in detail

Leobit collaborates closely with the client’s embedded team to develop an IoT mobile app that seamlessly integrates with hardware components.

Our development team has built a comprehensive smart home app by harnessing a potential of the Flutter framework to deliver a consistent and ideal user experience, regardless of their preferred device, improving overall usability and convenience.

The system’s central component is the highly capable smart home hub. The hub takes charge of establishing communication with various smart IoT devices including smoke detectors, thermostats, light systems, water protection systems, and smart door locks. Through the app, users have the ability to manage various tasks, while a central hub ensures that all devices stay connected. The IoT devices within the home then carry out the user’s commands effectively, making the whole system work smoothly.

The app’s functionality for creating and managing homes and rooms is designed to provide users with a structured approach to organizing their smart devices within their living spaces. When users access the app, they are given the choice to either create a new “home” or join an existing one. Once a choice is made, users are directed to the designated information page specific to the selected home.

This page comprises several fields of home-specific information that should be filled out. In order to streamline effective management of their smart devices, the app equips users with the ability to establish rooms within their homes. This feature make it easier to track and oversight of individual devices, fostering a more organized management experience.

The functionality for managing home members within the app operates through a series of steps, designed to streamline the process of managing individuals associated with a residence. Users can input contact information manually or opt to retrieve it from their mobile phone’s contact list. This integration simplifies the data input process. Upon gathering the necessary contact information, users can then initiate the inclusion of home members by utilizing various communication channels. This includes sending invitations through email or SMS.

Additionally, a QR code generation feature is available, allowing for an innovative approach to inviting new home members. Each home member can be linked to multiple residences. Moreover, this functionality isn’t solely limited to internal household members; it also extends to external stakeholders. These stakeholders encompass housing associations, installation professionals, and in-home delivery personnel. To uphold robust security measures, the system incorporates diverse role-based access controls, each associated with specific access restrictions tailored to designated functionalities.

For home security functionality, we integrated multiple smart lock systems into the app ecosystem. The process encompasses establishing secure communication protocols to enable real-time monitoring of the lock’s status within the app interface. Users are now granted not only a comprehensive overview of the lock’s security status, but also the advanced capability to remotely unlock the doors for specific reasons.

Water Leak Detection

The system operates using strategically placed water leak sensors equipped with advanced technology to precisely monitor water flow rates. These sensors, supported by sophisticated algorithms, promptly detect anomalies indicating potential leaks. The collaboration with Waterguard, a Norwegian water leak detection provider, enhances the system's effectiveness.

When a water leak sensor triggers the valve control, real-time alerts are sent through the app to homeowners' mobile devices for immediate response. By accessing the app's interface, users can swiftly trigger the shutdown of the water supply to prevent any further damage.


Smart Light Control

The implementation of the smart light control functionality within the app serves as a user-centric solution for effortless activation/deactivation of home lightingand electrical devices.

The app's compatibility with renowned brands, like Philips Hue and IKEA Home, further guarantees a better experience for users who have smart lighting solutions from these manufacturers.


Energy Consumption Monitoring

The app grants users access to an exclusive electricity management tool. Through the app, users gain a clear and independent view of their home's power usage, regardless of their electricity provider. This feature gives users more control over their consumption, enabling them to track trends, view historical data, and compare costs between different months and years.

The app is seamlessly connected to Nordpool, Europe's leading electricity stock market, fetching hourly prices. For a more detailed view, users can also link the app to Elhub, a central system in Norway that manages and measures power consumption across the country.

This integration enhances the app's capabilities, giving users a comprehensive understanding of their power usage and cost calculations based on real-time pricing data.


Fire Alarm Notification

The technical foundation is rooted in wireless communication, specifically employing the Zigbee protocol. This allows smoke detectors to communicate seamlessly with each other and with the app. In case any device detects smoke, this triggers an alarm. The app ensures all home members are promptly notified via their mobile devices.

This is achieved through a combination of SMS and push notifications, leveraging the app's connectivity to send urgent alerts directly to users' smartphones. The app's functionality further extends to establishing a secure connection with a designated 24/7 alarm station. This integration involves the establishment of secure communication channels and protocols to swiftly transmit emergency notification, GPS coordinates, and user information to the designated fire station.
