  1. Just in case anyone runs into this, you do have to remove the 3 screws on each side in order to slide the top/sides of the case backwards to get access to the drives and electronics. They really should update the PDF, or at least indicate you might have one case or the other, and show both. I don't know which is the 'newer' case design, or if both are used.
  2. I have had increasing episodes of hearing a 'chirp' from this NVR, followed by a reboot of the NVR about 60 seconds later. Talking with Luma support indicates a failing HD is the most likely cause, and they have sent me a new HD to replace the old one. The problem is the case on my unit is different from the case shown in their Manual PDF. Their instructions show removal of 2 screws on the back, and then sliding the top forward. On mine, the top doesn't have the 'indent' shown in their pictures, and the top and sides are one integrated piece of metal. It seems that I would have to remove some, if not all, of the screws on the sides (one toward the front, and a pair toward the rear, on each side) to be able to then slide the top/side cover back and be able to get to the drives. I don't want to create problems by removing screws that should be left in place. These are the relevant photos from the Manual, with a pair showing my Actual case. The label on my case is "LUM-510-NVR-4CH-1T" so it is the same as the manual indicates, but the case is definitely different. It's a Sunday, so thought I'd see if anybody here was familiar with this, and could advise on which screws I should or shouldn't remove.
  3. For what it's worth, that had been my approach as far as High Lamp only for HDR (and 3D) for the past several years, for exactly this reason. But edit: *not* long after getting the NX7, I've changed it. I have a large screen (160" diagonal 2.35:1), and so generally have the iris wide open, for both Low and High Lamp. What I decided is to keep it in High Lamp, even for non-HDR content, and then close down the Iris to the same light output as I was getting in Low Lamp. This increases the contrast significantly, for a better picture overall. And if I then need to replace the bulb sooner than otherwise, I'm okay with that. I've spent so much on this stuff that what's an extra bulb going to mean?? 😁
  4. I can't speak to the Apple TV, but in general for Netflix and Amazon, there is a lot of 4k content that is *not* HDR. In those cases, Rec-709 would be the appropriate choice. But if it is streaming HDR, then BT.2020 should match, and look best.
  5. I set up my Theater a couple of years before I got involved with Control4. In order to run an ethernet cable to the Projector, I would have to get a wider raceway, as the current one is completely full (I run speaker wire for my rear Atmos speakers through there as well). Basically it would be possible, but a significant hassle. If I were starting from scratch, then I'd probably go the IP route. But in terms of day to day operation, the IR I have has been completely reliable, and hasn't prevented me from doing anything I have needed it to do.
  6. I find IR control on my JVC NX7 very helpful and important - switching Anamorphic Mode, Installation Mode, etc., according to the Aspect Ratio of what I'm watching. IR has been completely reliable.
  7. Did you ever resolve this? I have a Luma NVR and hear a beep on occasion from that general location. I thought initially it was coming from a nearby Kwik-set Doorlock, but now I'm wondering about it. I usually have Internet Explorer open on a 2nd monitor on my desktop, signed into the Luma interface, so I can see the camera feeds live. Every so often, it spontaneously logs out, and I have to wait a few minutes to to get the feed back when I log in. The last time I heard the beep, within 30 seconds or so, the NVR got logged out from Internet Explorer, so this is pretty suggestive of what Cyknight indicated above. Is there any way to troubleshoot this further to pinpoint the problem, and therefore the solution?

    A couple of questions on the C4 Roon Interface (this is mostly with reference to playing Podcasts, but would also apply to music): Can you fast forward or reverse within anything that you're listening? I don't see button controls, just the ones to skip to the next song. But it looks like there's a progress bar that might hopefully enable you to move forward or backward within what is being played? Does it "remember" the point at which you were listening when you then stopped? I'll often listen to long podcasts, and when using Roon (non-Nucleus, so the Roon interface), if I pause, it will let me go directly back to where I left off. If I listen to my own downloaded media with the C4 digital media interface, it doesn't seem to be possible to either fast forward/reverse, or remember position, and no progress bar either. Thanks.
