I wanted my family to see the latest info on how bad COVID-19 spread is getting lately, without having to tell them every day. I realized the Hubitat could scrape some info and display it on our dashboard. It probably took me less than an hour to find something and make it work!
In Maryland, we have a good site for returning data about testing results from their arcgis page, in JSON. So I hacked a little JSON parser that I found on the forums:
https://community.hubitat.com/t/help-with-simple-http-query-device-driver
And now I pull the 7-day average of new infections per 100k population directly from the Maryland arcgis site and display it using the Hubigraph heat map graph. Bad values are red, concerning values are orange, then yellow, then green for very little community spread. Now it looks like this:
(yesterday was 35.0, it keeps going up)
The code I hacked together follows:

log.warn "debug logging disabled..."

}

unschedule()

log.warn "debug logging is: ${logEnable == true}"
if (logEnable) runIn(1800, logsOff)
if(updateMins != "0") {
