The OI4 adapter facilitates the integration of any OT-device compliant with the OI4 standard into Apache StreamPipes. For detailed information about this standard, please refer to their development guide.
Your OI4-compatible device should emit data via an MQTT broker.
This adapter exclusively allows data consumption from a specific MQTT topic. If you have different requirements, please notify us through the mailing list or GitHub discussions.
Below is a list of the configuration parameters you need to provide.
Enter the URL of the broker, including the protocol and port number (e.g., tcp://10.20.10.3:1883).
Choose between unauthenticated access or input your credentials for authenticated access.
You should provide information about the sensor you want to connect to. This can be achieved in two ways:
a) By Type: Specify the type of sensor you want to connect to, e.g., 'VVB001'. <\br> b) By IODD: Simply upload the IODD description of the respective sensor. Please note: This feature is not yet available! If you're interested in this feature, please notify us through the mailing list or GitHub discussions and share your use case with us.
Configure which sensors of the master device you want to connect to. You can either select All, which will provide data from all sensors available on the respective MQTT topic, or choose Custom Selection and provide a list of sensor IDs in a comma-separated string (e.g., 000008740649,000008740672).
The output consists of all values from the selected sensor type. Below is an example for the VVB001 sensor:
{ "a-Rms": 1.8, "OUT2": true, "SensorID": "000008740649", "Temperature": 22, "Crest": 3.7, "v-Rms": 0.0023, "OUT1": true, "Device status": 0, "timestamp": 1685525380729 }
