Gründau keeps its smart city close to everyday life. Since July 2025 a live 'heat map' on the town homepage has shown temperature, humidity and pressure from sensors at seven playgrounds, carried over a municipal LoRaWAN network built since 2022. Paired with a two-year intercommunal climate-adaptation strategy, it turns cheap sensors into something parents can actually use.
