Sorry, I don't get your point ....
First of all, where do you want to upload your sensor data to ?
E.g. I am uploading the CO2 sensor data, the data of the two WH41 sensors I have, 5 WH51 Soil Moisture sensor data, 5 WH31 extra temperature and humidity sensor data (out of 7, limitation is only on the Meteotemplate end), even one lightning sensor data (out of three, but the limit here is not Meteobridge but Meteotemplate) to Meteotemplate.
When you upload data using a http request (or FTP upload), you define the upload and the sensor descriptors you use.
That's different from the pre-configured uploads to the Weather Networks like WU, AWEKAS, .....
I can give you the example of the upload (published by me already in several posts in this forum) to Meteotemplate:
- and
no mapping done !! - why/what for would I do this ??

PP3=

PP4=
[air0!5-lastval:2]&
CO2_1=

the data arrive and are stored in the respective database fields - all fine.
the Meteotemplate acronyms for better understanding
PP1 = PM2.5 #1 = WH41 (1)
PP2 = PM2.5 #2 = WH41 (2)
PP3 = PM2.5 = WH45
PP4 = PM10 = WH45
CO2_1= CO2 = WH45
(I am repurposing PP4 at the Meteotemplate end as there is no PM10 field in the database)
This is an example for Meteotemplate. But in order to see what you might need, I would first need to know your use case, your scenario.
Any upload with Meteobridge to a server, template, ... would go by the same principle, even if you use text files like realtime.txt or clientraw.txt which you send by FTP.
Mapping, as I understand it, I would do, if I wanted to camouflage data, present a physical sensor under a different name - extremely spoken - send e.g. a temperature value as humidity, or send the data of an extra temperature sensor (WH31) as the outdoor temperature sensor data (WH32) - but I still don't see why I would do this with my WH41/WH45 data. However, without an example and use case description from your end there is a lot of space for talking across purpose.
