Home Assistant Integration for WeatherFlow Stations

WeatherFlow Weather for Home Assistant

GitHub release (latest by date) hacs_badge

UPDATE DECEMBER 2023

This integration is now been Archieved, please use this integration instead, which is fully maintained and does not have any conflicts with the new core integration: WeatherFlow Forecast and Sensor integration for Home Assistant The Integration will be removed from the default HACS store

‼️ DEPRECATION WARNING

As of Home Assistant 2023.10 there is now a new WeatherFlow core integration, which uses the same domain name as this integration - that means that both of these integrations cannot run at the same time. The difference between the two integrations are:

  • The core WeatherFlow integration uses the UDP API, making it 100% local, and independent of an internet connection.
  • This Integration uses the Rest API, which requires an Internet connection to work.
  • This integration has a lot more sensors available and also delivers a Weather Forecast

Instead of just renaming the domain name of this integration, I decided to re-write it completely, with a new name and more up-to-date coding. The new integration is called WeatherFlow Forecast and Sensor integration for Home Assistant and is available for testing now.

Timing: As soon as the new Integration is accepted in the default HACS store, this integration will be removed from there, and this Integration will be archived. I do not recommend new users to install this integration but instead use the new one.

Overview

The WeatherFlow integration adds support for retrieving weather data from a Personal Weatherstation manufactured by WeatherFlow using a REST API.

There is currently support for the following device types within Home Assistant:

  • Weather
    • Two Weather entities will be created per station. One showing an hour-based forecast and one showing a day based forecast.
  • Sensor
    • A whole range of individual sensors will be available. for a complete list of the sensors, see the list below.
  • Binary Sensor
    • A few binary sensors will be available, that can be used to trigger automations, if f.ex. it starts raining.

Installation

HACS installation

This Integration is part of the default HACS store. Search for weatherflow weather under Integrations and install from there. After the installation of the files, you must restart Home Assistant, or else you will not be able to add WeatherFlow Weather from the Integration Page.

If you are not familiar with HACS, or haven't installed it, I would recommend to look through the HACS documentation, before continuing. Even though you can install the Integration manually, I would recommend using HACS, as you would always be reminded when a new release is published.

Manual installation

To add WeatherFlow to your installation, create this folder structure in your /config directory:

custom_components/weatherflow.

Then drop the following files into that folder:

__init__.py
binary_sensor.py
config_flow.py
const.py
entity.py
manifest.json
models.py
sensor.py
weather.py
translation (Directory with all files)

Configuration

To add WeatherFlow Weather to your installation, do the following:

  • Go to Configuration and Integrations
  • Click the + ADD INTEGRATION button in the lower right corner.
  • Search for WeatherFlow and click the integration.
  • When loaded, there will be a configuration box, where you must enter your Station ID and a Personal Token to get access to your data. When entered click Submit and the Integration will load all the entities.

If you want to change the update frequencies for the realtime data and forecast data, this can be done by clicking CONFIGURE in the lower left corner of the WeatherFlow integration..

You can configure more than 1 instance of the Integration by using a different Station ID.

Token for WeatherFlow

The WeatherFlow REST API requires a Token. Please login with your account and create the token. Go to Settings and choose Data Authorizations (almost at the bottom). Create a personal access token and use that as Token (API key).

Please Note: The Token you create here will ONLY work with Stations that are registered under the same Login.

Station ID

Each WeatherFlow Station you setup, will get a unique Station ID, this id is needed during configuration. To get your Station ID, login with your account, select the station on the list, and then click Status. Here you will find your Station ID.

Available Sensors

Here is the list of sensors that the program generates. Calculated Sensor means, if No, then data comes directly from the Weather Station, if yes, it is a sensor that is derived from some of the other sensors. Not all sensors show up on all installations. It depends on the Physical Device you have and where in the world your station is located.

Available Binary Sensors

Here is the list of binary sensors that the program generates. These sensors are all calculated based on values from other sensors

is_raining Is Raining Is it raining outside

Available Weather Entities

Here is the list of Weather Entities that the program generates. With the exception of the condition state and the icon, the values for the current condition are equal to the Sensor values, so the Weather entity displayes realtime values and the forecast for either the next days or the next hours. Both entities are installed.

All entities are prefixed with weatherflow_ and names are prefixed with Weatherflow

Sensor ID Name Description
day_based_forecast Day Based Forecast A weather entity with Forecast for today and the next 9 days
hourly_based_forecast Hourly Based Forecast A weather entity with Forecast for the next 48 hours

Enable Debug Logging

If logs are needed for debugging or reporting an issue, use the following configuration.yaml:

logger:
  default: error
  logs:
    pyweatherflowrest: debug
    custom_components.weatherflow: debug

CONTRIBUTE TO THE PROJECT AND DEVELOPING WITH A DEVCONTAINER

Integration

  1. Fork and clone the repository.
  2. Open in VSCode and choose to open in devcontainer. Must have VSCode devcontainer prerequisites.
  3. Run the command container start from VSCode terminal
  4. A fresh Home Assistant test instance will install and will eventually be running on port 9124 with this integration running
  5. When the container is running, go to http://localhost:9124 and the add WeatherFlow Weather from the Integration Page.

Frontend

There are some sensors in this integration that provides a text as state which is not covered by the core Frontend translation. Example: sensor.weatherflow_pressure_tend, sensor.weatherflow_uv_description and sensor.weatherflow_beaufort_description.

As default the text in the Frontend is displayed in english if your language is not present in this integration, but if you want to help translate these texts into a new language, please do the following:

  • Go to the translations directory under custom_components/weatherflow and copy the file sensor.en.json to sensor.YOUR_LANGUAGE_CODE.json in a directory on your computer.
  • Edit the file and change all the descriptions to your language.
  • Make a Pull request in this Github and attach your new file.

The same procedure applies for the Configuration flow, follow the above procedure, just copy en.json to YOUR_LANGUAGE_CODE.json.
