Download and install Raspian Stretch Lite onto RasPi SD card
-
sudo raspi-config
- Enable SSL and any other desired options
Connect remotely using Putty:
Connect via SSH to the Pi’s IP address
Update and install all of the necessary software:
sudo raspi-update sudo reboot
after the reboot, log in and install Node-Red
sudo apt-get install nodered
Once installed, we will need to start Node Red by running the following code.
node-red-start
Now you can go to the Pi’s IP address in any web browser but be sure to add port 1880 to the IP address like so:
http://192.168.1.32:1880
Now we want to make it so Node RED runs on startup.
sudo systemctl enable nodered.serviceinstall MQTT support
sudo wget http://repo.mosquitto.org/debian/mosquitto-repo.gpg.key sudo apt-key add mosquitto-repo.gpg.key cd /etc/apt/sources.list.d/ sudo wget http://repo.mosquitto.org/debian/mosquitto-wheezy.list sudo apt-get update sudo apt-get -y install mosquitto mosquitto-clients python-mosquitto
Test by starting the service
sudo /etc/init.d/mosquitto start
open a new Putty terminal
In the first terminal enter the following:
mosquitto_sub -d -t hello/world
In the second Window, enter:
mosquitto_pub -d -t hello/world -m "Hellow from Terminal 2!"
If successful, the packet sent from terminal window 2 should appear in window.
Great tutorial. Notes that helped me as a n00b:
1. After installing raspbian/raspbian lite, and before ejecting the disk, you can create a blank file in the boot partition called “ssh” to enable access with the password “raspberry.”
2. To install python support I followed these steps: https://theembeddedlab.com/tutorials/install-mosquitto-on-a-raspberry-pi/
Everything else worked like a charm…
