How to Control an LG OLED from iPhone, iPad, Mac or Android on Your Local Network

The short answer

To control an LG OLED locally, connect the TV and your iPhone, iPad, Mac or Android device to the same home network, allow the controller app to access nearby devices, and approve the TV’s pairing prompt. The router must permit device-to-device traffic. A guest Wi-Fi network may provide internet access while blocking the discovery packets a local remote needs.

AirPlay, LG ThinQ and a third-party local remote are different paths. AirPlay sends media or mirrors a screen. ThinQ combines local setup with an LG account. OLED Control talks to compatible LG webOS TVs over your network. Decide which job you are solving before changing TV settings.

Choose the right control path

No app can repair network isolation. If the device cannot reach the TV, the first task is network setup, not remote-button configuration.

iPhone and iPad: allow Local Network access

Since iOS and iPadOS 14, apps that browse for devices on your home network must ask for Local Network permission. Apple exposes the choice under Settings → Privacy & Security → Local Network. Turn access on for the controller you intend to use.

This permission is narrower than general internet access. An app can load a website while being unable to discover your TV. It is also separate from AirPlay: Apple notes that system services such as AirPlay can continue to use the local network even when a particular app is denied direct browsing access.

After granting permission, fully reopen the app and repeat discovery with the TV awake. If the TV shows a pairing dialog, approve only the device you recognize.

Mac: check the app and the network, not only Wi-Fi

Recent macOS versions also expose local-network access in System Settings → Privacy & Security → Local Network. If a Mac controller previously worked and then stopped after an OS update or a denied prompt, check that setting before removing the TV.

For AirPlay screen mirroring, LG instructs users to place the Mac and TV on the same Wi-Fi network, open Control Center, choose Screen Mirroring, select the TV, and enter the code shown on the TV when requested. AirPlay availability depends on the LG model, region and installed software; it should not be used as proof that every local-control protocol is available.

Ethernet on the Mac or TV is fine when the router bridges wired and wireless clients into the same local network. “Same Wi-Fi” in a quick-start guide usually means same reachable LAN, not that every device must use the same radio.

Android: nearby-device and network permissions

Android permission names vary by OS release and phone vendor. A control app may request Nearby devices/Bluetooth for nearby discovery and location-related access when scanning or configuring Wi-Fi devices. Review the app under Settings → Apps → [app] → Permissions and grant only the access explained by the setup flow.

Battery optimization can suspend an app in the background, but it normally does not explain a TV that is missing during an active foreground scan. Prove same-network discovery first. Then investigate background reliability if scheduled or long-running control is the actual problem.

A clean local pairing workflow

1. Turn on the TV and wait until webOS is responsive.
2. Confirm the TV’s network status and note the network name.
3. Put the phone, tablet or computer on the same normal home network.
4. Disable VPN software for the pairing test.
5. Open the controller and allow its local-network request.
6. Select the correct TV and approve the code or pairing prompt on screen.
7. Test a harmless command such as volume or navigation.
8. Turn the TV off and test standby wake separately.

Keep the last step separate because wake-up depends on whether the network interface remains available in standby. A controller that works perfectly while the TV is on is already paired correctly.

Why guest Wi-Fi and some mesh setups fail

Guest networks commonly isolate clients so visitors can reach the internet but not printers, storage devices or TVs. Some mesh and managed networks can place devices in separate VLANs even when their SSID labels match. Local discovery may also rely on multicast traffic that a network administrator can filter.

For diagnosis, place both devices on the main SSID and temporarily remove VPN or security software that changes local routing. If the TV then appears, restore each network feature one at a time. Do not weaken the router permanently merely to make discovery convenient.

AirPlay is not a universal remote protocol

AirPlay is excellent for sending video, audio or a mirrored Apple display to a supported LG TV. It does not expose every webOS setting or reproduce every Magic Remote action. Conversely, a local-control app does not automatically mirror protected video or become an AirPlay receiver.

LG’s current guidance says compatible AirPlay screen sharing requires the Mac and TV on the same Wi-Fi and may ask for a code. Support began on selected LG generations and was expanded by software updates, so verify the full model rather than assuming that “OLED” alone guarantees it.

Standby, power-on and Quick Start+

Power-off is an ordinary command while the TV is reachable. Power-on requires the TV to listen for a supported wake signal in standby. LG documents ThinQ power-on for webOS 3.5 and later, with Wi-Fi for iPhone and Wi-Fi or Bluetooth options on supported Android setups. Older versions may offer only power-off.

Quick Start+, Wake-on-LAN, and TV On With Mobile can interact, but they are not synonyms. Use the focused remote power guide before toggling standby behavior.

Security and privacy basics

• Approve pairing prompts only while you are adding a controller.
• Keep the TV and router software current through their normal update channels.
• Do not expose webOS control ports directly to the public internet.
• Prefer a trusted private LAN over hotel, dormitory or captive-portal Wi-Fi.
• Revoke an app’s local-network permission when you no longer use it.

OLED Control remains anonymous at the TV pairing layer and is designed for local workflows, but the operating system still decides whether the app can reach nearby devices. For a guided first connection, continue with OLED Control first setup or troubleshoot connection issues.
