Device Configuration

In order to allow the driver to turn on the TV from sleep mode, ensure that Wake on Wireless Network and Wake-on-LAN are enabled. These settings can be found in the Network section (Home > Settings > Network).

RTI Configuration

Please ensure that your RTI processor’s time is set to match your TVs. The authentication process requires that the correct UNIX timestamp is sent to the TV if attempting first-time authentication. This means that the correct Time Zone should also be set in Integration Designer (System Properties > Clock) before the system is sent to the processor. If you have set the Time Zone to the same as the computer running Integration Designer and have ticked “Set clock from PC when downloading” then the RTI processor will be able to successfully connect as long as the PC can. If this is incorrectly configured, then connection will not be possible via first-time authentication which may be needed if the refresh and access tokens both expire, which can take place if 21 days pass without a connection.

Driver Configuration

System Configuration

• Number of TVs: The number of Loewe TVs that are being connected to the driver.

• Which TV to Pair: The TV which the installer is looking to pair. This allows installers to pair devices in any order they choose. There is one selection available for each TV in the System Configuration, labelled by its friendly name and its IP address.

TV Config (one section per TV)

• IP Address: The IP Address of the TV, this can be found by turning on the TV, navigating to the IP Settings page (Home > Settings > Network > Network Configuration > IP Settings). Copy the displayed IP Address into Integration Designer to allow connection with the TV.

• TV Brand: The brand of the TV, required for authentication and connection with the TV. Options are Loewe or WeByLoewe. To see whether the TV is a part of the We. series, navigate to the Version Information (Home > Settings > Support > System Info) and check the model name.

• TV Friendly Name: The friendly name of the TV used by the installer to differentiate between TVs.

Once this information has been entered, press Pair Device in order to connect to the TV specified in the Which TV to Pair field.

TV Input Names (one section per TV)

• Friendly Name (one per Input): The friendly name of the input source used by the installer to differentiate between Inputs.

Once all names are set (Input and TV), the driver will generate the appropriate system functions, function parameters, variables, tags, and Integration Designer sources for each TV that you can add from the driver to the source list to assist in auto-programming.

Apex Actions:

• Pair Device: This creates the first connection between the device and the TV. This allows for the discovery of sources, as well as retrieval of tokens for future connections. The installer will first be prompted by a message box to ensure that the TV is turned on before any connection attempt is made. If this is the first connection, a message box will appear on Integration Designer which will tell the installer to expect a pop-up on the selected TV when ‘ok’ is pressed on the Integration Designer message box. This pop-up requests remote control over the TV, which is required for the driver to control the TV. If the TV has already been connected and the connection tokens haven’t expired, then a connection will be made, and the list of inputs will be updated if they have changed. When connection succeeds, another entry in the TV Config will also appear, which will display a non-changeable field corresponding to the Model Name of the TV to the installer.

Driver Functions

For each TV, there are the following functions:

Power:

Turn on or off the TV. This either sends the Power On/Power Off remote press, if the TV is awake or in fake sleep mode, or runs the Wake-on-Lan process, if the TV is in deep sleep mode.

Parameters:

• State – The state to which the TV is being set, either On, Off, or Toggle.

Volume:

Change the volume of the TV, used for increasing/decreasing the volume by 1, or to mute the TV. Volume ramping is also handled within the driver, allowing for a user to hold a volume up or down button to ramp the volume continuously, which accelerates after holding for a short period of time. In order to enable this, the installer must set “Sustain” to “Yes” and then set the “Delay between repeats” to a desired level. These are found by expanding the option of the Volume function by clicking the plus sign next to the word command in Integration Designer. The recommended value for “Delay between repeats” is 200 and it must be under 300 to allow for ramping to work as intended.

Parameters:

• State – How the volume is being manipulated, either Up, Down, or Mute Toggle.

Set Volume:

Set the volume of the TV to a specific level. This function is ideal for integrating with a volume slider within Integration Designer.

Parameters:

• Level – The desired Volume Level of the TV, an integer that can range from 0 to 100.

Set Input:

Set the Input Source of the TV, used for switching to, for example, an HDMI source. If the TV is off when an input source is selected, then the TV will power on and then switch to the desired source as soon as a connection to the TV is made.

Parameters:

• Input – The desired Input Source of the TV, one choice for each source associated with the TV, identified via the friendly names entered by the installer for each source in the Driver Properties.

Send Key:

Send a key press to the TV, which is equivalent to pressing a button on a remote control.

