I had no problem adding the Google Fit integration to my Wyze Band. Google Fit clearly shows that it is connected to Wyze Band for Heart Rate data and Sleep Data, but it doesn’t sync regularly or sync all info over consistently. When I open up Google Fit, it may sync data from yesterday, but the previous 4 days have no data, then maybe it has data from one day 5 days ago, but not the 7 days prior to that.
My Wyze Band is worn every day all day and in the Wyze Band app, I can see my heart rate, sleep rate, and steps for every day - this info just isn’t getting synced over to Google Fit. I am on the latest version of the app, the latest firmware for the band, and I have completely unauthorized the app with Google Fit, uninstalled the app, re-installed the app, and re-authorized with Google Fit and still have the same issue.
In comparison, I have a smart scale from Eros that has Google Fit integration with their app, and every time I weight myself and record it in the app, it immediately syncs the data over to Google Fit. When I go to Google Fit it has all the data from every day I weighed myself. So this clearly seems to be a programming issue with the Wyze App and the way it syncs with Google Fit. Hoping it can get fixed because I like being able to see all my fitness data in the Google Fit app.
