Updates, milestones, and insights from the team behind SMILE — the open-source Digital Public Good powering vaccine cold chain monitoring across Indonesia's 514 kabupaten/kota and its deployment as eHIN in Malawi. Here we cover product releases, field deployment notes from health workers and Puskesmas, integration updates for partners running FHIR-based health data platforms, and lessons from scaling an open-source system across two continents. If you work in immunization logistics, cold chain monitoring, or digital public goods, this is where we document what we're building and why.
