I very much doubt you'll be able to do what you are hoping to do. You are essentially wanting your Smart TV to cause your browser to refresh automatically and I've not seen any that does it. I'm in the middle of a large project that will need to display reports on TVs across the organisation, so I'm going to rely upon Zero Clients attached to the TV and VM solution to handle what is displayed.
If you want something smaller and cheaper, a ChromeCast might allow you the flexibility you need. You can then load a plug in into Chrome to get your auto refresh.
