pi-adhoc-mqtt-cluster

Using batman-adv to connect several raspberrypi to a mesh network and creating a vernemq cluster

Overview

This repo is currently in development and things get added time after time.
Feel free to comment.

Last Update:

• This repo is not updated anymore. It is possible that parts of the batman installation have to be changed because of newer raspbian images and changed drivers.
• The latest configuration (mqtt scripts and Dash visualizations) for multiple raspberry pis can be found in the folder finished_configuration. This includes instructions for starting different sensor scripts which were used for demonstration purposes.
• Perhaps you find some useful information here. Just pick the good bits. Good luck! :)

Used hardware and software

• Raspberry Pi 3 B+

  • batman mesh node (adhoc network wlan0)
  • bridge with lan cable eth0 for combining mesh and different network
  • internet gateway with dhcp server for sharing eth0 internet with mesh nodes
  • mqtt broker cluster node with vernemq
  • grafana/prometheus/influxdb for monitoring mqtt cluster and network (not written yet)
  • Optional: USB Wifi Dongle for wifi client+hotspot configuration and internet sharing

• several Raspberry Pi Zero W (batman mesh node)

  • batman mesh node (adhoc network wlan0)
  • mqtt broker cluster node with vernemq

• OS: Raspbian Stretch Lite (2018-04-18-raspbian-stretch-lite.img)
