crontab or rc.d

Check sudo crontab -e for demons to be started. * I removed them and added them to /etc/init.d/ * init.d vs. cron * rc2.d is the user level stuff
Atention : Don’t forget to set the LSB header.

}
To create psk go with wpa_passphrase "YOURNETWORK"
  • internationalization Options of raspi-config, you have to choice the country for Wi-Fi for DE
  • edit the interfaces file using this command sudo nano /etc/network/interfaces and add the following lines:



auto wlan0
iface wlan0 inet manual

DHT22

„Der linke Pin des Sensors wird an 3V3 von Pi (Pin1) angeschlossen, der zweite Sensor Pin über einen Pull-Up Widerstand (4.7k – 10kΩ) mit einen freien GPIO des Raspberrys (bei mir GPIO4, Pin7) und der rechte Senior Pin kommt an GND (Pin6) vom Pi. Der zweite Pin von rechts des Sensors bleibt frei.“

RCF Outlet

sudo npm install -g homebridge-rfoutlets-protocol Update your homebridge configuration
You need to compile codesend for your CPU architecture (raspberry-remote repo) and replace …/node/lib/node_modules/homebridge-rfoutlets-protocol/codesend with your self compiled version.
In /usr/lib/node_modules/homebridge-rfoutlets-protocol create a symlink sudo ln -s /home/basti/raspberry-remote/send send
Modify /usr/lib/node_modules/homebridge-rfoutlets-protocol to match send instead of codesend (params)

    433 Mhz Remote Control

    Equipment

    • [x] 2 Raspberry Pi’s (zur Not geht auch eines)
    • [x] 433 MHz Sender-Empänger Set (falls beide Pi’s senden und empfangen sollen brauchst du 2 Sets)
    
    git clone git://git.drogon.net/wiringPi && cd wiringPi &&./build
    
    Jetzt brauchen wir noch eine Bibliothek, die es uns einfach ermöglicht unsere Daten über den Sender zu verschicken und über das Empfängermodul zu empfangen.
    
    git clone https://github.com/ninjablocks/433Utils.git --recursive
    
    Diese Bibliothek enthält sowohl für das Arduino, also auch für den Pi entsprechende Skripte. Wir wechseln nun in den Ordner mit den Skripten für das Raspberry Pi und kompilieren diese
    
    
    cd 433Utils/RPi_utils
    make all

    Systemcode ist sozusagen der Schlüssel um die Steckdose ansprechen zu können und sollte somit bei allen Steckdosen gleich sein

    Tips & Tricks

    How to SSH into your Raspberry Pi with a Mac and Ethernet Cable

    how-to-ssh-into-your-raspberry-pi-with-a-mac-and-ethernet-cable

    remote editor

    • ssh -R 52698:localhost:52698 USER@PI
    • rsub xxx

    Get IP address B8:27:EB

    All raspberry devices MAC addresses started with B8:27:EB
    So, on *nix systems, this can be accomplished by executing the following command:
    
    sudo nmap -sP 192.168.1.0/24 | awk '/^Nmap/{ip=$NF}/B8:27:EB/{print ip}'
    
    where 192.168.1.* will be your local network mask. You will get an answer like:
    
    Nmap scan report for raspberrypi.localnetwork.lan (192.168.1.179)
    

    UUID for /etc/fstab

    • verify mounting cat /etc/mtab
    • UUID discovery ls -l /dev/disk/by-uuid/
