I have a webcam on a raspberry that sents pictures in a dropbox file. Is it possible to get these fotos from dropbox and show them on openHAB UI ?
There was a thread maybe a year ago on this topic. The end answer ended up being that you need to set up a link to the image files in your webapps folder, use the Image sitemap tag with a refresh value for how often to refresh the image, and a script of some sort to copy or symlink the most recent image to the name of whatever the name is included on your sitemap. You would need to have your dropbox folder on your machine using whatever Dropbox app is appropriate for your machine. There is no way I know of to pull files straight from Dropbox from openHAB.
