yeah! I had picked one up a while ago to play with it and had some fun and stashed it away for a while. Well last week i was BBQing and the receiver end of my little remote temp monitor stopped working. Found rtl_433 that already is setup to read the output from the sender portion and in like 10 minutes had it graphed on grafana with alerts for temps!

Can you show this off? It sounds like something I need to have in my life. What TSDB did you use? What did your conversion from rtl_433 to a metric look like?
It was a bit hacky, i just had rtl_433 output the values as json, piped them into a mqtt topic and used node-red to inject the values in influxdb
nothing fancy
Sir, you just received the most news.ycombinator.comish comment award of the year.

If you set up a HackRF in Chicago, you can hear police dispatch. It's pretty nifty.
