USB - HDMI-CEC Adapter

Works perfectly! Moved from Raspberry Pi LibreElec to Intel and lost the native CEC functionality provided by the Raspberry Pi. Plugged this in, and remote functioned exactly like before (with Raspberry Pi). Highly recommend this solution for anyone else in a similar situation!

First, Pulse Eight is refusing to refund my money. Second, you have to run buggy software in the background with this product and apparently that software doesn't work with Windows 8. Third, when the product doesn't work (which is for probably 80% of TVs), it's hard to figure out if it is the device, the software, the TV or the OS that you're running. I have a nice, new LG LED TV that supports CEC, and I'm running Windows 8 on an i3 box with 8 GB RAM attached to the TV.Support takes on average three days to respond to each inquiry by e-mail and they don't take calls, so you are stuck taking at least two to three weeks to troubleshoot the device because each time you try a fix they suggest and it doesn't work, you have to wait another two to three days for them to respond.I spent ten hours troubleshooting this device, which is roughly how long a person would spend pressing the on and off button on the TV remote over a period of 150 years. Do yourself a favor and just use the extra remote and press "on" instead of doing this. It's not a problem worth solving. Eventually TV manufacturers will fix this and that's when it will be worth it because it won't be a huge waste of time. The product is only useful for people with a compulsive disorder who are permanently unemployed and friendless.Also, shipping to and from the UK is about $30, so unless you are confident at they will actually refund your money, don't bother sending it back. I spent an extra $16 sending it back to the UK certified mail and they won't refund my money. Now they have the product and my money. Avoid this product like the plague.

I put off buying one of these for years but after looking for a way to eliminate extra keyboards/mice on my desktop it became the ideal solution.I have been using it with Kodi on Windows so that I can use my Samsung The Frame remote to control the interface for the past few months without a single issue. My favorite function though isn’t control at all but the fact that my TV will now power on or power off without me picking up the remote at all. Like a typical monitor that goes into standby the TV will turn off in accordance with windows power settings, and will turn back on as soon as the PC detects activity (like wiggling my mouse).It’s great. If you have a use for it, there is no substitute.

For CEC this works great no issues. There is an open source library that you can use to created your own CEC control apps. There are also 3rd party apps that allow you sleep and wake your TV like a monitor or switch off your AV receiver; which is probably why you’re looking for this product anyway. If you have problems sleeping your PC its probably a software issue. Look for another 3rd party app or change your USB sleep settings.As noted by the manufacturer this product will not work at 18Gbps. This means high bandwidth modes such as 4K 4:4:4 @ 60Hz does not work. Since it is a passive coupler it will pass the signal but it degrades the signal too much to work reliably. It really should be updated to work with current HDMI standards since $5 couplers work without issue.If you need full HDMI 2.0b functionality you’ll need to buy a splitter to split your video card output between the TV or other AV equipment and this adapter. Make sure the TV side of this adapter is plugged into the one of the splitter outputs. Some splitters will not split the signal if it does not detect a valid HDMI device. In that case you’ll need an additional cable to run to your TV or better yet use a HDMI dummy plug to spoof EDID. If you want the technical details: CEC works over a shared 1-wire bus. That means as long as your splitter supports CEC passthrough it will work. The same signal travels bidrectionally between all connected devices; when you issue a command every device receives it and then determines if it was intended to it.You can also use a custom cable with the CEC pins (13 & 17) split out but this is a far less practical solution for most people since an improperly shielded cable will likely degrade the signal anyway.

There was once another similar "Rainshadow" device but alas, that one is no longer on the market. The Pulse Eight device is still available and supported with good Open Source drivers. On its own, the device makes its presence known on the CEC bus, registering its own Logical Address and answering basic CEC queries, or you can put it in monitor mode and it just listens in on the CEC bus without allocating a Logical Address or automatically acknowledging any other CEC packets. You can then send arbitrary CEC messages under PC control. It also has a CEC input port which you can connect a different device to, so it does not waste a HDMI port on your TV.
