Enhanced connected bathroom systems with a technology upgrade and
connected mobile application

Client Overview

Australia based innovator and supplier of product solutions, services, and intelligent technology focused on the kitchen and bathroom segments. They also offer smart bathroom systems like IoT smart water management solutions for residential and commercial buildings.

Business Challenge

In sync with the new-age technologies, the client wanted to upgrade their existing solution that would provide the latest connectivity options, quick processing, and a simple architecture with minimum components to maintain. The client was looking for a technology partner who can help them with their current solution upgrade. 

VOLANSYS Contribution

VOLANSYS upgraded the client’s existing microcontroller-based solution to a more robust processor-based VOLANSYS’ Centauri 200 IoT gateway running on Linux OS. This new gateway platform eliminated the concentrator device’s requirement – previously used to manage messages from multiple gateways installed in a building.  It provides the latest connectivity support like BLE 5.0, Wi-Fi, LTE, etc. We also developed an Android and iOS mobile application to commission/service the solution for their system integrators.

  • Firmware design and development
    • Modified BLE manager to accommodate support for CIF1 protocol, bathroom devices, communication between devices, and daily data synchronization 
    • Developed the cloud manager with a secure connection to cloud to support Gateway configuration, device monitoring, and control
    • Developed a BACnet/IP client manager to support the commands on BACnet/IP protocol
    • Documented steps to update the network properties, registering BLE fixture devices using local editors and command-line tools
    • Support for secure boot with VOLANSYS’ Centauri 200 gateway
    • Added support for HTTP web server to support communication with commissioning application
    • Designed and developed OTA manager to support communication with cloud
    • Added support for dockerized container for application with security using container secrets
  • Mobile application
    • Designed UI-UX wireframes for the device and gateway commissioning application
    • Developed a mobile application library that supports the functionality of secure access, commissioning of BLE devices, gateway, and Wi-Fi provisioning
    • Published application to App Store and Google Play Store
  • Quality Engineering
    • Created test plan and test cases for all the functionalities of the gateway
    • End-to-end system integration and testing
    • Supported the client’s team during their field trials and quickly resolved the bugs reported by generating the same locally
    • Integrate the gateway with automated BAC net regression testing tool, (BOTS) for protocol testing and reliability testing
    • Gateway health monitoring and housekeeping
