over whether HomeKit displays multiple Services as separate tiles or as a single combined single tile.
// This is determined by the user from within the HomeKit iOS or MacOS application (the default is to use the combined tile mode).
// However, HomeSpan does have control over the which icon is used to display the ceiling fan in combined-tile mode. Should it be a
// lightbulb or a fan?
// HomeKit determines which icon to show on the combined tile according to what is considered the Primary Service of the Accessory.
// HomeKit will also list the Primary Service first when you click a combined tile to open its controls.
// A Service can be set to Primary with the setPrimary() method. The easiest way to do this is by "chaining" setPrimary() to the
// end of a new Service when first instantiated. See below for examples of how to do this.
// To begin, we first initialize HomeSpan and define our Bridge Accessory as in the previous examples:
Serial.begin(115200);
homeSpan.begin(Category::Bridges,"HomeSpan Bridge");
new SpanAccessory();
new DEV_Identify("Bridge #1","HomeSpan","123-ABC","HS Bridge","0.9",3);
new Service::HAPProtocolInformation();
new Characteristic::Version("1.1.0");
// Next, we create two Accessories each configured to control a Ceiling Fan containing a bi-directional, multi-speed fan AND a dimmable light.
// In Ceiling Fan #1 we specify the Dimmable LED as the Primary Service. In Ceiling Fan #2 we specify the Fan as the Primary Service.
// If you set HomeKit to display each of these Accessories as combined tiles, you'll immediately see the difference. Ceiling Fan #1 shows as
// Lightbulb Tile with the dimmable LED listed first when you click open its controls. Ceiling Fan #2 shows as a Fan Tile with the fan listed first
// when you click open its controls. Nice and easy.
new SpanAccessory();
new DEV_Identify("Ceiling Fan #1","HomeSpan","123-ABC","20mA LED","0.9",0);
(new DEV_DimmableLED(17))->setPrimary(); // Here we specify DEV_DimmableLED as the Primary Service by "chaining" setPrimary() to the pointer return by new. Note parentheses!
new Service::Fan();
new Characteristic::Active();
new Characteristic::RotationDirection();
new Characteristic::RotationSpeed(0);
new SpanAccessory();
new DEV_Identify("Ceiling Fan #2","HomeSpan","123-ABC","20mA LED","0.9",0);
new DEV_DimmableLED(17);
(new Service::Fan())->setPrimary(); // Here we specify the Fan as the Primary Service. Again, note how we encapsulated the "new" command in parentheses, then chained setPrimary()
new Characteristic::Active();
new Characteristic::RotationDirection();
new Characteristic::RotationSpeed(0);
//////////////////////////////////
// In addition to being able to specify which Service in an Accessory is the Primary Service, HomeKit also allows you to give names to each of
// the individual Services. This is done by instantiating a Name Characteristic for a Service. We've already used this feature in creating
// DEV_Identify --- the first argument is used to to name the Service (see DEV_Identify.h). In fact, the Name Characteristic is required
// for the AccessoryInformation Service, so we had to instantiate as part of DEV_Identify.
// For all other Services the name Characteristic is optional. If not instantiated, the name will be defaulted to whatever name we specified
// in DEV_Identify, which means that if we have more than one operational Service in an Accessory, they will all be named the same.
// This is not necessarily a problem since names don't always come into play in the HomeKit interface. In the examples above, the only name
// that gets displayed in combined-tile mode is "Ceiling Fan #1" or "Ceiling Fan #2", which makes sense. When you click open the controls
// for either Accessory you see a lightbulb control and a fan control. They are not individually named, but the controls look different (one
// is a light control, the other a fan control) so there is no confusion.
// If instead you set HomeKit to display the controls for these Accessories as separate tiles, you'll see that each of the light and fan controls
// has their own name. But since in the above examples we did not provide specific names for each of these Services, they will simply inherit the
// name "Ceiling Fan #1" or "Ceiling Fan #2". Again, there is no confusion since the light and fan controls each look different.
