    More ambivision cons


    Since it depends on a camera and automatically adjusts the gain according to the screen brightness, when moving from a dark scene to a bright one it takes 1 second to adjust. It doesn't cripple the experience, it's not even noticeable when watching the sceen, but if you seek it you find it. It can avoided by disabling the auto camera gain but then dark scenes always leave the strip off.


    in the end I don't love any system (govee, philips, hyperion, ambivision).. this one is the least worst for my needs. With hyperion I believe I'd love the way it breaks the colors and matches the screen, but I'd hate to give up on my TV apps and be HDMI dependant.. I really can't tell which one is better tbh.


    Is there any hope that Hyperion will ever be compatible with the built in TV apps? that would be the perfect ambilight

    I wish you much happiness with your setup, but be honest and let us know how happy you are with that system in the long run 》 ofcourse we want an update !


    I'm back. Ambivision arrived a week ago and I can finally make an update now that it is 90% calibrated. Long story short, it's just outstanding although it has its flaws.


    It's been a nightmare to calibrate. It has values that need to be calibrated both on how the camera sees the screen, and after that, how the colors are reproduced in the led strip.


    There's R G and B gain values for the camera as well as an auto camera gain range which adjusts how the camera captures the screen depending on how bright the content is.


    On the led strip side, there's gamma correction, saturation correction and color curves for every channel. Leds are addressed individually much like hyperion and unlike Philips, whose gradient led strip has several sections of 10 leds each, which look ugly to me. In the app it's mandatory to set how many leds are laying in every side of the TV, like hyperion I believe? it doesn't get any more precise than this.


    One of my major concers, which was latency, vanished the first day. There's no latency, not even with at 30% smoothing effect, which is more than needed for a fluid performance. Even at 100% there's not much latency and at 0% there's no flickering, so all in all, zero problems with that.


    On top of that, it has an API with which I can easily control the led strip through Node Red. It has been integrated in my smart home seamlessly.


    It has a beautiful effect perhaps due to the camera setup? Playing Death Strading for example, when an image with a very bright sky on the top half is displayed and dim grass in the top bottom, the led strip only represents the top half with a beautiful pure white. Hoever if you turn down the camera so you don't see the sky and see only grass, suddenly it represents the grass with a beatiful dim yellowish green. You go back up, and the dim green dissapears. It's beatiful because it behaves just like the human eye.


    Now the cons. The app crashes a lot, there's a lot to improve in the whole system since every now and then certain settings go back to default and I need to open to app to readjust them (thankfully color calibration stays intact. Only smoothing and some other minor things). Support sucks, you have to figure out yourself almost everything. I hope it keeps up in the long run?


    So, concluding, and I hope I don't get much hate, I can only thing of one reason I would go the hyperion route and that is color accuracy. I believe with Ambivision it's just not possible to get a 100% absolute perfect color accuracy given how the system works. I do believe that's feasible with hyperion although I have found just one guy in this forum who has been able to achieve that with hyperion. However, when looking at the screen, 90% color accuracy feels like a 100%. For the rest, IMHO Ambivision just outweights Hyperion by far. (CEC,HDR,4K,FHD,HDR10,TV shows, TV sports, infinite inputs, built in TV apps, etc...)


    However, I understand you guys going this route instead of Philips, I definetely share that.


    Porbably in the future I'll give hyperion a go in smaller project. Maybe for the kids console or something of the like, because I'd really really love to delve into it and get 100% perfect color accuracy.


    Thanks for your input. It's not the difficulty of building it what's holding me back, it mainly is the amount of money.


    Can you guys think of an hyperion setup that matches my needs (CEC, 4K, HDR, Prime Video and Netflix compatible) and doesn't cost more than 200€? If there is, I would really re consider. I would love to use the built in apps from my smart TV, but I could give up on that.


    Been looking in the forums to make an Ambivision like build with Hyperion, but a fellow here put it clear that it's not feasible for various reasons. You know, the camera setup saves a lot of money


    However, if there's a setup that fits my needs and doesn't go any higher than 200-250€ at the very most, I would really reconsider.


    thanks again for your help, I'll check out the forums. For the moment I believe I'm gonna order the ambivision pro and test it out for 14 days.. if it doesn't please me I'll return it and dive deep into this forum


    btw, i like the camera setup in Ambivision because they will avoid going down the route with CEC/HDCP/HDR and Dolby Vision and what else for problems you can have to transmit data over HDMI. That's something you have to deal with when running Hyperion setup.


    that's the main reason I'm leaning towards Ambivision. Worse color accuracy, some lag but in that regard fewer headaches and, if it lasts a long time, much less money. I would hate to replace my led strip parts or whole setup with every new incoming device (PS5, TV, etc)

    so, with all respect and in few words, one can find hyperion worthwhile if one is a geek :)


    I mean, I'm up to it if it's worthwhile. I built my smarthome with HA starting with zero programming knowledge and I loved it.. the end results with HA are way better than with any other system, that's why I dived in programming despite the difficulty.


