A simple way to log data from your ESP8266 to an InfluxDB server using the HTTP API. Designed for use in the ESP8266 Core for Arduino enviroment.

Does it work? It seems to! Please open an issue / contribute a pull request if you have fixes, features, optomizations, issues, etc.

#TODO:

• Update multiple fields at once
• Authentication support
• More update functions for various data types
• Better support for floats

Create a database object with some info about your database!

const char * host = "192.168.1.152";  // ip or domain name
uint16_t port = 8086; // Port your server is listening for data on. Default is 8086

ESP8266InfluxClient influx_server = ESP8266InfluxClient(host, port);

Create a Measurement struct with the settings for the specific field you want to update.
If you're logging multiple measurements, create multiple structs with the relevant info for each.

Measurement bedroom_temp = {
  "house_iot_data",  // Database name
  "bedroom",   // Measurement name
  "fahrenheit",      // Field key
  "bedroom-esp8266-01", // Host name (A name or unique id for the sensor)
  "us-east"     // Region
};

Pass that function, and a value, to the update function!

influx_server.update(bedroom_temp, read_temp());
