In addition to the time series graph, I want to see a prominent "traffic-light-style" display that gives an indication about the current CO2 concentration. It should display three states: green, orange, red. The thresholds must follow the official [recommendation](https://www.umweltbundesamt.de/sites/default/files/medien/2546/dokumente/irk_stellungnahme_lueften_sars-cov-2_0.pdf of the Kommission Innenraumlufthygiene (page 5).
Open issues: In our tests we have seen that current measurement data might not be available because of connectivity issues. What to do then? Gray out the display? How much delay is acceptable?
Display purely as part of the widget.
Complexity: 8
Value: 20
WSJF: 2.5
