Been thinking of a project with a bluetooth scale for a long time. Once I saw the Felicita Arc for sale(thank you @"MattH"#780 ) ideas started to form. Not sure how far will this go, but plan is: 1. Create a mobile app to connect to the scale to get the data (done) 2. Create a real time graph for an espresso shot (options to save, add comments and compare with other shots would be cool) 3. Add an arduino bluetooth device inside Lelit Elizabeth and connect it to one of the shot buttons 4. Stop the shot automatically when reaching target weight 5. Connect arduino to the scale directly?
