Just a small update to this one:
I am running WeatherCat on my Mac mini.
Then I installed an FTP Server on my mini (this one:
FTPServer). Next step was creating a new folder that WeatherCat can use as "SavePathFolder". Now WeatherCat processes the files within the "CustomWebFolder" to the (new) "SavePathFolder" and in the preferences I told WC to upload to the FTP Server folder I ceated with the app linked above. Now how to bring all the files up to my webhost using FTPS or SFTP? Three other apps helped me doing this: Automator,
Transmit and
Lingon. With Automator I created two programms that are executing "look for files within the finder" then "open an FTPS connection with Transmit", ftp the files and close the connection. The last step is using Lingon to create two LaunchDaemon scripts (one that is executed every 15 mins for the app that uploads all the files and webcam pictures that are found in the FTP Server folder, the other one executes every 1 min for the app that uploads the txt file used by SteelSeriesGauges. The nice thing is that all is running on one PC - no Raspi or something else needed.
Any Questions?
Yes, a bit complicated but doing what I want so far that I am back in business with WeaterCat and my website.
