 ### Epic v1: Chicken scale recognizes weight change and sends message about state (which chicken, an egg) via Whatsapp
 
-* Story: (done) create Webservice GET base
-* Story: (done) using Github Actions to automatic build and create an image
-* Story: (done) install current Docker image on Raspberry PI and start it initially
-* Story: (done) create structure with timer service pulling dummy scale service and show data via GET service
-* Story: (done) give calibrate webservice operation for load cell
-* Story: (done) create scale service that delivers current weight

-* Story: change discovery webserivce to use DO instead of strings
 * Story: write tests and mock for scale service
 * Story: respect box/UID of load cell
