About us

SMART HOME LIVE

MOTIVATION

1

• Demo system objectives• Fire dangers• Improving existing

solutions

OVERVIEW

2

• 1st live demo –smoke detector features

• Basic architecture

SETUP

3

• Architectural details• 2nd live demo –

smart home integration

CONCLUSION

4

• Lessons learned• Outlook

Evaluate available technologies like MQTT, Eclipse SmartHome

We are not building a product! We are building a live demo so that people can experience smart home use cases

Iterate and explore key features for an intelligent smart home

Why are we doing this?

“How can the insurance industry play an active role in the area of security at home”

Fires are life threatening dangerous

400 deaths 4000 injured

200.000

€1 billion

3 breaths can be sufficient to die

1 breath can have lifelong consequences

“Where there's fire there's smoke”

of fires start at night where

human‘s sense of smell is asleep70 %

Fire! Time to leave!

SMOKE DETECTORS are mandatory

In Germany2018

In France2015

In USA2010

Now some code!!

MQTT Publish

MqttClient mqttClient = new MqttClient

("tcp://localhost:1883", “publisher");

mqttClient.connect();

mqttClient.publish(“test","test123".getBytes(),0, true);

MQTT Subscribe

MqttCallback mqttCallback = new MqttCallback() {

@Override

public void messageArrived(String topic, MqttMessage mqttMessage)

{

System.out.println(topic +" "+ new String(mqttMessage.getPayload()));

}

};

MqttClient mqttClient = new MqttClient("tcp://localhost:1883", “subscriber");

mqttClient.setCallback(mqttCallback);

mqttClient.connect();

mqttClient.subscribe(“test",2);
