Seoul Realtime

Know what is happening across Seoul before you step outside. This app connects to the Seoul Open Data Plaza's real-time city data feed and turns crowd levels, weather conditions, road traffic, and air quality into live Homey sensor devices for 121 key locations — from Gyeongbokgung Palace and Hongdae to Yeouido and the Han River parks. Each place becomes a device you can monitor on your Homey dashboard, include in Flows, and track over time with Insights. Whether you want an automation that warns you when your favourite park gets too crowded, or simply want to glance at current conditions before heading out, every sensor updates automatically at the interval you choose.
