Step 4: Adding nodes
cd $HOME/.node-red
npm install <npm-package-name>
replace
sudo npm install node-red-contrib-opi-gpio
Restart Node-RED. Then open web-brownser. Navigate to http://orange_pi_ip:1880/
You can see the result as the picture below
Step 5 (optional): Start Node-RED on boot
Install nodered.service file and start and stop scripts.
sudo wget https://raw.githubusercontent.com/node-red/raspbian-deb-package/master/resources/nodered.service -O /lib/systemd/system/nodered.service
sudo wget https://raw.githubusercontent.com/node-red/raspbian-deb-package/master/resources/node-red-start -O /usr/bin/node-red-start
sudo wget https://raw.githubusercontent.com/node-red/raspbian-deb-package/master/resources/node-red-stop -O /usr/bin/node-red-stop
sudo chmod +x /usr/bin/node-red-st*
sudo systemctl daemon-reload
sudo nano /lib/systemd/system/nodered.service
Edit the nodered.service file as follow:
# systemd service file to start Node-RED
[Unit]
Description=Node-RED graphical event wiring tool.
Wants=network.target
Documentation=http://nodered.org/docs/hardware/raspberrypi.html
[Service]
Type=simple
# Run as root user in order to have access to gpio pins
User=root
Group=root
Nice=5
Environment="NODE_OPTIONS=--max-old-space-size=128"
#Environment="NODE_RED_OPTIONS=-v"
ExecStart=/usr/bin/env node-red-pi $NODE_OPTIONS $NODE_RED_OPTIONS
KillSignal=SIGINT
Restart=on-failure
SyslogIdentifier=Node-RED
[Install]
WantedBy=multi-user.target
To then enable Node-RED to run automatically at every boot
sudo systemctl daemon-reload
sudo systemctl enable nodered.service
It can be disabled by
sudo systemctl disable nodered.service
