rainy - a tiny tool for iot data collection and monitoring

rainy is a tiny tool for IoT data collection and monitoring, and supports the following devices and protocols:

These data can be sent to InfluxDB (Time Series Database) for visualization, or sent to MQTT Broker to be used as a data source for any other purposes.

rainy runs on Apache Felix (OSGi). I think that rainy can be embedded in the environment without OSGi.

I releases this in the form of the Eclipse plug-in project and this tool - rainy-felix.zip. The list of my source codes and third party bundles is Bundle list. You need Java 8. I have confirmed that it works in Raspberry Pi 3B (Raspbian Buster Lite OS (2019-07-10)).

The following figure is overview of rainy.

The following figure is overview which the monitoring is running together with rainy on same Raspberry Pi 3B. I checked easily that it also works with Raspberry Pi 4B.

The following image shows the hardware configuration.

Table of Contents

Purpose

The purpose of this tool is briefly as follows.

  • For private / office / factory room, easily collect general environmental information and industrial / factory equipment running information via OPC-UA.
  • Real-time monitoring and convert these information to MQTT as a data source for any other purposes.
  • Runs as Java / OSGi application on Raspberry Pi 3B (arm) and Ubuntu machine (amd64).

The concept is as follows.

Although I think the functionality and performance of this tool are not sufficient for formal operation, it may be an easy-to-try tool.

Setup OS

Please refer to here for setting RaspberryPi 3B as an environment for running rainy. Both Bluetooth, serial communication, GPIO and I2C can be enabled.

Setup sending data

rainy supports InfluxDB and MQTT broker as sending data.

Install InfluxDB and startup

I am using InfluxDB on Ubuntu 18.04. The installation is as follows from here.

# wget https://dl.influxdata.com/influxdb/releases/influxdb_1.7.8_amd64.deb
# dpkg -i influxdb_1.7.8_amd64.deb
# systemctl enable influxdb.service
# systemctl start influxdb.service

In addition, the step to install InfluxDB on Raspberry Pi 3B is as follows.

# wget https://dl.influxdata.com/influxdb/releases/influxdb_1.7.8_armhf.deb
# dpkg -i influxdb_1.7.8_armhf.deb
# systemctl enable influxdb.service
# systemctl start influxdb.service

Install Mosquitto (MQTT Broker) and startup

I am using Mosquitto as MQTT broker on Ubuntu 18.04. The installation is as follows.

# apt-get update
# apt-get install mosquitto
# apt-get install mosquitto-clients
# systemctl enable mosquitto.service
# systemctl start mosquitto.service

In addition, the step to install Mosquitto on Raspberry Pi 3B is the same as above.

Setup visualization tools

Install Grafana and startup

I am using Grafana on Ubuntu 18.04. The installation is as follows from here.

# wget https://dl.grafana.com/oss/release/grafana_6.4.3_amd64.deb
# dpkg -i grafana_6.4.3_amd64.deb
# systemctl enable grafana-server.service
# systemctl start grafana-server.service

In addition, the step to install Grafana on Raspberry Pi 3B is as follows.

# wget https://dl.grafana.com/oss/release/grafana_6.4.3_armhf.deb
# dpkg -i grafana_6.4.3_armhf.deb
# systemctl enable grafana-server.service
# systemctl start grafana-server.service

Install Chronograf and startup

I am using Chronograf on Ubuntu 18.04. The installation is as follows from here.

# wget https://dl.influxdata.com/chronograf/releases/chronograf_1.7.14_amd64.deb
# dpkg -i chronograf_1.7.14_amd64.deb
# systemctl enable chronograf.service
# systemctl start chronograf.service

In addition, the step to install Chronograf on Raspberry Pi 3B is as follows.

# wget https://dl.influxdata.com/chronograf/releases/chronograf_1.7.14_armhf.deb
# dpkg -i chronograf_1.7.14_armhf.deb
# systemctl enable chronograf.service
# systemctl start chronograf.service

Testing HTTPS connection with self-signed certificate

In general, it is not recommended to use a self-signed certificate for formal operation, but it is sufficient for testing purposes.

Create a self-signed certificate and private key with file names cert.pem and cert.key

# openssl req -x509 -newkey rsa:4096 -sha256 -nodes -keyout cert.key -out cert.pem -subj "/CN=localhost" -days 365

Create /etc/rainy directory and place these files there

# mkdir /etc/rainy
# cp cert.pem cert.key /etc/rainy/
# cd /etc/rainy
# chmod 0644 cert.pem cert.key

      default is 1.
  • nodeIDs
    List the target node ID. The format is as follows. 
    <namespaceIndex>,<identifier>,<depth>

    nodeIDs=2,Dynamic/RandomInt32,0 \
    2,Dynamic/RandomInt64,0 \
    2,Dynamic,-1 \
    0,2295,-1
    In the above example, specify 2,Dynamic/RandomInt32 and 2,Dynamic/RandomInt64 uniquely, and search for the NodeID to be monitored from 2,Dynamic and 0,2295(VendorServerInfo) at an infinite depth. In this case, only 2,Dynamic,-1 and 0,2295,-1 should be specified, but I wrote it for explanation of the format.

conf/opcua also contains a milo-example.properties file. This is an example server-properties file of connecting to the server (milo-example-server) where the Milo sample server code is built almost as it is.

