Missing sleep data

When I try to tabulate data from Apple Health using the QS iphone app, all I get is the headers in the CSV file. No data, which I know is there. The source is a Xiaomi Mi Band, which works fine with my iPhone and Apple Health. What am I doing wrong?

You could try exporting your Apple Health data through the Hipbone app instead. This will dump your data into a Dropbox folder as a bunch of JSON files, which may be less convenient, but I’m just working on a tool that can process and import those files; let me know if you are interested!
