Setting up http proxy

As the stations FW cannot handle url with /path we need a little help with http proxy. You can use your already set proxy server or setup a new one.
If you are setting new proxy there are two approaches - configuring a new server on your machine or use Home Assistants add-ons.

Setup a new http proxy server using nginx

Follow installation guide for your system or build version for your system - nginx download page

  sudo apt-get install nginx  
  
  sudo wget -P /etc/nginx/sites-available https://github.com/schizza/WeatherStation-SWS12500/blob/f7be558bbb5945ad6eba2f54a6fd18767f5cc342/weatherstation.nginx.conf 

  sudo ln -s /etc/nginx/sites-available/weatherstation.nginx.conf /ect/nginx/sites-enabled/weatherstation

  sudo systemctl restart nginx

Setup Nginx Proxy Manager with Home Assistant's addon

1. In Home Assistant go to Addons and install Nginx Proxy Manager
   you need MariaDB installed (in HA addons) to run Proxy Manager correctly

2. In configuration tab set appropriate ports for you configuration
   

HTTP/SSL Entrance port: you need to set this value form 443 to something else because port 443 will be in use
HTTP Entrance port: this is your port for communicating with station throught your proxy server
NGinx Proxy Manager Admin web interface: port of administration web page

Now you can start your Proxy Manager. First start will take a while - be patient

3. While Nginx Proxy Manager is running, go to administraion page.

First login
user: [email protected]
password: changeme

4. Create a new proxy host
   

Save and you are done with http proxy!

Configure station in AP mode

Now you need to configure your station in AP mode to send data to your local HA installation.

• hold WiFi button on the back of station for 6 seconds until AP will flash on display.
• select your station from available AP on your computer
• connect to stations setup page: http://192.168.1.1 from your browser
• in the third URL section fill in address to your local HA installation

URL: IP address of your http proxy set in HA or server Station ID: not needed. Might be filled in for security reasons
Station Key: not needed. Might be filled in for security reasons

you can change /weatherstation to whatever you want, but you have to change NR configuration appropriately.

Node-Red flow

To receive data from your station you need to add Node-Red flow

• Download NR-flow.json and import it to Node-Red

The flow implements MQTT discovery so the sensor will show in Home assistant automatically under name: sencorsws12500

Send meteo data to windy.com

First of all you need to create station on windy.com: Windy stations

After registering your station to windy.com you will get API key which will be used in NR flow.

• download Windy-function.json and add this function with http request to NR
• make sure to update lon, lat, elevation, tempheight, windheight in windy function to match your data

lat: your latitude
lon: your longitude
elevation: your elevation
tempheight: sensor elevation above ground level
windheight: sensor elevation above ground level

• connect Windy function to Data reciever

• configure http request with your API key from Windy Stations

And you are done. Windy.com will now show you data.
