An Intro to the Hack-the-House tech

1. Hack The House
Technical Briefing

2. Hacking for the
Internet of Things

3. 3 simple rules
1. Delays are to be expected
a. Non-blocking asynchronous code
b. Work with mocks
c. let the user know you are working (spinners, etc)
2. Study the APIs & SDKs
3. Start small and add features - MVP thinking
a. Do the Hard stuff first
b. Have fun (at the end)

4. Devices at the Hackathon

14. OnBoarding your BSH Device

22. relayr SDKs and API

23. HTML5 library initialize
//Initialize the Relayr SDK, you must give a RedirectURI and AppID
var relayr = RELAYR.init({
appId: "b616cb5d-17e6-4f57-aec5-e6eb1ab3de29",
});

24. HTML5 library Get Data
//If you have a token and your device ID, you can start listening to your
device without going through the login process
relayr.devices().getDeviceData({
token: "p7xjSVAhqP9gtqvg9aGD_dZ4DDzlSJHw",
deviceId:"c9b48194-bd71-42a6-9c11-f6901b9c9017",
incomingData: function(data){
console.log("data from single sensor with specific token", data);
}
});

25. HTML5 library Send Commands
//Turn you're BSH oven on
relayr.devices().sendCommand({
//you're relayr token if you haven't included it before
token: "p7xjSVAhqP9gtqvg9aGD_dZ4DDzlSJHw",
//relayr ID of you're oven
deviceId:"c9b48194-bd71-42a6-9c11-f6901b9c9017",
//turns on the Oven
command:{"path":"power_unit", "command": "power", "value": 2}
});

26. Android SDK
// INITIALIZE
private void loadUserInfo() {
RelayrSdk.getRelayrApi()
.getUserInfo()
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.subscribe(new Subscriber<User>() {
//...
@Override
public void onNext(User user) {
loadDevices(user.id);
}
});
}

27. // LOAD DEVICES
private void loadDevices(String userId) {
RelayrSdk.getRelayrApi()
.getTransmitters(userId)
.flatMap(new Func1<List<Transmitter>, Observable<List<TransmitterDevice>>>() {
@Override
public Observable<List<TransmitterDevice>> call(List<Transmitter> transmitters)
{
return
RelayrSdk.getRelayrApi().getTransmitterDevices(transmitters.get(0).id);
}
})
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.subscribe(new Subscriber<List<TransmitterDevice>>() {
//...
@Override
public void onNext(List<TransmitterDevice> devices) {
if (!devices.isEmpty())
subscribeForUpdates(devices.get(0));
}
});
}

28. // HANDLE DATA
private void subscribeForUpdates(TransmitterDevice transmitterDevice) {
RelayrSdk.getWebSocketClient()
.subscribe(transmitterDevice)
.observeOn(AndroidSchedulers.mainThread())
.subscribe(new Observer<Object>() {
@Override
public void onCompleted() {
}
@Override
public void onError(Throwable e) {
e.printStackTrace();
}
@Override
public void onNext(Object o) {
//Parse data depending on device model
Log.i("DATA", o.toString());
}
});
}

29. // Send a Command
int value = 2;
String path = "power_unit";
String command = "power";
Command mCommand = new Command(path, command, value);
RelayrSdk.getRelayrApi()
.sendCommand(deviceId, mCommand)
.observeOn(AndroidSchedulers.mainThread())
.subscribe(new Observer<Void>() {
@Override
public void onCompleted() {
}
@Override
public void onError(Throwable e) {
e.printStackTrace();
}
@Override
public void onNext(Void aVoid) {
Log.i("TAG", "Command sent");
}
});
