First, you'll need to make sure that Apache is configured to use HTTPS. To do this, you'll need to generate an SSL certificate and configure Apache to use it. There are many tutorials available online that can guide you through this process, such as this one from DigitalOcean:
https://www.digitalocean.com/community/tutorials/how-to-create-a-self-signed-ssl-certificate-for-apache-in-ubuntu-18-04Once you have configured Apache for HTTPS, you'll need to create a directory within your web root where you can receive the data being sent by your WS-5000. To do this, open Terminal on your Mac and navigate to the web root directory by typing cd /Library/WebServer/Documents. Then, create a new directory to receive the data by typing sudo mkdir awdata.
Next, you'll need to give Apache permission to write to this directory by typing sudo chown -R _www:wheel awdata and sudo chmod -R 775 awdata.
Finally, you'll need to configure Ambient Weather to post the data to the correct URL using HTTPS. The URL should be in the format https://<your-mac-ip-address>/awdata/, where <your-mac-ip-address> is the local IP address of your Mac.
I hope this helps get you started with configuring Apache for use with Ambient Weather! Let me know if you have any further questions or issues.
