I have the LEDs on this switch by our front door connected to a script that gets COVID rna concentration levels from the Boston-area sewage system. It&#39;s _never_ been down to just one dot like this before!

@mattdm This is excellent. What switch? How are you doing this? Home Assistant?

@mattdm@hachyderm.io ....and not just because they've changed how they report numbers, right?? (I have no reason to believe Boston has done so, but I've seen it happen elsewhere.)

@mattdm@hachyderm.io @janeadams@datavis.social That’s a great hack. What’s the latency on the data in your area? Here, we’re only ever operating with data 1-3 weeks after it was sampled, which cuts down on proactivity considerably.

@mattdm@hachyderm.io This should be a billboard in every city and a source of civic pride.
