Guess I should've taken a look at the script before I posted. It works exactly the way I needed out of the box. In fact, I was able to easily create an Azure web app and point Meteobridge to it for upload to WU every 5 minutes. It seems to work much better for WU playback than Bloomsky native integration with WU (I could never get WU time lapse video to work with the native integration). If anyone else is interested, I could modify the script to accept an API key as a querystring in the URL so anyone could use.