    I'm not sure that's happening with hyperion, not sure it's worthwhile.. and I wouldn't do it just for the sake of doing it myself.. specially considering that one might end up spending even more money that with a high quality end device.


    It's like building DIY door sensors for HA that cost you more money that the greatly working Xiaomi sensors.. why would I do that? only if I'm a geek I guess :S..

    mate, this is what you are buying >>

    so how i see it, Hyperion wins big in my book if i compare to this video, the lag is not worth the price reduction that you have with this system.
    i see it now and already bothers the hell out of me >>> leds are not following the image fluently. . :LOL::brb:


    Yeah, you're right with that. I'm giving up on lag and color accuracy vs other things. I'm not ok spending too much money into an ambilight system and this one seems good enough for me. As you said, with certain settings (no smoothing, no effects), ambivision can achieve a nearly zero lag experience, you can check it out in the video below. But yeah, I'm with you, ambivision doesn't match Hyperion's results, I don't even expect it.


    Still, same question remains, seeing what you have spent to make your built, why didn't you just buy the philips sync box?


    It's just DIY generally implies saving money and that is not happening here.


    Don't take it personally, I'm just informing myself and maybe, depending on what I get here, I'll put back my order.


    Video with nearly zero lag, I don't believe you can notice it.. specially if you watch the screen:

    Hahaha what do you want with this topic, for every build there are customization options.. depends on the wallet, time, craft, quality and what not.


    Indeed Hyperion.ng is not out of the box as Ambivision.


    I wish you much happiness with your setup, but be honest and let us know how happy you are with that system in the long run 》 ofcourse we want an update !


    So I'm not missing anything you mean? why not just get the Philips Hue system in your case for example? or the lightpack?

    Hi guys,


    I've been reading just a little bit here and there in this forum. I documented myself to some extend and I can't understand the point of hyperion, I assume I'm missing something. I hope more documented people will be able to answer.


    In my particular situation I wanted to build a system that allowed all my external HDMI devices to be connected to the light strip. I needed it to be HDR, 4K, CEC, Prime Video and Netflix compatible. After making some research I realized it was not viable since all required components (HDFury among them) were more expensive than, for example, the Lightpack UHD, so why should I bother? Even nearly as expensive as the Philips Hue system.


    So I narrowed down my requirements to just PS4 games. Again did some research and in the best case scenario, purchasing from Ali that is, the equipment's cost raised to 100€. A hundred euros for equipment without warranty, which I don't love. I'd rather pay more and purchase it from Amazon but then the bill increased to 150€. Again, what's the point of Hyperion?


    It's 150€, or 100€ if you preffer buying from Ali, that only works for one device (PS4 games in my case), no HDR, no CEC, no Prime video nor Netflix. If you go really cheap and buy a video grabber of questionable quality you might cut down the costs by 30€ but I'm not sure that's something I'd like to do.


    I am ordering the AmbiVision PRO for 235€, 100% compatible with all current and any upcoming video/audio features from the unforeseeable future. Smart features wise, it has an API to build a component or, if you're not into it, it can learn up to 3 IR commands to move between modes and turn on/off, so a broadling turns this device into a smart light strip. The app goes pretty deep into color customization, it looks very similar to hyperion to be honest. And of course it works with anything that is displayed so, regular TV channels and any other source will work as well.


    It feels like it's just the challenge of putting it together by oneself, not much more.


    Why are you going the Hyperion route?


    Thanks in advanced

    That's really helpful, I'm definetely gonna check that out. But before that, my Pi is far away from my tv. As far as I read, I can use WLED to send color information to the leds wirelessly, but the video capture still needs to be plugged, right? is there a workaround? I can't move my PI near the TV.


    Thanks again!

    It's a pi 4 and yeah I'm using the HA operating system which I'm afraid won't allow me to do that setup?


    tbh I decided to try DIY since I was expecting to get a cheap ambilight but so far I don't see that. Buying the components in Amazon goes up to 180€ already.


    thanks for your help

    Hi guys,


    As the title says I'm a newbie yet I'd love to build my own ambilight. I have very little knowledge of electronics, I just have a pi running my smarthome using HA, nothing else.


    I have a Playstation 4 working at 1080. Is there any tutorial for complete noobs?


    Can I use a raspberry pi zero w? I don't find many guys using it


    Which is the best/easiest way to build an ambilight for my PS4? In the coming 2 years I'll be buying a PS5 so I'd like to build a system that doesn't go obsolete by then.


    It doesn't need to be the cheapest, led colors are the most important. I need it to be CEC compatible.


    Well thanks in advanced for any help

    I believe this video shows it can be done with a camera and, as far as I can see, with great results. It's the Ambivision PRO. There's no lag there.

    Do you believe something like this could be achieved with hyperion?
