Why WittIoT
Traditional Weather Stations Are Stuck in the Past
Most personal weather stations give you a tiny LCD screen and that's it. WittIoT changes everything.
Without WittIoT
  • Data locked on a small LCD display
  • No historical trends or analytics
  • Can't share data with family or neighbors
  • No API — impossible to build automations
  • No remote access when you're away
  • Manual unit conversion headaches
With WittIoT
  • Beautiful web dashboard from any device
  • Interactive charts: 24h, 7-day, 30-day views
  • Share via 6-digit shortcode or email invite
  • Full REST API + AI agent integration
  • Access your data anywhere in the world
  • Auto unit conversion in your preferences

Use Cases
Built for Enthusiasts, Powerful Enough for Pros
From backyard gardening to scientific research — WittIoT adapts to your needs.

Home Garden & Agriculture

Monitor temperature, humidity, and rainfall to optimize watering schedules. Set up API-based alerts when frost risk is detected or rain is incoming.

Temperature · Humidity · Rainfall · Light

Education & Research

Give students real-world sensor data to analyze. Use the REST API to build data science projects, or export historical data for statistical analysis.

API Access · Historical Data · 30-Day Trends

Smart Home Automation

Integrate WittIoT data with your home automation system. Close blinds when light exceeds a threshold, or trigger irrigation based on real rainfall data.

REST API · Webhooks · Real-Time Data

Community Weather Network

Share your station publicly via shortcode and contribute to a hyperlocal weather network. Neighbors can check your data without an account.

Public Sharing · Shortcode · No Auth Needed
For Developers

A Weather API That Developers Actually Love

Simple, well-documented, and predictable. Get real-time and historical weather data with a single HTTP request.

  • Real-time readings for all 8 sensors + derived values
  • Historical data: 24-hour, 7-day, and 30-day ranges
  • Public station data via shortcode — no auth needed
  • Full unit conversion: °C/°F, m/s/mph/knots, hPa/inHg, mm/in
  • Rate limiting: 100 req/min (auth) · 30 req/min (public)
  • AI Agent SKILL.md manifest for LLM integration
  • Two auth methods: API Key (X-API-Key) or Bearer Token

AI Integration
Ask Your AI About the Weather Outside
WittIoT ships with a SKILL.md manifest — enabling any AI assistant to query your weather station using natural language.

How It Works

Your AI reads the SKILL.md file, discovers API endpoints, and calls them automatically when you ask weather questions.

  • 1Generate an API key from your WittIoT dashboard
  • 2Configure the key in your AI agent settings
  • 3Ask anything — "What's the temperature?" "Show pressure trends" "Is rain coming?"
  • 4The AI calls WittIoT's REST API and returns a human-readable answer

Can I share my weather data with others?
Yes! Set your station to "public" and share the shortcode link — anyone can view without an account. Or invite specific users by email with granular read permissions.
What can I build with the API?
Smart home automations, gardening alerts, data science projects, custom dashboards, Slack/Discord bots, AI weather assistants — all documented in OpenAPI 3.0 with Swagger UI.
What units are supported?
Temperature (°C/°F), wind (m/s, mph, km/h, knots), pressure (hPa, inHg, mmHg), rainfall (mm, inches). Derived values like dew point and feels-like are calculated automatically.
