How to implement weather widget broadcast via DLNA on SMART TV?

Question

DLNA

Hello everyone, tell me how to implement one "Wishlist".
Given:
1. LG TV with DLNA support.
2. The desire to add a beautiful weather widget to the TV screen.
I would like to see the weather in the mode, if not realtime, then at least with an update every half an hour. I think to implement through a DLNA server, with support for widgets. I could not find an adequate server in terms of capabilities.
Tell me, how realistic is this possibility, or is it worth paying attention to other methods of transmission?