For reference, there is toem impulse OPC/UA Extension (Eclipse pulug-in) as a tool for easily checking the address space of OPC-UA server.

In order to reduce writing to the SD card, it is usually recommended to set it to INFO.

Check the database name for each device created in InfluxDB

Check from the log file logs/rainy.log.0. The following is an example. Note that InfluxDB will not do anything if the database already exists.

execute - CREATE DATABASE RP3B_01__dev_ttyAMA0               <-- MH-Z19B
...
execute - CREATE DATABASE RP3B_01_I2C_1_76                   <-- BME280
...
execute - CREATE DATABASE RP3B_01_I2C_1_23                   <-- BH1750FVI
...
execute - CREATE DATABASE B0_B4_48_B9_92_86                  <-- CC2650
...
execute - CREATE DATABASE B0_B4_48_ED_B6_04                  <-- CC2650
...
execute - CREATE DATABASE milo_digitalpetri_com_62541_milo   <-- Public Demo Server of Eclipse Milo
...
execute - CREATE DATABASE RP3B_01_GPIO_10                    <-- PPD42NS
...
execute - CREATE DATABASE RP3B_01_GPIO_18                    <-- RCWL-0516
...
execute - CREATE DATABASE RP3B_01_GPIO_19                    <-- HC-SR501

These database names are required for the visualization tools Grafana and Chronograf to connect to InfluxDB.

Create dashboards with visualization tools

Visualization tools can be connected to InfluxDB to monitor time-series sensor data.

Case Grafana

Please refer to Getting started of Grafana site for how to use Grafana.
The following figure is a sample image of a dashboard.

The following figure is a sample graph of Magnetometer using Plotly panel.

The following figure is a sample monitoring image with environmental information on the floor map using ImageIt panel.

Case Chronograf

Please refer to Getting started of Chronograf site for how to use Chronograf.
The following figure is a sample image of a dashboard.

The following figure is a sample dashboard for the following NodeIDs on OPC-UA Public Demo Server of Eclipse Milo.

  • 1,VendorServerInfo/ProcessCpuLoad
  • 1,VendorServerInfo/SystemCpuLoad
  • 1,VendorServerInfo/UsedMemory
  • 2,Dynamic/RandomDouble
  • 2,Dynamic/RandomFloat
  • 2,Dynamic/RandomInt32
  • 2,Dynamic/RandomInt64

The upper displays 1,VendorServerInfo/ProcessCpuLoad, 1,VendorServerInfo/SystemCpuLoad and 1, VendorServerInfo/UsedMemory. The middle displays 2,Dynamic/RandomDouble and 2,Dynamic/RandomFloat superimposed and the lower displays 2,Dynamic/RandomInt32 and 2,Dynamic/RandomInt64 as time series graphs.

If you put data into InfluxDB which is a time series DB, you can easily create a dashboard using Grafana or Chronograf.

Check the data sent to MQTT broker

Check the data sent to the MQTT broker using the MQTT client command as follows:

Limitations

  • Only one Bluetooth adapter can be used.
  • Only a few CC2650 (Bluetooth devices) can be used at the same time. (Restriction of Bluetooth chip)
  • When the connection with CC2650 is lost, it may not recover automatically.
  • This tool uses Pi4J for BME280/BH1750FVI/PPD42NS/RCWL-0516/HC-SR501, so these devices can only be used with Raspberry Pi series (arm). Therefore, the the features of these devices of this tool does not work on amd64 Linux machines.
  • To use Pi4J 1.2's I2C functionality, sun.misc.SharedSecrets.class is required, but this class can only be used up to Java 8 and cannot be used since Java 9. Therefore, Java 8 is required to use BME280 and BH1750FVI.
  • Depending on the combination of the number of monitored items of OPC-UA servers and the publishing interval, the load on InfluxDB may become too large.

Bundle list

The following bundles I created follow the MIT license.

Please check each license for the following bundles used in addition to these.

I would like to thank the authors of these very useful codes, and all the contributors.

P.S.

If Raspberry Pi 4B (4GB memory model), InfluxDB and Grafana may be able to run together with rainy in enough resources. In this case, from sensor data collection to monitoring, it may be possible to run with one RP4.
