Weather Station to Home Assistant Relay

This project provides a python script solution for ingesting weather data from a VEVOR 7-in-1 Wi-Fi Solar Self-Charging Weather Station (Model YT60234, or any station sending data in Weather Underground format) and forwarding it to Home Assistant via MQTT.

---

Features

• Accepts Weather Underground (WU) station GET requests (as sent by the VEVOR weather station)
• Converts measurements to metric or imperial units based on the UNITS environment variable
• Publishes sensor data to Home Assistant via MQTT using the auto-discovery format
• All sensors appear under one device in Home Assistant
• Responds with success so the weather station doesn’t retry

Quickstart

1. Prepare Linux OS (Debian)

sudo apt-get update
sudo apt-get install git
sudo apt-get install python3-pytz
sudo apt-get install python3-flask
sudo apt-get install python3-requests
sudo apt-get install python3-paho-mqtt
sudo apt-get install python3-dnspython
sudo apt-get install dnsmasq

Set static IP

nano sudo nano /etc/dhcpcd.conf

Go to the bottom file and add IP information up to your network.

interface eth0
metric 300
static ip_address=192.168.0.40/24
static routers=192.168.0.1
static domain_name_servers=192.168.0.1

reboot!

Clone git-hub repo

git clone https://github.com/hash6iron/VevorWeatherbridge.git
cd weatherstation-ha-relay

2. Configure the environment

Edit the weatherstation.py file and set the following variables at the beginnig of the file.

• MQTT_HOST: Hostname or IP of your MQTT broker
• MQTT_PORT: Broker port (default 1883)
• MQTT_USER / MQTT_PASSWORD: Credentials if required
• DEVICE_ID: Unique identifier for the weather station device (default weather_station)
• DEVICE_NAME: Display name for the device in Home Assistant (default Weather Station)
• DEVICE_MANUFACTURER: (optional) Manufacturer name shown in Home Assistant (default VEVOR)
• DEVICE_MODEL: (optional) Model name (default 7-in-1 Weather Station)
• UNITS: metric (default) or imperial
• WU_FORWARD: Set to true to also forward data to Weather Underground (default false)
• WU_USERNAME / WU_PASSWORD: Credentials for Weather Underground (optional)

Example:

  TZ: Europe/Berlin
  MQTT_HOST: 192.168.1.100
  MQTT_PORT: 1883
  MQTT_USER: youruser
  MQTT_PASSWORD: yourpass
  DEVICE_ID: weather_station
  DEVICE_NAME: "Backyard Weather"
  DEVICE_MANUFACTURER: VEVOR
  DEVICE_MODEL: "7-in-1 Weather Station"
  # optional: "metric" (default) or "imperial"
  UNITS: metric
  # forward data to Weather Underground
  WU_FORWARD: "false"
  # credentials if forwarding
  WU_USERNAME: yourWUuser
  WU_PASSWORD: yourWUpass

3. Run

sudo nohup python weatherstation.py &

The service now listens on port 80 for requests to /weatherstation/updateweatherstation.php.

Network architecture and DNS redirection

You can redirect the weather station’s upload URL (rtupdate.wunderground.com) through aditional WiFi AP if your current WiFi AP or router doesn`t permit DNS redirection. See this proposal below with Raspberry Pi and additional WiFi Access Point that works fine and not need Pi-hole.

In the image below.

• Our weather script server on RaspBerry Pi - 192.168.2.100
• WAN Router - 192.168.2.1
• Weather router - 192.168.2.2

Set the following file with DNS redirection.

sudo nano /etc/dnsmasq.d/wunderground-redirect.conf

And include this line Note: IP 192.168.2.100 is the RaspberryPI Static IP

address=/wunderground.com/192.168.2.100

Save and close.

Now restart DNSMASQ.

sudo systemctl restart dnsmasq

Ensure that, /etc/resolv.conf is like below (nothing about 192.168.2.100 - our weather script server)

..
nameserver 192.168.2.1
..

Ensure that, /etc/hosts is like below (nothing about 192.168.2.100 - our weather script server)

..
127.0.1.1       WEATHER
..

Then you can see that Vevor talk with your server instead of wu server. You are ready for vevor bridge execution! (then step the following section below "Another one ...")

Endpoints

The service listens for GET requests at:

/weatherstation/updateweatherstation.php

With query parameters matching the WU format, e.g.:

http://<your-server-ip>/weatherstation/updateweatherstation.php?ID=XXXXX&PASSWORD=XXXXX&dateutc=xxxx-x-xx+xx:xx:xx&baromin=x&tempf=x&humidity=x&dewptf=x&rainin=x&dailyrainin=x&winddir=x&windspeedmph=x&windgustmph=x&UV=x&solarRadiation=x

---

How it Works

1. The weather station uploads data to this endpoint.
2. The service converts units to metric or keeps imperial values depending on UNITS.
3. Each value is published to Home Assistant via MQTT, auto-discovered as a sensor, and grouped under the configured device.
4. The endpoint returns success to acknowledge the update.

Home Assistant Sensor Entities

The following sensors are created or updated and will appear under the device specified by DEVICE_NAME:

Units in parentheses assume UNITS=metric; values switch to imperial when UNITS=imperial.

• sensor.weather_station_barometric_pressure (hPa)
• sensor.weather_station_temperature (°C)
• sensor.weather_station_humidity (%)
• sensor.weather_station_dew_point (°C)
• sensor.weather_station_rainfall (mm)
• sensor.weather_station_daily_rainfall (mm)
• sensor.weather_station_wind_direction (°)
• sensor.weather_station_wind_speed (km/h)
• sensor.weather_station_wind_gust_speed (km/h)
• sensor.weather_station_uv_index (index)
• sensor.weather_station_solar_radiation (W/m²)

You can use these entities directly in your Home Assistant dashboards or automations.
