Hello,
I will show you here how to display Météo France weather alert maps in Gladys
The maps come from: https://public-api.meteofrance.fr
The usefulness is debatable but it can be nice to have an overview 
The final result:
First you need to create an account and retrieve an API key on the site:
https://portail-api.meteofrance.fr/web/fr/
Next, you need to create the folders in Gladys for receiving the images and the script: (For this you need to connect via ssh to the Gladys host machine)
mkdir /var/lib/gladysassistant/img/meteofrance
mkdir /var/lib/gladysassistant/img/
mkdir /scripts
Then create the script
nano /scripts/meteofrancealertes.sh
#!/bin/bash
# Define the URL of the file to download
URL_TODAY="https://public-api.meteofrance.fr/public/DPVigilance/v1/vignettenationale-J/encours"
URL_TOMORROW="https://public-api.meteofrance.fr/public/DPVigilance/v1/vignettenationale-J1/encours"
# Define destination paths for files
DEST_TODAY="/var/lib/gladysassistant/img/meteofrance/today.png"
DEST_TOMORROW="/var/lib/gladysassistant/img/meteofrance/tomorrow.png"
# Maximum number of attempts
MAX_ATTEMPTS=5
# Function to download the file
download_file() {
wget --user-agent="Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36" -O "$1" "$2" --header="accept: */*" --header="apikey: apikey_aremplacer"
}
# Download the file for today
attempt=1
while [ $attempt -le $MAX_ATTEMPTS ]; do
echo "Tentative de téléchargement du fichier pour aujourd'hui ($attempt/$MAX_ATTEMPTS)..."
if download_file "$DEST_TODAY" "$URL_TODAY"; then
echo "Téléchargement du fichier pour aujourd'hui réussi."
break
else
echo "Échec du téléchargement du fichier pour aujourd'hui."
attempt=$((attempt + 1))
if [ $attempt -le $MAX_ATTEMPTS ]; then
echo "Nouvelle tentative dans 5 secondes..."
sleep 5
else
echo "Nombre maximal de tentatives atteint pour le fichier d'aujourd'hui. Arrêt du téléchargement."
fi
fi
done
# Download the file for tomorrow
attempt=1
while [ $attempt -le $MAX_ATTEMPTS ]; do
echo "Tentative de téléchargement du fichier pour demain ($attempt/$MAX_ATTEMPTS)..."
if download_file "$DEST_TOMORROW" "$URL_TOMORROW"; then
echo "Téléchargement du fichier pour demain réussi."
break
else
echo "Échec du téléchargement du fichier pour demain."
attempt=$((attempt + 1))
if [ $attempt -le $MAX_ATTEMPTS ]; then
echo "Nouvelle tentative dans 5 secondes..."
sleep 5
else
echo "Nombre maximal de tentatives atteint pour le fichier de demain. Arrêt du téléchargement."

done
Replace apikey_aremplacer with your API key that you obtained from the site https://public-api.meteofrance.fr
Create the crontab:
Values are retrieved every day at 16:10 and 06:10 because the Météo France site indicates:
crontab -e
10 16 * * * /scripts/meteofrancealertes.sh \u003e/dev/null 2\u003e\u00261
10 06 * * * /scripts/meteofrancealertes.sh \u003e/dev/null 2\u003e\u00261
Then create the 2 cameras like this:
You can then display them on the Gladys interface
I haven’t managed to get the white background but if you have a lead I’m open to suggestions 
If you have any questions/comments, feel free to let me know
Changelog to come:
- None (Your feedback welcome )
Edit 13/05/2024 :
