Exploring 433 MHz Devices in the Neighborhood with RTL-SDR and rtl_433

Over on his YouTube channel CWNE88 has posted how he has been using and RTL-SDR with the rtl_433 software to explore the data coming in from various 433 MHz ISM band devices in his neighborhood. In the video he explains how he has set up rtl_433 on his Raspberry Pi, and what sort of data he is receiving. Some examples of devices he's received include various weather stations, doorbells, remotes and car tyre pressure monitors.

He also mentions how these signals are unencrypted, noting that in a future video he will show on GNU Radio how a false signal could be synthesized.

    after running this software during day time hours, for a few days so far the only thing i managed to capture were TPMS signals from nearby automobiles, and i am happy to say nobody has low or flat tires 🙂

    oh cool, i just set it up, i am hoping one of my neighbors has one of those wireless weather stations, so i can get free weather monitoring by listening to their weather station, if not maybe i will buy one soon,
