Case Study: a US-based global leader in intelligent climate solutions achieves expanded smart home and Siri thermostat controls with Toptal

a US-based global leader in intelligent climate solutions, including heating, cooling, and smart thermostats expands smart home controls with Toptal

The customer, a US-based global leader in intelligent climate solutions, needed additional development expertise to improve its smart home application and introduce more sophisticated thermostat controls. A key challenge was integrating new functionality, which required close coordination with hardware teams and was complicated by device limitations. The company partnered with Toptal for custom software development services to overcome this.

Toptal developers used React Native, GraphQL, Redux, and RTK Query to build advanced features like geofencing and complex scheduling. Crucially, Toptal implemented a custom Siri integration to deliver voice control, working around hardware constraints that prevented conventional Apple HomeKit support. As a result, the application's functionality was significantly expanded and users gained new ways to control their home’s temperature, including through voice commands.
