I am working on a project where I need to upload a series of values to InfluxDB so I can have a graph of data. Right now I have Arduino code which generates a random number and stores it my ESP32 flash (LittleFS). I can then read this data in my code as a .txt file. I need help uploading this .txt file from my ESP32 board to influxDB.
You can use InfluxDB’ Arduino client to do the same: GitHub - tobiasschuerg/InfluxDB-Client-for-Arduino: Simple library for sending measurements to an InfluxDB with a single network request. Supports ESP8266 and ESP32. otherwise if you can make an HTTP request you can call write API to write the data into InfluxDB
