It appears that when a sensor goes offline CanberraAir continues to show the last seen air quality from that sensor even though the sensor is no longer updating and the air quality has changed. E.g. the "N. Cbr" sensor has been offline for 20 hours at the time of writing and shows up grey on the PurpleAir map, but CanberraAir continues to show
N. Cbr: 77 (19 PM2.5) worsening | 10min: 64 (16 PM2.5) | 30min: 62 (15 PM2.5)
I propose that a sensor either doesn't show up if it's offline or it explicitly says it's offline.
