The Dashboard is an art installation in the Otter Space between the server room and the kitchen passage. It currently displays a few interesting stats about the Metalab, mostly concerning the drink sales.
It is currently just a Raspberry Pi 3 running FullPageOS. Its web browser opens a Grafana public dashboard hosted on the SmartLab server.
Version 2
Version 1 is ok, but it has several shortcomings stemming from the fact that Grafana not being designed for this kind of use case (public dashboards). Other solutions should be evaluated.

The Flutter solution is the most work, because it requires software development rather than just configuration. The idea is to use Charts Painter to write a regular Flutter application that then uses flutter-pi to run on the device (automatically after boot).
Another option for a custom application would be Dash which does the same thing in Python.
anlumo invites everybody else to evaluate other solutions and append another column on the table above!
