homebridge-functor
Sometimes you just want to connect something simple to HomeKit (or Alexa). homebridge-functor allows you to do this with "middleware-like" configuration. You just list out your devices, point them to the functions that implement getter/setters for the properties, and you're done. The library is Promise-aware, so you can use fancy ES7 async/await to make it look better.
// mySwitch.js
export async function getPower(device) {
await Promise.delay(1); // This is just a simulation
console.log(`getPower called for ${device.name}`);
return true;
}
export async function setPower(device, value) {
await Promise.delay(1);
console.log(`setPower ${value} called for ${device.name}`);
return;
}
And the corresponding portion of HomeKit config.json
{
"platform": "Functor",
"devices": [{
"name": "Fake Switch",
"serial": "12345678",
"module": "func:./mySwitch.js"
}, {
"name": "Other Fake Switch",
"serial": "212345678",
"getPower": "func:./mySwitch.js#getPower",
"setPower": "func:./mySwitch.js#setPower"
}]
}
Now you can say "Hey Siri, turn the fake switch on." The two devices above are just two ways of expressing the same thing; the first being a monolithic module that implements all the events, the second being one function at a time. You can also specify event handlers (only the onCreate event exists so far).
