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
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

Via HACS (Custom Repository) or manual installation
After installation, add the integration via
Settings → Devices & Services → Add Integration

WeeWx extra data plugin

Mon, 17 Dec 2018 22:03:51 +0000

Hello everybody,

Finally it's the time to release the first (beta) version for the WeeWx WeatherDuino Logger plugin.
This plugin for WeeWx allows you to get all extra data like snow height, AQM data or any extra sensors in full precision to WeeWx weather software.

The principle is very easy, the WeatherDuino logger plugin writes each minute a WeeWx export text file with your desired values. The WeeWx plugin reads this file, checks its currency, and saves it to the WeeWx database.

Attention: The plugin was tested with the Database to use metric units, it should also work with a database in US units (default), but I have not tested it yet.
Please read the included manual carefully. Since the plugin is in a beta stadium, all preconditions have to be like in the test environment, otherwise WeeWx might crash.

Don't forget to make some backups before

Data logging addon

Mon, 23 Jul 2018 20:31:20 +0000

Hello folks,

I would like to introduce my data logging plugin for the WeatherDuino Pro2 Plus.

The plugin allows to log all the captured data in full precision, even that data that may be captured, but can not be transmitted via the Davis Loop Protocol.
At the moment all data is sampled each minute.

The data is saved as *.csv file in readable ascii which can be viewed or processed later on.
There are some changes on the original software by werk necessary and a small hardware modification to get access to the serial port 3 of the Meduino.

Moreover there is a possibility to export a data vector to a software interface to WeeWx to import extra data like a second rain gauge or a snow height measurement.
The corresponding driver for WeeWx is under development at the moment.

Please feel free to suggest any improvements or wishes and use it whenever you like it.

The latest version is working with WeatherDuino software v8 and available via GitHub.

Please read the included manual before using.
