Allsky Weather

A script that outputs local weather information to a text file, for use with an Allsky camera to display local weather conditions in Allsky images.

This script uses the OpenWeatherMap API - a free API key needs to be generated in order to use this script.

Example usage

On the machine or device where you need to use this script, do the following:

1. Download the contents of this repository into a new folder
2. Install Node.js
3. Run npm install to install the required packages
4. Test the script by running the command below, or add a Cron job or scheduled task that calls the script at a set interval, in order to generate the text file with fresh data:

node index.js --output=/home/pi/allskyweather/weather.txt --key=YOUR_API_KEY --city=London --region=Europe/London

For example, I use this Cron entry for running the script every even minute (every two minutes) on a Raspberry Pi (see the documentation here for how to set this up on Raspberry Pi):

*/2 * * * * /usr/bin/node /home/pi/allskyweather/index.js --output=/home/pi/allskyweather/weather.txt --key=YOUR_API_KEY --city=London --region=Europe/London

Arguments

• --output - The full path where to generate the text file
• --key - Your API key for the OpenWeatherMap API service (please note: API keys take a few minutes before they become active after creation)
• --city - The location you want to generate weather information
• --region - This is the timezone region for generating the correct local sunrise and sunset times. For valid values, refer to the date-fns-tz package

Adding the text to Allsky images

Update the settings_ZWO.json file in your Allsky folder by adding the location of the extratext file:

"extratext":"/home/pi/allskyweather/weather.txt"
