This page shows the online version of meBarista for Chrome: it can be used to ‘play back’ recorded sessions from sharing through meBarista.
This is actual data captured using a meCoffee with dual sensors installed and shared via the share functionality of meBarista. The black line is the Rancilio Silvia controlled by meCoffee PID and the red line is the temperature of a stock Silvia.
Both machine were at room temperature and started at the same time.
Notice the temperature swing of about 25 degrees Celcius. The playback speed default to 50 times realtime.
