Q: After the connection succeeded and the battery is replaced, the chart shows the data of the last few days, but not the latest


① Please make sure the permissions of Engbird are allowed and the battery is installed correctly.

② Please export the data first, then delete and re-add the sensor (this may result in data loss).

③ If it cannot work, please uninstall and reinstall the app.

④ Please check the version of the sensor. Please go to the settings (between delete and diagram) to confirm the version, and let me know.
