Shigeru,

Thank you for sharing this with us! It looks very interesting.

Hi Kevin and everyone,

I have created a tiny tool that collects IoT data, visualizes it and sends it to MQTT broker.

It is running on Raspberry Pi 3B.

https://github.com/s5uishida/rainy

The following IoT data is supported.

- OPC-UA

  using Milo.

- Environmental information

  - TI SensorTag CC2650 (Temperature / Humidity / Barometric pressure / Illuminance)

    using bluez-dbus (https://github.com/hypfvieh/bluez-dbus) for BluetoothLE communication.

  - MH-Z19B (CO2 gas concentration)

    using jSerialComm (https://github.com/Fazecast/jSerialComm) for serial communication (GPIO).

It uses InfluxDB for the time series DB. By storing IoT data as time series data, you can easily

create a dashboard with Grafana or Chronograf.

InfluxDB and Grafana / Chronograf are running on other virtual machines (Ubuntu 18.04).
If the Raspberry Pi 4B 4GB memory model, this tool may be able to run these together.
If so, I think it will be closer to "tiny".

Also, as a sample server for OPC-UA, a connection setting file for Milo public demo server is included.

Please let me know if it is inconvenient.

Regards,

--Shigeru