// The situation becomes more interesting when you have an Accessory with 3 or more operational Services. Sometimes HomeKit will display the names
// of the Services on the control panel even in combined-tile mode. Consider our ceiling fan example above, but with the added feature of a night-light,
// which we will represent as a simple On/Off LED. Let's instantiate the Name Characteristic for each Service, as shown below.
new SpanAccessory();
new DEV_Identify("Ceiling Fan #3","HomeSpan","123-ABC","20mA LED","0.9",0);
new DEV_DimmableLED(17);
new Characteristic::Name("Main Light"); // Here we create a name for the Dimmable LED
new DEV_LED(16);
new Characteristic::Name("Night Light"); // Here we create a name for the On/Off LED
(new Service::Fan())->setPrimary();
new Characteristic::Active();
new Characteristic::RotationDirection();
new Characteristic::RotationSpeed(0);
new Characteristic::Name("Fan"); // Here we create a name for the Fan
// If you let HomeKit display this as a single, combined tile, you'll notice two things. The first is that the name of the tile is now "Fan" instead
// of "Ceiling Fan #3". Why is that? It's because we set Fan to be the Primary Service AND gave it a name --- this is the name that shows up
// on the combined tile. If we did not give it a name, it would have inherited the name "Ceiling Fan #3", which would have been the name of the tile
// as in the prior example.
// The second thing you'll notice is that these names now appear next to each control if you click open the combined tile. It says "Fan" next to the Fan
// control, "Main Light" next to the Dimmable LED control, and "Night Light" next to the On/Off LED control.
// If instead you tell HomeKit to display the controls for Ceiling Fan #3 as three separate tiles, you'll see that each tile contains the name specified
// above for that Service. In some circumstances that can be helpful, in others it can be confusing. For instance, if you had two ceiling fans that
// each had a main light and a night night, how would you know which "Main Light" is which? One solution is to create names like "Main Light #3" and
// "Main Light #4". The other solution is to keep them combined in a single tile, but keep the name "Ceiling Fan #3" for the combined tile, instead of
// having it over-ridden with the word "Fan"
// This is easily done by specifying DEV_Identify as the Primary Service, instead of Fan, as follows:
new SpanAccessory();
(new DEV_Identify("Ceiling Fan #4","HomeSpan","123-ABC","20mA LED","0.9",0))->setPrimary(); // specify DEV_Identify as the Primary Service
new DEV_DimmableLED(17);
new Characteristic::Name("Main Light");
new DEV_LED(16);
new Characteristic::Name("Night Light");
new Service::Fan();
new Characteristic::Active();
new Characteristic::RotationDirection();
new Characteristic::RotationSpeed(0);
new Characteristic::Name("Fan");
// HomeKit now shows the name "Ceiling Fan #4" for the combined tile AND it still shows the individual names for each control when you click open the tile.
// The only downside to this configuration is that since the Fan is no longer specified as the Primary Service, the main icon on the combined tile now shows
// as a lightbulb, instead of the fan. HomeKit documentation is not clear on how the main icon is chosen under these circumstances, but I've found
// that changing the order of Services as they are instantiated can impact the icon. Here is the same example as above, but with the Fan
// instantiated as the first operational Service, ahead of the Main Light and Night Night:
new SpanAccessory();
(new DEV_Identify("Ceiling Fan #5","HomeSpan","123-ABC","20mA LED","0.9",0))->setPrimary(); // specify DEV_Identify as the Primary Service
new Service::Fan();
new Characteristic::Active();
new Characteristic::RotationDirection();
new Characteristic::RotationSpeed(0);
new Characteristic::Name("Fan");
new DEV_DimmableLED(17);
new Characteristic::Name("Main Light");
new DEV_LED(16);
new Characteristic::Name("Night Light");
// This seems to cause HomeKit to display the Fan icon on the combined tile, as well as to list the Fan Service control first when the tile is clicked
// open, almost as if it were the Primary Service in all ways except for its name.
// As you can see, there is no right or wrong way for how to name your Accessories and Services, including whether or not to even bother naming your
// individual Services. It's purely a matter of taste - experiment and see which combinations best serve your purposes.
// IMPORTANT: HomeKit tries to cache as many items as possible, and although it should know when configurations change, it does not always respond
// as expected. If you are experimenting and find that name changes are NOT being reflected in the HomeKit interface, simply unpair HomeSpan and
// re-pair. This often causes a refresh. If not, after unpairing you can additionally reset the HAP data in HomeSpan so that its HAP ID changes (see
// HomeSpan documentation for how to easily do this). This way when you re-pair, HomeKit should think this is a completely new device and start with
// a clean slate. *** In some limited circumstances, HomeKit may get so confused it refuses to operate the Accessories at all. You may get a No Response
// icon even though HomeSpan is operating correctly. Though it is possible to misconfigure HomeSpan in ways that cause this, if you do get this
// error please try the re-pairing methods above as it often fixes the problem.
