Overview
Controls LG TVs (webOS and earlier lines) from Control4 using infrared only, with no dependency on the TV's network. Intended for projects where the TV must not be controlled over IP.
- Discrete power on and off (not toggle), so the TV does not get out of sync.
- Direct selection of HDMI 1 to 4, TV (antenna) and AV inputs.
- Direct launch of the apps that have a key on the LG remote: Netflix, Prime Video, Disney+, Globoplay and LG Channels.
- 8 Quick Access connections to open YouTube or any other app or input, with no need for a remote key.
- Volume, mute, channels, number pad, navigation, Home, Back, Settings, Guide, color keys and transport controls.
- Continuous repeat of volume, channels and arrows while the button is held.
Requirements
- LG TV with an IR receiver (LG has used the same IR standard for years, including OLED, QNED and NanoCell).
- An IR emitter from the Control4 controller (or an IR blaster) placed over the TV's IR receiver.
Installation in Composer
- Add the 4Drivers LG TV Generic driver to the project.
- Fill in the license key in Chave (or leave "Trial" while testing).
- In Connections, bind the driver's IR Sensor connection to the controller IR output where the TV emitter is attached.
- Bind the video sources to the driver inputs (HDMI 1 to HDMI 4, TV ANT, INPUT AV 1) according to the physical wiring.
- For apps, add the Control4 universal mini drivers (Netflix, Globoplay, etc.) and bind each one to the matching MiniApp connection (see the table below).
- Test power on, power off and input switching. If the TV is slow to accept the first command after powering on, increase Power On Delay-Milliseconds.
Streaming apps
The driver opens apps in two ways: through the app keys of the LG remote and through the TV Quick Access feature. In both cases, when the app is selected in Control4, the driver first takes the TV to the home screen (Home Before App property) and then opens the app.
1. Apps with a key on the LG remote
Just bind the app's universal mini driver to the matching connection:
| Connection | App |
|---|---|
| MiniApp 0 - GLOBOPLAY | Globoplay |
| MiniApp 1 - NETFLIX | Netflix |
| MiniApp 3 - PRIME VIDEO | Prime Video |
| MiniApp 5 - DISNEY+ | Disney+ |
| MiniApp 6 - LG CHANNELS | LG Channels |
2. Quick Access 1 to 8 (any app or input)
For apps with no key on the LG remote, such as YouTube, Spotify, Apple TV and Max (or the ones that did not work above), the driver has 8 connections: Quick Access 1 to Quick Access 8.
How it works: on LG TVs, each remote number from 1 to 8, when held down, opens the app (or input) assigned to it on the TV itself. When the user selects the source bound to the Quick Access N connection, the driver sends number N held down, and the TV opens the app assigned to that number.
| Connection | The driver sends | The TV opens |
|---|---|---|
| Quick Access 1 | Number 1 held down | The app assigned to number 1 on the TV |
| Quick Access 2 | Number 2 held down | The app assigned to number 2 on the TV |
| Quick Access 3 | Number 3 held down | The app assigned to number 3 on the TV |
| Quick Access 4 | Number 4 held down | The app assigned to number 4 on the TV |
| Quick Access 5 | Number 5 held down | The app assigned to number 5 on the TV |
| Quick Access 6 | Number 6 held down | The app assigned to number 6 on the TV |
| Quick Access 7 | Number 7 held down | The app assigned to number 7 on the TV |
| Quick Access 8 | Number 8 held down | The app assigned to number 8 on the TV |
Quick Access setup (once per app)
The TV's original remote is not needed. Everything is done from Control4:
- Pick a free number from 1 to 8 for the app (e.g. YouTube = 1).
- Open the app on the TV using the TV remote in Control4 (Home, arrows and OK).
- With the app open, run the Long Press action for the chosen number in Composer (driver Actions tab; e.g. Long Press 1).
- The TV asks whether to assign the current app to that number: confirm with OK from Control4.
- Add the app's universal mini driver and bind it to the Quick Access connection with the same number (e.g. Quick Access 1).
- Test by selecting the app in Control4. Repeat for the other apps, up to 8.
It also works with the original remote: with the app open, hold the number and confirm.
- Write down in the project which number holds which app.
- The assignment is stored on the TV. If the TV is factory reset or replaced, redo the setup.
- A short press on the number still works normally as a channel digit.
- Quick Access is available on recent LG webOS TVs. On older models without this feature, these connections do not work.
Properties
| Property | Description |
|---|---|
| Debug Mode | Print = logs activity (turns itself off after 60 minutes). |
| Chave | 4Drivers license key for this driver. |
| Validacao | Read only: license status (5-day trial, validated, blocked). |
| Power On Delay-Milliseconds | Time the TV takes to power on. Commands sent during this time are queued and sent afterwards. Default 4000 (4 s). |
| Command Delay-Milliseconds | Interval between consecutive commands (e.g. channel digits). Increase it if the TV misses commands. |
| Press-Release Command Delay-Milliseconds | Repeat interval while a button is held (volume, channels, arrows). If the command keeps going after the button is released, increase this value. |
| Repeat Count | How many times each IR code is transmitted. Increase it if the emitter is far or poorly placed; decrease it if the TV executes a command twice. |
| Home Before App | Yes = when an app is selected, the driver first sends the TV to the home screen (Smart TV) and only then opens the app. Required on models that ignore the app key while on an HDMI input. |
| App Launch Delay-Milliseconds | Time between going to the home screen and the app key. Default 1500 (1.5 s). Increase it if the TV opens the home screen but not the app. |
| Long Press Time-Milliseconds | How long the number is "held" for the Quick Access connections and the Long Press actions. Default 2000 (2 s). |
| Driver Version | Installed driver version. |
| Last Server Version / Server Version Notes | Latest version available from 4Drivers and its notes. |
Programming (Composer)
The Info button on Control4 screens and remotes opens the TV home screen.
In the driver Actions tab, the Long Press 1 to Long Press 8 actions send the held number, to assign and test Quick Access.
Besides the standard TV commands, the driver has an Emit IR Code command that sends any key from the list (e.g. Home, Q.Menu, Exit, Aspect Ratio, AV Mode, Simplink, captions, color keys). Useful for macros and custom buttons.
Limitations
- IR is one-way: Control4 does not receive the TV state (power, input, volume). If the TV is operated with its original remote, the state shown in Control4 may differ.
- No discrete volume (exact level): volume up and down only.
- The Quick Access connections depend on the assignment made on the TV (available on recent webOS TVs).
Troubleshooting
| Symptom | What to check |
|---|---|
| TV does not respond at all | Emitter placement over the TV's IR receiver, IR Sensor connection bound to the right port, and a valid license (Validacao). |
| Powers on but does not switch input | The TV was still starting: increase Power On Delay-Milliseconds or enable Quick Start on the TV. |
| Commands lost in a sequence | Increase Command Delay-Milliseconds. |
| Command executed twice | Decrease Repeat Count. |
| Volume keeps going after release | Increase Press-Release Command Delay-Milliseconds. |
| Opens the home screen but not the app | Increase App Launch Delay-Milliseconds. |
| Quick Access does not open the app | Check that the connection number matches the number assigned on the TV. If the TV just types the digit, increase Long Press Time-Milliseconds. |
| App does not open | The TV model/region may not have that app key, or the app is not installed. |
For support, set Debug Mode = Print, reproduce the problem and send the log to 4Drivers (contato@4drivers.com.br).
