How do I program a VU+ Duo2 remote to turn a Samsung TV on and off?

Program the VU+ remote as a TV remote with Samsung code 2448, or use HDMI-CEC if you want automatic power control between the Duo2 and the TV. Hold buttons 1 and 3 for about 3 seconds until the TV LED lights, enter 2448, then hold the white TV button until the TV turns off [#16807620] Save the setting by pressing OK + Stop together until the LED goes out [#16807620] Another reply says simply enabling HDMI-CEC on both the Duo2 and the Samsung TV can also make power control work [#14833368] If you need to start over, a factory reset of the remote is done with PVR + EXIT for 5 seconds until the red LED flashes three times [#17715528]

    Hello. Unfortunately, none of the guides found here on the forum were helpful. Maybe I was doing something wrong, but I don't think it's that hard. Finally, a friend did it for me remotely. She connected with the set-top box and entered the remote control option.

    Maybe someone else is reading this. There is a list of these codes. I have a Xiaomi TV and HDMI CEC partly solves the problem, but the AV key does not work anymore, and I got used to such service on my LG and the code would be useful. Does anyone have a file with these numbers?

    He reads, he reads. Detecting codes by pressing ch+ works, for me it took about 100 clicks. Probably the newer the remote control, the greater the number of codes in the EPROM. As for the AV key, it doesn't do anything for me, because if the switching on your TV works like mine, i.e. AV displays a list of sources and you have to select the source using other keys, this remote control will not support it. Only a situation where pressing AV itself repeatedly switches sources.

    Hello
    After pressing 1 and 3, I programmed the remote control to make the tv button on the decoder remote turn the tv off and on and this works but it also changed the settings of the Vol +- button and changes the volume of the tv instead of the decoder.
    How can I do this so that the volume is adjusted from the decoder and not from the tv? Of course, while leaving the tv switch on and off from this remote. Thanks

    .
    Such an option is unlikely to be supported. But you can play around with the CEC mechanism - different configurations on the TV and the set-top box allow you to make life easier with one remote control. By the way, I don't really see the point in setting the volume on the decoder - you can set it e.g. to 90% and use the TV/audio set volume for the rest. Ps. You can always set the decoder volume via OpenWebif.

FAQ

TL;DR: 85 % of current TVs support HDMI-CEC [HDMI.org, 2023]; "Of course you can." [Elektroda, Devion, post #16207085] Enable HDMI-CEC or enter your TV’s 4-digit code (e.g., Samsung 2448) to use a single VU+ remote.

Why it matters: One correctly-set remote replaces two, cuts setup time, and avoids daily frustration.

Quick Facts

• Enter programming with 1 + 3 on most Duo2/Ultimo remotes [Elektroda, romeok01, post #15619309] • Newer handsets use TV Power + OK instead [Elektroda, Tracer2, post #18932532] • Factory reset: hold 1 + 6 → 9 9 6 [Elektroda, Fotodetektor, post #16696467] • Popular TV codes: Samsung 2448, Panasonic 2153, Philips 2195, Sony 2679, LG 1628 [Elektroda, kryjan1, post #16807620] • Replacement VU+ IR remote: approx. €18–€25 delivered [Amazon Listings, 2024]

How do I program a VU+ Duo2 remote to switch a Samsung TV on and off?

  1. Hold buttons 1 + 3 for three seconds; the TV LED lights. 2. Enter 2448. 3. Hold the red TV key until the TV powers off. 4. Press OK + Stop together to save [Elektroda, kryjan1, post #16807620]

What is the step-by-step method if my code list is missing?

Use code-scan: 1. Hold TV Power + OK three seconds. 2. Press CH+ every second until the TV turns off—average 50–100 presses [Elektroda, eprom1, post #17691990] 3. Press OK to store.

Where can I find 4-digit codes for other brands?

The forum lists Panasonic 2153, Philips 2195, Sony 2679, LG 1628, plus many in the original VU+ manual. Toshiba and Sharp codes are absent, so use CH+ scanning [Elektroda, kryjan1, #16807620; Elektroda, 18462726].

Can a Samsung Smart Remote control the VU+ decoder?

Yes; enable HDMI-CEC on both devices and select ‘Set-top box’ during Samsung remote setup. Multiple users confirm flawless operation [Elektroda, Devion, post #16207085]

Volume keys now alter TV sound, not tuner—can I change that?

Disable “Pass volume keys” under Menu → Settings → System → Audio/Video → HDMI-CEC; the keys revert to decoder volume [Elektroda, eprom1, post #17715528]

HDMI-CEC turns my Philips TV on only half the time—fix?

CEC reliability drops when cable length exceeds 5 m or devices sleep deeply. Use certified High-Speed HDMI under 3 m and set CEC to ‘Active Source’ on the VU+; success rates rise to 97 % [TechConnect, 2022; Elektroda, 19553880].

The remote became unpaired; the menu is unreachable—how to re-pair?

Access the box via OpenWebif, change Remote Control Code to 1, then press PVR + EXIT five seconds on the handset; pairing restores [Elektroda, ggeneja, post #20369577]

How many IR codes are stored, and what if none work?

The EPROM holds about 256 TV code sets; very new models may be absent. Use HDMI-CEC or buy a learning remote in that edge case [VU+, Manual v3.2; failure noted Elektrode, DarkElf, #20655915].

Channel +/− keys don’t zap channels—any workaround?

Install the free MultiQuickButton plugin, map Channel +/− to ‘Next/Prev Service,’ then reboot the GUI [Elektroda, Fotodetektor, post #16825879]

Why does the AV key not change sources on some TVs?

The key sends a single-function AV IR code. Many modern sets open a source menu that needs arrow navigation, so the remote can’t finish the task [Elektroda, raspi, post #20802755]

Could weak batteries cause programming failures?

Yes; IR output drops 40 % when AAA voltage falls below 1.2 V, leading to missed code entries [Energizer, Lab Data 2021].

What’s an easy 3-step summary for programming any VU+ remote?

  1. Enter programming mode (1 + 3 or TV Power + OK). 2. Input brand code or scan with CH+. 3. Save with OK; test power and volume.

Does remote latency increase after many CH+ presses?

No; the MCU cycles codes sequentially at a fixed 1 Hz, so response stays constant even after 150 presses [Elektroda, eprom1, post #17691990]
