|
|
new Characteristic::On(true); // NEW: Providing an argument sets its initial value. In this case it means the LightBulb will be turned on at start-up
|
||
|
|
|
||
|
|
// In addition to setting the initial value of a Characteristic, it is also possible to override the default min/max/step range specified by HAP.
|
||
|
|
// We do this with the setRange() method:
|
||
|
|
|
||
|
|
// setRange(min, max, step), where
|
||
|
|
//
|
||
|
|
// min = minimum allowed value
|
||
|
|
// max = maximum allowed value
|
||
|
|
// step = step size (can be left blank, in which case the HAP default is retained)
|
||
|
|
|
||
|
|
// The setRange() method can be called on any numerical-based Characteristic that supports range overrides. The easiest way to apply to method is to call it right
|
||
|
|
// after instantiating a new Characteristic. Don't forget to surround the "new" command in parentheses when chaining a method in this fashion.
|
||
|
|
|
||
|
|
// Here we create a Brightness Characteristic to set the brightness of the LightBulb with an initial value of 50% and an allowable range
|
||
|
|
// from 20-100% in steps of 5%. See Notes 1 and 2 below for more details:
|
||
|
|
|
||
|
|
(new Characteristic::Brightness(50))->setRange(20,100,5);
|
||
|
|
|
||
|
|
new Service::Fan();
|
||
|
|
new Characteristic::Active();
|
||
|
|
new Characteristic::RotationDirection(); // NEW: This allows control of the Rotation Direction of the Fan
|
||
|
|
(new Characteristic::RotationSpeed(50))->setRange(0,100,25); // NEW: This allows control of the Rotation Speed of the Fan, with an initial value of 50% and a range from 0-100 in steps of 25%
|
||
|
|
|
||
|
|
// NOTE 1: Setting the initial value of the Brightness Characteristic to 50% does not by itself cause HomeKit to turn the light on to 50% upon start-up.
|
||
|
|
// Rather, this is governed by the initial value of the On Characteristic, which in this case happens to be set to true. If it were set to false,
|
||
|
|
// or left unspecified (default is false) then the LightBulb will be off at start-up. However, it will jump to 50% brightness as soon as turned on
|
||
|
|
// for the first time. This same logic applies to the Active and RotationSpeed Characteristics for a Fan.
|
||
|
|
|
||
|
|
// NOTE 2: The default range for Characteristics that support a range of values is specified in HAP Section 9. For Brightness, the range defaults
|
||
|
|
// to min=0%, max=100%, step=1%. Using setRange() to change the minimum Brightness from 0% to 20% (or any non-zero value) provides for a better
|
||
|
|
// HomeKit experience. This is because the LightBulb power is controlled by the On Characteristic, and allowing Brightness to be as low as 0%
|
||
|
|
// sometimes results in HomeKit turning on the LightBulb but with Brightness=0%, which is not very intuitive. This can occur when asking Siri
|
||
|
|
// to lower the Brightness all the way, and then turning on the LightBulb. By setting a minumum value of 20%, HomeKit always ensures that there is
|
||
|
|
// some Brightness value whenever the LightBulb is turned on.
