Catalog neighborhood devices and analyze SNR

[hdtodd]

In using my RTL_SDR dongle to collect temperature data from my Acurite remote sensor, I noticed that there are a number of other devices in my neighborhood sending signals on the 433MHz band. I wondered what else is out there and how well other thermometer readings correlated with mine. But first I had to know what was in the neighborhood.

So I wrote a pair of programs, snr (C) and SNR.py (Python), to analyze rtl_433 JSON logs and catalog and analyze signals (specifically the signal-to-noise ratio) from devices recorded in the logs. I was astounded at the number and variety of devices in our (rather small and isolated) neighborhood.

These programs might be useful to others. They're available on github:

Open list of ideas:

• PR Update LINKS.md #2120 to https://github.com/merbanan/rtl_433/blob/master/docs/LINKS.md
• Add reading from the HTTP-API for live updates.
• Port to JS to use on our HTTP UI

Now that this is in LINKS, should this discussion be closed out?
