| Updating applications | Weekly | Average (new features) | Average |
| TTX databases | Daily | Low (channel lists) | Low |
| Safety certificates | As it comes out | Critical (access to services) | High |
It's worth noting that some manufacturers may discontinue support for older models, ceasing to release updates. In this case, Wi-Fi will no longer provide new features, but will ensure the functionality of existing services.
Smart home management and device integration
TV with support Smart TV It often becomes the visual center of a smart home system. Via Wi-Fi, it can stream video from surveillance cameras, display notifications from smart doorbells, or display weather and exchange rates on the screensaver. This turns the screen into an information panel for the entire apartment.
Integration with voice assistants such as Alice, Siri or Google Assistant, is also impossible without a network. You can use your voice to ask the TV to turn on the lights in the room, change the thermostat, or show the camera at the front door. All these commands are processed in the cloud and transmitted to the device via the internet.
- 🏠 Display images from IP surveillance cameras in real time.
- 🔔 Receive push notifications from smart sensors and doorbells.
- 🗣️ Voice control of smart home scenarios via built-in microphones.
- 🌡️ Control of climate control and lighting via TV interface.
Protocol compatibility
Not all TVs support all smart home protocols. The most common are Matter, Zigbee (via hubs), and proprietary systems. Before purchasing a smart bulb, check if there's an app for it on your TV platform.
However, it's important to keep in mind that the network load increases when connecting multiple devices. If you have more than 20 smart home devices in your home, a standard router may not be able to handle the data flow, and the TV will start to lag when switching between windows.
⚠️ Please note: Smart home app interfaces on TVs may change after updates. Always check the latest instructions in the "Support" section of your device manufacturer's website.
Organizing your home media library (DLNA and NAS)
One of the most useful, yet often overlooked, features is access to local files through DLNA or SMBIf you have a movie collection on your computer or network-attached storage (NAS), you can play them on your TV without transferring the files to a flash drive. The TV sees your computer folders as network resources and opens them like regular menus.
To set up such a system, the computer and TV must be connected to the same router. Transmission quality depends on the Wi-Fi speed, especially if you plan to watch large files with a bitrate above 50 Mbps. In this case, the wireless connection must be stable and uninterrupted.
There are special media library applications such as Plex, Kodi or Jellyfin, which transform viewing into a true cinematic experience with beautiful covers and descriptions. These apps rely entirely on a network connection to download metadata about films and actors.
Typical path structure for SMB:smb://192.168.1.105/Movies/Action
smb://192.168.1.105/Movies/Comedy
When setting up access, it's important to correctly specify access rights to folders on the computer; otherwise, the TV won't be able to read the file list or play videos. It's often necessary to allow guest access or create a separate user for the media server.
Gaming Features and Cloud Gaming
