PI Adapter for (generic) MQTT to enable auto-discovery of key value pairs using wildcards
When reading from a generic MQTT broker, we currently need to specify explicitly each key value pairs we want to collect inside the data selection json configuration file. This prevents us from really being agile at the time of the initial setup and for each new information we want to collect, as we need to explicitly define the information manually into the Adapter.
We would like the PI Adapter for (generic) MQTT to be able to capture automatically exposed key value pairs in the MQTT broker following a wildcard pattern. For instance take this example payload:
{
"EquipABC.Location": "0020121047111948",
"EquipABC.Status": "1",
"EquipABC.Flow": "3.14",
"TimeStamp": "2021-02-16T12:28:58.078Z"
}
We would like the PI Adapter to automatically capture [DataStream]:[Value] into the corresponding container using the given timestamp, like for instance the UFL interface/connector can be configured when parsing a file or json payload.
