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.
| Requirement | Grafana | Home Assistant | Flutter Implementation |
|---|---|---|---|
| Starts on a Raspberry Pi without user interaction | alpha state | ✘ | ✔ |
| Basic bar charts | ✔ | ✘ | ✔ |
| Multi-series bar charts | ✔ | ✘ | ✘ |
| Basic line charts | ✔ | ✘ | ✔ |
| Moving average line charts | ✔ | ✘ | ✔ |
| Cropping outliers from charts | ✘ | ✘ | ✔ |
| Free color choice | ✘ | ✘ | ✔ |
| Displaying binary live data | ✘ | ✔ | ✔ |
| Displaying live text messages | ✘ | ✔ | ✔ |
| Autoswitching between multiple screens | ✘ | ✘ | ✔ |
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).
anlumo invites everybody else to evaluate other solutions and append another column on the table above!
