Is there any other way to deploy IoT data from Thingworx to HoloLens?
Or, can Thingworx be accessed remotely using Microsoft HoloLens?
if you really want to open a Mashup from Thingworx Foundation (NOT studio!) you can open a webpage in Hololens.
If you want to open an experience in hololens using IoT Data - giri has made the correct explanation.
You can display and also use IoT data in any end device.
