WeatherFlow Local for Home Assistant

This a custom component for Home Assistant. It reads real-time data using the UDP protocol from a WeatherFlow weather station.

It will create a device with several sensor entities for each weather reading like Temperature, Humidity, Station Pressure, UV, etc that is associated with it.

Notes:

As this component listens for UDP broadcasts, in can take up to 1 minute before all sensors have gotten a value after restart of Home Assistant

Installation

This Integration can be installed in two ways:

HACS Installation

Add the following to the Custom Repository under Settings in HACS:

briis/smartweatherudp and choose Ìntegration as Category

Manual Installation

  1. If you don't already have a custom_components directory in your Home Assistant config directory, create it.
  2. Copy the smartweatherudp folder under custom_components into the custom_components folder on Home Assistant.
  3. Or using Git, go to the custom_components directory and enter:
    git clone https://github.com/briis/smartweatherudp.git

Track Updates

If installed via HACS, updates are flagged automatically. Otherwise, you will have to manually update as described in the manual installation steps above.

Configuration

There is a config flow for this integration. After installing the custom component:

  1. Go to Configuration->Integrations
  2. Click + ADD INTEGRATION to setup a new integration
  3. Search for WeatherFlow - Local and click on it
  4. You will be guided through the rest of the setup process via the config flow
    • This will initially try to find devices by listening to UDP messages on 0.0.0.0. If no devices are found, it will then ask you to enter a host address to try to listen on. Default is 0.0.0.0 but you can enter any host IP. Typically used if your Weather Station is on a different subnet than Home Assistant.
