App & software development

Our open and flexible API makes it easy to bring energy data into your app.

With dozens of successful integrations, our customers tell us they really appreciate our partner-friendly, software-agnostic approach. The simplicity of our API, and our comprehensive documentation, makes integration a breeze. Our scalable and robust infrastructure supports you as your solution grows. And you can use our data services and the My Energy Marketplace datasets to engage customers and validate your solution.


Energy management software-as-a-service group Wattics aims to comprehensively support energy professionals who are designing and delivering efficiency and other upgrade projects. While many energy management software offerings focus on ‘sites’, Wattics’ solution also provides a ‘projects’ perspective.

As Wattics was looking to expand its metering options for markets around the world, they added support for Wattwatchers devices into their product suite. The integration with our API was straightforward, and the cloud-connected combination of Wattics and Wattwatchers has been available internationally since 2019.

Wattics provides a wealth of insight into how meter and sensor data, weather data, IoT, renewable and business data are correlated in industrial and commercial facilities. Its machine-learning technology enables Wattwatchers customers to quickly:

  • identify energy waste;
  • save money;
  • track savings over time;
  • calculate, monitor and report on carbon emissions;
  • and much more.

Energy management is hungry for timely, granular data. One of Wattwatchers longest-established customers, Simble, is an ASX-listed company offering energy intelligence and productivity software solutions.

Operating mainly in Australia and the UK, Simble’s software-as-a-service (SaaS) model works for both commercial and industrial sites (SimbleSense), and residential ones (SimbleHome).

Simble is hardware-agnostic, and Wattwatchers is software-agnostic, allowing non-exclusive partnering that works well for both businesses.
