NubeIO IoT Platform

IoT Platform provides a distributed system based on micro service that helps to:

• Lightweight and reliable deployments on hundred edge device remotely, while your devices remain online.
• Collect and store IoT data sensors by realtime in time-series database.
• Data Analytics and Data Visualization.

• Development Note

Instruction

Install BACnet on PI

• Install java

  sudo apt update -y \
    && sudo apt install openjdk-8-jre -y \
    && sudo apt autoclean -y \
    && sudo apt autoremove -y

• Download binary into /tmp

  sudo curl -L https://github.com/zero88/gh-release-downloader/releases/download/v1.1.1/ghrd -o /usr/local/bin/ghrd \
    && sudo chmod +x /usr/local/bin/ghrd \
    && sudo ln -s /usr/local/bin/ghrd /usr/bin/ghrd \
    && sudo apt install jq -y
  
  ghrd -a .*bacnet.* -x -t <token_if_repo_is_private> NubeIO/iot-engine -o /tmp

• Register it as service by one liner:

  sudo mkdir -p /app/ \
    && u=$(whoami) \
    && sudo chown -R $u:$u /app \
    && unzip -d /app /tmp/nubeio-edge-connector-bacnet-0.2.1.zip \
    && mv /app/nubeio-edge-connector-bacnet-0.2.1 /app/bacnet \
    && sudo cp -rf /app/bacnet/conf/nubeio-bacnet.service /etc/systemd/system \
    && sudo systemctl daemon-reload \
    && sudo systemctl enable nubeio-bacnet.service \
    && sudo systemctl restart nubeio-bacnet.service

• Application will start at port: 8888

• Verify service: systemctl status nubeio-bacnet.service

• Verify port: netstat -tupln | grep 8888

• Verify service: curl -i localhost:8888/gw/index?_pretty=true

• Any configuration can be modified at /app/conf/bacnet.json. Example config

• Example API. Remember change it to localhost:8888

Tweak config

Assume you install jar file in /app/bacnet.

• Logging: /app/bacnet/conf/logback.xml

  • Change log level to info => error:

    sed -i 's/info/error/g' /app/bacnet/conf/logback.xml

• App config: /app/bacnet/conf/bacnet.json

  • Change log level to 8888 => 9999:

    sed -i 's/"port": 8888/"port": 9999/g' /app/bacnet/conf/bacnet.json

  • Fixed Bacnet Device Id to 81234 (normally it is random number from 80000 to 90000)

    jq --arg deviceId 81234 '.__app__.__bacnet__ += {deviceId: $deviceId}' < conf/bacnet.json > /tmp/bacnet.json \
      && cp -rf /tmp/bacnet.json /app/bacnet/conf/bacnet.json

• Service: /app/bacnet/conf/nubeio-bacnet.service

  • Change memory usage from 150M to 200Mb

    sed -i 's/-XX:MaxRAM=150m/-XX:MaxRAM=200m/g' /app/bacnet/conf/nubeio-bacnet.service

All changes then require restart service.

sudo systemctl restart nubeio-bacnet.service

In case of update memory usage in conf, need to re-update service by

sudo cp -rf /app/bacnet/conf/nubeio-bacnet.service /etc/systemd/system \
    && sudo systemctl daemon-reload \
    && sudo systemctl enable nubeio-bacnet.service \
    && sudo systemctl restart nubeio-bacnet.service
