Edeva, a Swedish company founded in 2009, creates powerful solutions for smart cities using IoT devices to collect data on traffic flow, vehicle classification, bike and pedestrian data, number plate data, gyroscopic data, environmental data, alarm data, status data, and administrative data. The team uses TimescaleDB as the main database in their smart city system, leveraging continuous aggregations to deliver lightning-fast dashboards. With TimescaleDB, they can easily onboard new developers and get accurate percentile values without querying raw data. Edeva's software solutions, such as Actibump and EdevaLive, have made a significant impact on the way people live in smart cities, providing valuable insights for decision-making and improving safety and efficiency. The company is now exploring ways to reduce raw data storage and integrate TimescaleDB with a data lake.
