Hello community, I'm developing a mobile application that needs to extract data from Google Health Connect and Apple Health to send it to the backend. Ideally, I want to transmit the data in FHIR format and store it in an appropriate data store. I was considering using AWS HealthLake and AWS TimeStream (for step counts and other time-based biomarkers that I need to track) as the storage solutions. While researching, I found Open mHealth, which has a component called Shimmer (https://github.com/openmhealth/shimmer) that collects data from Google and Apple, but it seems to be outdated. Now, I've also discovered Medplum. I would like to ask for your advice and have a few questions: Can Medplum serve as a replacement for Shimmer, or what would you recommend as an alternative? Can Medplum be used in conjunction with AWS HealthLake? What would you advise for what I'm looking to achieve? I'm highly tied to AWS, but I'm seeking a flexible and cost-effective solution if possible. Thank you very much to anyone who can take a minute to answer any of these questions.
