WeatherDuino 4Pro (Local JSON) – Home Assistant Integration
I’ve released a custom Home Assistant integration specifically for the WeatherDuino 4Pro, reading sensor data locally via HTTP JSON – no cloud, no YAML configuration required.

Quote:⚠️ Important:
At the moment, this integration is tested and confirmed to work only with the WeatherDuino 4Pro.
Other WeatherDuino models may require adjustments to the JSON structure and are not yet supported.

🔧 Key Features

• Local-only integration via the WeatherDuino 4Pro JSON endpoint ( /json)
  
• Config Flow (UI setup) – just enter IP/hostname
  
• Automatic sensor creation
  
• Clean naming (no WeatherDuino <IP>
  prefixes in Home Assistant)
  
• Uses the device-reported ID for proper device naming
  
• Supported sensors (depending on your 4Pro configuration):
  • Temperature & humidity (indoor / outdoor)
    
  • Barometric pressure
    
  • Wind (speed, gust, direction)
    
  • Rain (rate & total today)
    
  • Solar radiation / UV index
    
  • Air quality (CO₂, PM2.5, PM10, AQI)
    
  • Soil moisture sensors
    
  • Additional external sensors (ES1–ES4)
    

📊 Dashboard Examples Included

• Windrose Card (24h / 4h wind distribution)
  
• ApexCharts for wind, gusts and rain history
  
• Rain Gauge Card for daily rainfall
  
• Mushroom Cards for clean status & quick values
  

All Lovelace dashboard examples (including full YAML) are documented in the repository.
📦 Installation

  Settings → Devices & Services → Add Integration
