Energy wastage by residential buildings is a significant contributor to total worldwide energy consumption. Quby, an Amsterdam based technology company, offers solutions to empower homeowners to stay in control of their electricity, gas and water usage. Using Europe's largest energy dataset, consisting of petabytes of IoT data, the company has developed AI-powered products that are used by hundreds of thousands of users daily to maintain a comfortable climate in their homes and reduce their environmental footprint. In this talk, Erni and Stephen will take you on a tour of how Quby leverages the full Databricks stack to quickly prototype, validate, launch and scale data science products. We will explore the technical workflow of a Data Science project from end to end. Starting from developing a notebook prototype and tracking model performance with MLflow, we move towards production-grade Databricks jobs with a CI/CD pipeline and monitoring system in place. We will see how Quby manages more than 1 million models in production, how Delta Lake allows batch and streaming on the same IoT data and the impact these tools have had on the team itself.

Quby is the creator and provider of Toon, a leading European smart home platform. We enable Toon users to control and monitor their homes using both an in-home display and app. As a data driven company, we use AI and machine learning to generate actionable insights for our end users. Using the data we collect via our IoT devices we have introduced multiple data driven services, including an energy waste checker and a boiler monitoring service. In this talk, Stephen will describe how AI and machine learning are implemented on the Toon platform, and will show multiple AI use cases relating to the connected home. We'll take a look at how Deep Learning algorithms are used to detect inefficient appliances from electricity meter data and how streaming algorithms allow users to be alerted to anomalies with their heating systems in near real-time. Stephen will share the experiences from the Data Science and Data Engineering teams at Quby with bringing data science algorithms from R&D to production and the lessons learned in offering multiple data driven services to hundreds of thousands of users on a daily basis.

Toon, a leading European smart thermostat and energy display, enables users to control and monitor gas and electricity consumption in their homes. Using the energy data we collect from over 400,000 homes we have developed a new Energy Waste Checker app to give actionable advice to end users to ensure that they do not needlessly waste energy. We identify inefficient electrical appliances and suboptimal uses of central heating and hot water by applying disaggregation algorithms to the raw sensor data. In this talk Stephen will describe our how our novel disaggregation algorithms are implemented in Spark and will show how Toon uses cloud-based big data processing to offer data driven services to hundreds of thousands of users.
