SMILE, the digital public good for real-time vaccine cold chain monitoring, has reached a significant milestone: over 10,300 daily active users across Indonesia’s 514 kabupaten/kota, with the system now monitoring vaccine storage conditions in thousands of Puskesmas (community health centers) across 17,000+ islands.
From Pilot to National Scale
What began as a pilot project in partnership with UNDP and Kemenkes RI has grown into Indonesia’s national cold chain monitoring backbone. The system’s ClickHouse-powered real-time analytics process millions of data points daily from temperature sensors in vaccine refrigerators, cold rooms, and transport containers.
How It Works
- Sensor Data Collection — Temperature and humidity sensors in cold chain equipment transmit data at configurable intervals
- Real-Time Analytics — ClickHouse processes streaming data with sub-second query performance
- Multi-Channel Alerts — SMS, email, and in-app notifications trigger immediately when temperatures breach safe ranges
- National Dashboard — Centralized view accessible at smile.kemkes.go.id showing real-time status from national to facility level
Global Expansion
Following its success in Indonesia, SMILE has been deployed in Malawi, Africa as eHIN Malawi**, proving that the platform can adapt to different geographies and health system structures.
What’s Next
Update, 9 October 2026: SMILE has since been verified as a digital public good by the Digital Public Goods Alliance. Read the announcement.
