enhancing tankless water heaters with a
scalable mobile app and a robust
AWS cloud application

customer background

This customer is the world’s leading producer of water heating solutions, ranging from gas and kitchen appliances to heating and air conditioning (HVAC) units. With over a century of expertise, our customer is dedicated to sustainability and creating a higher standard of living through their cutting-edge solutions.

customer need

The customer had two mobile apps: one for homeowners to monitor/control appliances and another for industry professionals for device configuration and access to user manuals. However, these apps and their cloud application faced multiple performance, stability, and scalability issues. To improve the user experience for both end users and industry professionals, the customer planned to merge both apps. With 20+ years of experience in building automation and over a decade in developing digital controls solutions for water heaters (residential and commercial) and boilers, Softdel was the clear choice for the collaboration. Leveraging its expertise in creating BLE and Wi-Fi-based mobile apps, Softdel revamped the app front end with intuitive UI/UX and enhanced the existing AWS cloud backend to accommodate these changes.
