Setting up NodeRED on a Raspberry Pi.

1. Install NodeRED from the script.
   • https://nodered.org/docs/getting-started/raspberrypi#running-as-a-service
2. Install Mosquitto MQTT broker.
   • sudo apt install mosquitto mosquitto-clients
   • run sudo systemctl enable mosquitto.service to enable the service
   • edit /etc/mosquitto/mosquitto.conf
   • add the following to lines to the bottom of the file
     • listener 1883
     • allow_anonymous true
   • restart the broker sudo systemctl restart mosquitto
   • run sudo mosquitto_passwd -c /etc/mosquitto/passwd YOUR_USERNAME
   • edit /etc/mosquitto/mosquitto.conf
   • remove the previous two added lines
   • add per_listener_settings true to the top of the file
   • add to bottom of the file
     • allow_anonymous false
     • listener 1883
     • password_file /etc/mosquitto/passwd
   • restart the broker sudo systemctl restart mosquitto
3. Install zigbee2mqtt
   • You can follow the install guide here.
   • It may be a good idea to follow the instruction for disabling file log output.
4. Once installed, install node-red-contrib-zigbee2mqtt

Now that you've got the basics setup, it's time to configure NodeRED.

1. Add a Zigbee2mqtt Bridge item, and configure the details you setup for your mqtt broker.
2. Pair any devices in the Zigbee2mqtt frontend. By default, it runs on port 8080 on localhost.