Parameters:

• Button – The key press to be sent to the TV. The choices for the button press are as follows:

Power: Power On, Power Off, and Power Toggle. Note that these key presses do not trigger a Wake-on-Lan if the TV is off. This means that if the TV is in deep sleep, then the TV will not be turned on via the Toggle or on commands. Use the Power function in order to utilise Wake-on-Lan.

Digits: The digits keys from 0-9.

Volume: Volume Up, Down, and Mute. Note that the Volume Up and Down presses display the current volume on first press and then adjust it on any subsequent presses. This is different to the Volume function, which triggers an increase or decrease of volume immediately.

Channel: Channel Up, Down, and Previous.

Navigation: Directional Pad buttons, as well as Ok, Back, and Exit.

Colour: Red, Yellow, Green, and Blue.

Playback: Play/Pause, Play, Pause, Stop, Skip Forward, Skip Backward, Record, PVR, Timeshift.

Text/Language: Teletext, Subtitles, Audio/Language, Audio Only.

Source: TV Mode, HDMI 1-4, Media, My Apps. Note that these keys and labels are fixed, they aren’t generated in the same way that the Input Function options are, meaning that some of these key presses may not behave as expected if, for example, the TV doesn’t support 4 HDMI sources. Also note that these button presses don’t trigger a Wake-on-Lan if the TV is in deep sleep mode. Use the Set Input function to utilise Wake-on-Lan when an input is selected.

Open App:

Open an App on the TV. If the TV is off when an app is selected, then the TV will power on and open the selected app as soon as a connection to the TV is made.

Parameters:

• App – The App to be opened on the TV. The apps that can be opened are as follows: Netflix, YouTube, Amazon Prime Video, Disney+, Rakuten TV, Apple TV+, DAZN, ViaPlay, Deezer, Freeview Play.

Send Keyboard:

Send a key press that is equivalent to a key that would be found on a keyboard. Useful for entering strings into search bars within Apps. Note that all letters are sent as uppercase and this driver does not support the use of a Shift or Caps Lock key.

Parameters:

• Key – The key press to be sent to the TV. The choices for this are as follows: The uppercase letters A-Z, the numbers 0-9, and the special characters ‘@’, ‘\’, ‘/’, ‘.’, ‘,’, Backspace, Enter, and Space.

Display Message:

Display a message on the TV, a message box will pop up on the screen with the desired message.

Parameters:

• Message – A string that corresponds to the message to be displayed on the TV screen.

Open URL:

Open a website on the TV. This will open the browser app to the desired URL and allow control using the directional pad to move the cursor on screen.

Parameters:

• URL – a string that corresponds to the URL to be opened on the TV.

Driver Variables

Reports whether the TV is currently connected to the driver. Note that this will be set to false if the TV is in deep sleep mode, though triggering a Wake-on-Lan via the Power command will still turn the TV on and initiate a connection with the driver.

• Type: Boolean

Power

Reports whether the TV is currently on. Both deep sleep and fake sleep (which is when the TV appears to be off but is still recording) are treated as off.

• Type: Boolean

Volume

Reports the current volume level of the TV. Values range from 0 to 100

• Type: Integer

Mute

Reports whether the TV is currently muted.

• Type: Boolean

Input

Reports the current input being displayed on the TV.

Input (V)

• Variable usage: The current input of the TV, expressed as a string, matching the friendly name set by the installer.

Additionally, a tag is created for each Input friendly name. This means that if an installer set a friendly name for an Input to, for example, ‘HDMI 1’, then an ‘HDMI 1’ tag would be added. These function tags set the TV’s current source to the selected input. This function also triggers a Wake-on-Lan for the TV if it is in deep sleep mode.

Exceptions

• When using the keyboard buttons, the capitalisation of the letters is unpredictable despite the driver sending all characters as uppercase. This should have no impact on the use of the keyboard since adjusting the case of the letters is not possible anyway. For case-sensitive entries, such as passwords, use the on-screen keyboard controlled by the directional pad key commands.

• On occasion, we have noticed that the keyboard does not work as intended. Despite the correct command being sent out from the Driver, key presses don’t always register on screen. In these cases, the on-screen keyboard can still be controlled via the directional pad. Restarting the app often fixes this problem as can restarting the TV. Furthermore, not all apps support keyboard entry in text entry boxes. In these cases, the only option is to use the on-screen keyboard using the directional pad.

Troubleshooting

If the driver cannot control the unit, confirm the following:

• The TV is connected to the same network as the RTI processor, either via Wi-Fi or Ethernet.

• The correct IP address is defined in the RTI driver properties for the TV.

If a connection still can’t be made, try power cycling the TV in question.