  9. I went ahead and created a Variable, setting it to True or False at the appropriate times, then programmed in the Conditional, and it seems to be working correctly. I added an AND to the Conditional (If Fan Speed doesn't equal 4) which should prevent it from slowing down or turning off when I have Exercise mode turned on (both fans at 4). But I would still be interested in what you find, since the logic seems straight-forward. Thanks for your help.
  10. Thanks for the reply. 1. Interesting point that I hadn't considered. But I do have a Scheduled Event at 11:30 every night where I included turning off both fans, along with lights, garage doors, locks, etc. So that should take care of that potential problem. 2. I'm on 3.1.3. 3. I thought about this as well, and may do that if the "time between" conditional won't work for whatever reason.
  11. I have a Z2IO near where my Projector is mounted about 9 feet up, in a room with a 13' vaulted ceiling. I also have 2 ceiling fans. During hot days, the space in the vault holds a lot of hot air. I want to program such that when the Z2IO temperature is above 78 degrees, the fans will turn on, and when the temperature is 78 or below, it will turn them off. I programmed off the Z2IO Local_Temperature Variable as follows: When Z2IO Local_Temperature Changes: If Z2IO Local_Temperature > 78 Turn Fan on Medium-High If Z2IO Local_Temperature </= 78 Turn Fan off Programmed like this, it works perfectly. But I would like this to function only between 7:00 AM and 10:00 PM, so using the Scheduler from the 'Device Actions' Panel on the right, using its Conditional Tab, dragged "If time is between 7:00 AM and 10:00 PM" to the Script Window, and then Nested the 2 Conditionals under it: When Z2IO Local_Temperature Changes: If time is between 7:00 AM and 10:00 PM If Z2IO Local_Temperature > 78 Turn Fan on Medium-High If Z2IO Local_Temperature </= 78 Turn Fan off But when I do this, the Temperature Change event no longer triggers any actions, and I don't see why. When "If time is between 7:00 AM and 10:00 PM" is True, then I would have thought that the same code underneath it should execute, just as it did when that conditional wasn't there. But that doesn't seem to be the case. I thought about using "While" rather than "If" but wanted to understand what I'm missing to begin with. I also want to add a Conditional so that when I have the Fans on High for when I exercise in there, the code won't execute, but wanted to get this straightened out first. Thanks.
  12. This can be done readily, but the problem is the DS2's Motion Sensor is not IR based, it is optically based. So on a partly sunny/cloudy day, for example, there would be very frequent false positives. I was doing this a while back, and eventually stopped because it was too intrusive. I ended up installing an Axxess Industries Motion Sensor above the door. This is much more useful, with very rare false positives (a neighborhood dog most of the time!). I use this all the time, using its motion detection to display the video from my DS2 on a T3 in our Family Room, which is where we most usually hang out. I also have it set to trigger an email, with a photo from the DS2, so if we're away from home, we'll still know a package was dropped off, or somebody was at the front door.
  13. I haven't found a way to have Pause/Play, Forward/Reverse, Volume Control, Room On/Off all in one interface, so came up with a workable compromise: I have an older Microsoft Surface 3, about the same size as the T3, and have Roon running on it. This gives me access to and control of downloaded Podcasts. I have Bluestacks running on it as well, so have the Control4 Android App available as well. By appropriately sizing and placing both of these apps, I have quick touchscreen access to all of these functions. The attached screen capture shows this. Not as 'clean' as a single interface with all of this functionality, but should readily serve the same function.
  14. Thanks for the reply - you could be right. I'll keep searching see what I can find.
  15. Ok, I added ShairBridge, selected my Theater as the default Room, and it connects fine. As you said, it needs to be initiated on my Phone, but that's not a big deal. It does give me volume control and Room Off, which is nice. But is there some way to have Pause and Play via Control4? I realize I can't forward/reverse, and Roon will remember my 'place' in the Podcast, but being able to Pause/Play would be nice.
