(for exemple deveui, devadr, fcnt, gateways id, etc)
I want to use this feature to bring data parsing to the influxdb integration (for example splitting device name composed by sensor ID and location of sensor). The idea is to avoid multiple data base with the same information.
In the current implementation, this is not possible as the codec functions are only for the payload. It is not designed as a middleware to change other meta-data. When this would be possible in the JS codec functions, this would not be accessible when selecting a pre-configured codec like Cayenne LPP.
Please note that the device name is used for the InfluxDB measurement names, you could also put the extra meta-data in the device description, to avoid it will end up in InfluxDB?
I am using meta data for integrating data into influxdb. And I understand that it is not the use case of the app server. But I am also using some metadata to decode my payload. The count ism used for exemple to generate a packet/timestamping location of my data, and also I am using deveui to consolidate my data. Maybe this use case is not adapted to the decoding parser
