What's going on?

The last time we had already shown how a DVB-T Stick with RTL-SDR drivers Installed. Today, we want to put the amount in order to get tendon how easy we first results with our Stick can. We will try to receive various devices in the 433Mhz range, and try to find out whether a neighbor is so kind, and give us his weather data. To do this, we clone the returned Code from git, compile with cmake and install the module.

First, we connect again via SSH to our Raspberry what we, in the meantime, "rasp" have called, we connect so as to "pi" at the "rasp" Syntax: "ssh pi@rasp"

After the Forced Update/Upgrade we will check whether the necessary dependencies are present: "sudo apt-get install libtool libusb-1.0.0-dev, librtlsdr-dev rtl-sdr"

With "git clone https://github.com/merbanan/rtl_433.git" let's get the Code:

Is the Download complete we change with "cd rtl_433" in the newly downloaded directory, create the folder build with "mkdir build" and switch with "cd build/" in the path. After compiling with "cmake ../" we see the following output:

In the connection we can already "make" and "sudo make install" run.

And after the change to the main directory with "cd ~" the program "rtl_433 -G" run.

And find right away a Sensor:

A redirection to a file is without a lot of effort, a distribution of the values via MQTT to a Broker such as Mosquitto is conceivable. And what sparks you?

Super Tutorial.

Ich habe es genauso umgesetzt.

Wie ist denn das Speichern der Werte in einer Datei oder Datenbank möglich?

Danke und Grüße

Habe meinen einen Sensor gefunden :)

Hi,
Ich habe das Projekt auf einem alten Raspberry1 getestet.
Super Anleitung !
Ich habe einen Hinweis:
Mit dem Start: RTL_433 -G sucht er nur die Frequenz 433.920 ab.
Bei mir hat er da nix gefunden
Besser ist Ihr startet das mit: RTL_433 -G -H 600
Dann sucht er aller 600 Millisekunden eine andere Frequenz ab und findet mehr Sensoren.
Grüße
