EnerKey's IoT platform uses InfluxDB Enterprise and Microsoft Azure to analyze sensor data from various sources, enabling customers to save millions of euros by detecting energy usage fluctuations triggered by weather and geospatial data. EnerKey's CTO Martti Kontula presented on how the company powers its platform using InfluxDB and Azure, showcasing their 80+ out-of-the-box integrations with various data sources. The platform helps commercial real estate owners and managing companies understand their facilities better by collecting time series data in real-time, analyzing it, and storing raw data in InfluxDB while metadata is stored in Azure SQL. EnerKey had previously considered other options like PostgreSQL, MongoDB, and Cassandra before choosing InfluxDB Enterprise due to its high ingest and output rates and key functionalities. The company is now using InfluxDB and machine learning models for advanced analytics to further enhance their competitive advantage.
