    Extend Light strip cables (Neo 2.0)

    in General Discussion

    They are just too short for my 77", I can't even reach like 5cm below the TV when going through the middle. Since I don't want the Neo box AND HDMI splitter behind the TV (its really closely mounted to the wall), I need to extend it the two light strip cables.


    I emailed support if I could use a USB extension cord, I got the reply "I believe it can be used in the USB extender to lengthen it". Cool, so I tried.


    Well that idea went up in smoke (literally). Luckely only the extension cord is fried. Are there any USB extension cords that can handle the power? Or any other way around my problem?

    Dear all users,


    For the USB extension cables, our team has working hard on the official type which can support Lytmi LED Strips. It will be released in the future on our website.


    Due to the various specifications and lengths on the market now, it might cannot be compatible with the light strips transfer.


    We appreciate all your valuable suggestions and honest feedback, which is greatly helpful for us to further improve our products. Our developing team is working hard on the extension cables.

    I have contacted support a couple of times asking for what USB extension cable they recommend. The answer is always the same: "Please try with 2.0 USB cables. Due to various specifications of the USB extension cable, we cannot guarantee that it will work. Our light strip does not support USB data transfer."


    To be able to light different colors an addressable LED strip must be used. Addressable LED strips work using 3 lines: power, ground and data.

    A close inspection to Neo's LED strips reveals three contacts. It also reveals one WS2811 controller per segment (http://www.world-semi.com/technology/details-129-3.html) so, it's a regular addressable LED strip.


    Since USB 2.0 Cables have four contacts (plus shield) my guess is LightMi is using three of these contacts in a particular way. Hence, the remark "Our light strip does not support USB data transfer."


    The USB standard calls for contact 1 and 4 for power while 2 and 3 are for data transfer. It would be much easier if LightMi would disclose the way they are using the USB A connector, but it seems we will have to find it by our own.


    A simple explanation on how addressable LED strips work can be found here https://electronics.stackexchange.com/questions/249162/how-does-an-addressable-led-in-a-strip-work.

    Hi sorry to hear that, but this is kind of high demanding and the lights' synchronization functions is kind of delicate, so it's not recommended extending the light strips.

    Im glad I came to the community 1st before purchasing. I want this product so bad, but want to make sure it can accommodate my setup 1st to avoid a return. I currently use a LG 77" GX OLED. So because my unit is flush mounted to my wall, I too intended to run usb extension cables since the sync box would not fit behind the tv. Sad to hear there is no remedy for this. I will not be able to buy this product for this reason. In the future if there is a update to this solution please let me know. I'd love to purchase this product.

    I was using usb extenders and the device didn’t work. I found away to tuck the lytmi behind the tv without extenders and now it works

    Hi Chris, maybe your can share how you manage to do it, it seems so many people have this kind of issue, as for the time being, it takes time for us to just extend the cables.

    Keen on hearing solutions on how to extend the usb reach. Tried USB extension cables and it didnt work. Has anyone tried 3.0 extension cables?

    @Tom Arran I did and the lights were all flashing randomly wouldnt change color and the neo 2.0 wouldn’t connect to the app had to remove them and wire everything up behind the projector screen. they just need to add in that extra length for these larger sized kits.

    @Jason Thompson oh :(. Not really an option in my setup. perhaps they are non standard USB cables. I would buy a 2m extension kit for sure!

    Hi @Jack - can you share how the cables are internally? ideally I would like to make my own to extend the functionality

    I seem to have the same issue. I am using USB extenders too but the box is not detecting the light strips… I will have to mount it behind my tv and try again.
