Hello,
ThingWorx mashups are just normal HTML pages, so just open the one you need and copy the URL into your digital signage configuration. You’d need to handle authentication though:
1. Create an App Key for a user that has sufficient permissions to view that mashup. You can start with Administrator for a proof-of-concept.
2. Enable “Allow Application key as URL” in the Platform Subsystem configuration.
3. Add &appKey=xxxxxxx to your mashup URL. This should log you in without asking for credentials.
Of course this assumes that your digital signage installation is connected to Internet. Otherwise you’re out of luck.
