This repository contains the IoT Center application that provides a web UI that shows how to use InfluxDB v2 in various use cases. It also contains independent clients that write into InfluxDB.

• simple device management, automatic registration of devices in InfluxDB
• arduino, pyton, javasript clients
• various data visualizations, dashboards

• Prerequisites
  • node 14 or newer
  • yarn 1.9.4 or newer

cd app
yarn install
yarn build
yarn start
open http://localhost:5000

or

docker-compose up
open http://localhost:5000

Docker images are available on GitHub Packages with nightly tag:

docker pull ghcr.io/bonitoo-io/iot-center-v2/iot-center:nightly

docker run \
  --name iot-center \
  --detach \
  --env INFLUX_URL=http://10.100.10.100:9999 \
  --env INFLUX_TOKEN=my-token \
  --env INFLUX_ORG=my-org \
  --publish 5000:5000 \
  ghcr.io/bonitoo-io/iot-center-v2/iot-center:nightly

cd app
yarn install
yarn dev

each line in separate terminal, no environment variables has to be set:

cd app/server/mqtt/docker-mosquitto && ./run_mqtt_server.sh
cd app/server && yarn mqtt_dev
cd app/ui && yarn start

Application is running at http://localhost:3000/realtime

Mqtt can be checked with

cd app/server && yarn mqtt_subscriber

Websocket broker (ui side connection) can be checked with

cd app/server && yarn mqtt_subscriber_broker

Register account in InfluxDB Cloud 2 if not exists or install local InfluxDB 2 instance

Edit app/dev.sh and set environment values INFLUX_TOKEN, INFLUX_URL, INFLUX_ORG and uncomment MQTT_TOPIC, MQTT_URL (MQTT_URL can't be localhost or 127.0.0.1 to run with real devices)

Install telegraf and copy example configuration:

cd app/server/mqtt
cp -n telegraf.example.conf telegraf.conf

Edit telegraf.conf and set urls, token, organization under [[outputs.influxdb_v2]] and servers, iot_center under [[inputs.mqtt_consumer]] (to be same as in app/dev.sh):

nano telegraf.conf

Have MQTT Running public or run locally with command:

cd app/server/mqtt/docker-mosquitto && ./run_mqtt_server.sh

Start telgraf:

cd app/server/mqtt && telegraf --config telegraf.conf

Start app:

cd app && ./dev.sh

Mqtt can be checked with:

cd app/server && yarn mqtt_subscriber

Open browser at http://localhost:3000/realtime:

xdg-open http://localhost:3000/realtime

• Install latest node.js
• Install latest yarn
• Download this GIT repository
• Install local InfluxDB 2 instance or register account in InfluxDB Cloud 2 if not exists
• Create admin token
• Set environment variable INFLUX_TOKEN with the admin token from the previous point
• Set environment variable INFLUX_URL (do not use localhost or 127.0.0.1 - IoT Devices need external address)
• Set environment variable INFLUX_ORG
• Run IoT Center
