This Powershell script changes your desktop wallpaper based on the weather.

This is a re-implementation of https://github.com/yangman946/WallPaperChanger in pure Powershell.

• Powershell 7.2 or newer
• Your own api key for openweather: https://openweathermap.org/api
  • This api key must be in a file at: src/config/config.properties with a single line like: app.api-key=<YOUR-API-KEY>
  • You will be prompted for your api key the first time the application is run and the file will be created automatically

Note: This version does not support the original overlay of current time, weather forecast etc. Instead an application like Rainmeter can be used to achieve this effect.

• Run file from powershell or set up a scheduler to run it periodically

1. In the windows task scheduler create a new task, give it a suitable name.
2. Under Triggers add the event you want to trigger the script (e.g. logon, unlock or hourly). Note that is you want an hourly run that this is set up as daily at a given time, recur every 1 days and in the advanced settings below repeat the task every 1 hour
3. in Actions set the program to the powershell.exe you want to execute. Note that there can be multiple versions of powershell in a windows system. Try to look for this path: "C:\Program Files\PowerShell\7\pwsh.exe"
4. In Add Arguments add: -File .\Wallpaper-Changer.ps1 and in the Start in field insert the path to the directory where the Wallpaper-Changer.ps1 script is located.

Currently, the Wallpaper-Changer.ps1 script supports the following weather states for both day and night:

• Clear
• Mist (cloudy)
• Rain
• Thunder
• Snow

You will find separate pairs of folders for each weather condition (day and night). These folders contain jpeg images (3936x2624 pixels) each labeled from 1 to the number of images in the folder. You can add/remove any image you want to in the existing folders.
