Weather Station InfluxDB Logger

A lightweight, high-performance Go application that acts as a bridge between Personal Weather Stations (PWS) and InfluxDB v2. It listens for HTTP GET requests (standard PWS upload format), parses the query parameters, calculates derived metrics (like Dew Point), and writes the data to an InfluxDB bucket.

Features

• Fast & Efficient: Refactored to remove heavy reflection; uses direct type parsing.
• Automatic Calculations: Calculates Dew Point (Indoor and Outdoor) based on temperature and humidity.
• InfluxDB v2 Support: Native support for InfluxDB 2.x using the official Go client.
• Container Ready: Includes Dockerfile and instructions for containerized deployment.
• Structured Logging: Uses Go's slog for clear, standard log output.

Quick Start (Docker)

The easiest way to run this is using the pre-built Docker image.

Option 1: Docker CLI

Note: Replace 192.168.1.x with the actual IP address of your InfluxDB server. Do not use localhost inside the container.

docker run -d \
  --name weather-receiver \
  -p 8080:8080 \
  -e INFLUXDB_URL="http://192.168.1.x:8086" \
  -e INFLUXDB_ORG="my-org" \
  -e INFLUXDB_BUCKET="weather" \
  -e INFLUXDB_TOKEN="your-token-here" \
  slydog/weather-receiver:latest

Option 2: Docker Compose

Create a docker-compose.yml:

services:
  weather-receiver:
    image: slydog/weather-receiver:latest
    container_name: weather-receiver
    restart: unless-stopped
    ports:
      - "8080:8080"
    environment:
      # CRITICAL: Do not use "localhost". Use the actual IP of the InfluxDB server.
      - INFLUXDB_URL=http://192.168.1.50:8086
      - INFLUXDB_ORG=my-org
      - INFLUXDB_BUCKET=weather
      - INFLUXDB_TOKEN=my-super-secret-token

Then run:

docker-compose up -d

Setup Your Weather Station

Configure your weather station (Ambient Weather, Ecowitt, etc.) to use the "Custom Server" settings:

• Server/Hostname: The IP address of the machine running this container.
• Port: 8080
• Path: / (Root)
• Station ID/Key: (Optional, will be logged as the passkey tag).

Configuration Reference

The application is configured primarily via Environment Variables.

Variable	Description	Example
INFLUXDB_URL	The URL of your InfluxDB server	http://192.168.1.50:8086
INFLUXDB_TOKEN	Your InfluxDB API Token	your-super-secret-token
INFLUXDB_ORG	Your InfluxDB Organization name	my-org
INFLUXDB_BUCKET	The bucket to write data to	weather

Command Line Flags (For running from source)

Flag	Default	Description
-port	8080	The HTTP port the server listens on

Building from Source (Development)

If you want to modify the code or build the container locally:

Prerequisites:

• Go 1.24+
• Docker

Build & Run with Compose: This repository includes a docker-compose.yml configured to build from source.

1. Edit docker-compose.yml to set your environment variables.
2. Run:

   docker-compose up -d --build
