@Tboxranger I don't use a Eufy scale, but I here is the link to Fitbit's Help article for help with a third party app.
I also moved your post to the Third-party Integration forum, a better fit for your issue. You might get more help if you edit your title to Eufy scale. Tap on the circle with the down arrow in the upper right of your thread. There is an Edit option in the dropdown.
