Your initial post and topic title refer to “Smart TV app”, but there are a number of smart TV platforms or operating systems used by different manufacturers: Google TV, Amazon Fire TV, Roku TV, LG webOS, etc. Knowing what you’re using and where you want to view your Cams is important for knowing where to direct you for other information and for suggesting potential solutions. For instance, knowing that you’re using a Samsung TV, we could suggest this existing Wishlist topic:
As with any Wishlist topic, you can visit that one to click or tap the Vote button above the initial post and share your ideas and use cases in the comments to show your support for the product and feature request/suggestions that are important to you.
If you used a Samsung Galaxy phone, then I’d suggest something like Samsung DeX to connect your phone to the TV and run the Wyze app through that display, like @ssummerlin does, but I don’t know if any equivalent exists for iOS. Since I don’t use iOS, I’m probably the last person you want attempting a step-by-step solution for this.
