    Netgear Orbi 770 and Aqara Camera Review
    This week we have a listener review of the NETGEAR Orbi 770 Series WiFi 7 Mesh System. These can be bought in One, two, and three packs costing $300, $550, and $700 respectively. Netgear's specs say that a single unit can cover up to $2750 square feet and a three pack can cover 8000 square feet combined. And just for good measure John talks about his experience with Aqara cameras.These are the same cameras Ara uses so let's see if John has similar results.
    Product Features:
    Tri-band hardware with a dedicated backhaul is meant to keep throughput more consistent when many devices are online at once.
    WiFi 7 peak rating is up to 11 Gbps and it also connects WiFi 6 and WiFi 5 devices; real speed depends on your plan and hardware.
    Devices can easily roam between the router and satellites.
    Setup, device management, and guest WiFi are handled in the Orbi app.
    Sold for use in the United States only.
    John Lyman's Review
    A few years ago, I replaced my old Netgear Orbi system with a TP-Link Deco XE75 mesh system. At the time, my older Orbi just wasn't able to handle all the devices we had in the house. After doing some research, the Deco XE75 and XE75 Pro had great reviews, so I decided to give Deco a try.
    The Deco worked, but as we added more devices—and because of the design of our house—I kept having to add more and more nodes to get good, consistent coverage. Even with gigabit fiber, I never really felt like I was getting the speeds I should have been getting throughout the house.
    When Amazon Prime Day came around in July, I decided it was time for an upgrade. At the same time, I decided this was going to be MY "year of home automation."
    Back to Orbi — This Time with Wi-Fi 7
    For the network, I went with the Netgear Orbi 770 Series Wi-Fi 7 mesh system.
    I considered going down the Ubiquiti route, but ultimately I wanted something easier to manage and more "set it and forget it." I spent enough time around networking years ago. These days, I'd rather leave my network-engineering hat in the past and have something that simply works.
    I've now been running the Orbi 770 for about four months, and—with one exception—it has been pretty much bulletproof.
    That exception was automatic firmware updates. I didn't realize they were enabled, and Orbi decided to install an update in the middle of the day. That's something I'd definitely check when setting up the system.
    Other than that, the performance has been excellent.
    I have AT&T Fiber with the AT&T gateway configured to pass the connection through to the Orbi. My office is upstairs and away from the main router, but I have my computer connected by Ethernet to an Orbi satellite. I'm consistently seeing speeds in the low 900 Mbps range both down and up.
    My media/home-theater room has historically been the hardest room in the house to reach with good Wi-Fi. With the Orbi, I'm seeing roughly 700–800 Mbps there over Wi-Fi, connecting on 5 GHz.
    More importantly, coverage throughout the house is now excellent and the system has been extremely stable.
    If you're considering a mesh system and aren't ready to go down the Ubiquiti route, I'd strongly suggest looking at the Orbi 770. Based on my experience with both systems, I'd skip the Deco, spend a little more and get the Orbi.
    The Orbi also gives you separate IoT and guest Wi-Fi networks. Devices connect quickly, stay connected and, in my experience, have worked considerably better than they did with my Deco system.
    Moving Away from Ring
    The next part of the project was home automation.
    Over the years, I had accumulated a hodgepodge of smart-home products: Ecobee thermostats, Ring doorbells, different cameras, Hue lights and other devices. Even the Ecobee that was supposed to work with Apple HomeKit would periodically disconnect.
    I wanted to simplify everything, and I particularly wanted to move away from Ring.
    While researching alternatives, I came across Aqara. They make doorbells, cameras, thermostats, switches, sensors and a number of other smart-home products, with particularly strong integration with Apple's Home ecosystem.
    So during Prime Day, I jumped in. I bought two thermostats, two cameras and two doorbells.
    There was definitely a settling-in period. Between changing the network and adding all the new smart-home equipment, it probably took about six weeks before everything really fell into place.
    Since then, however, it has been remarkably solid.
    The network can go down and come back up, and the Aqara devices reconnect on their own. About the only problems I've encountered have been when somebody physically unplugged one of the doorbell hubs. Since some of the other devices were relying on that hub, unplugging it naturally caused those devices to disappear as well.
    The $34 Camera That Surprised Me
    One of the biggest surprises has been the Aqara G100 indoor/outdoor cameras.
    I paid $33.99 each for them, and they've been excellent. For the price, I'm genuinely impressed with how well they've worked and how nicely they integrate into the Apple ecosystem.
    Security and privacy were also part of my decision to move away from Ring. I like having my cameras integrated with Apple Home and being able to use iCloud/HomeKit Secure Video rather than building my smart-home camera system around Amazon.
    The Doorbells — A Big Improvement Over Ring
    The Aqara doorbells have also worked really well.
    I have two of them. One is at our front door, and the other is on a door that we added to the house where I don't have wiring available. For that one, I use rechargeable batteries, and that setup has worked well.
    The front-door unit is very small and unobtrusive, which I like. More importantly, both doorbells have been rock solid.
    That's probably the biggest difference I've noticed compared with my old Ring setup. The Aqara doorbells are consistently connected and integrate directly into Apple HomeKit. I don't feel like I'm waiting for the doorbell to connect when I actually need to see who's at the door.
    They just work, which is becoming a recurring theme with most of the Aqara equipment I've installed.
    For me, replacing the Ring doorbells with Aqara has been one of the better parts of this whole home-automation upgrade.
    Aqara Thermostats — Simple, Which Is Exactly What I Want
    The Aqara thermostats were very simple to install. I was replacing my Ecobees, and the changeover was straightforward. They connected to Apple HomeKit easily and, since getting everything settled, they just run.
    Easy peasy. There's really not much more I want from a thermostat. I don't need it to be exciting—I need it to control the temperature, stay connected and work when I open the Home app. So far, that's exactly what they've done.
    One feature that really interested me is Apple Home's Adaptive Temperature. Instead of relying on a traditional fixed schedule, the temperature can automatically adjust based on whether people in your Apple Home are actually home or away.
    There are four modes you can configure: Home, Away, Night and Extended Away. Home and Away automatically adjust the temperature depending on whether anyone from the household is home. Night mode lets you set different temperatures for specific days and times, so the house can automatically adjust while everyone is sleeping.
    The one I'm particularly happy to have is Extended Away. When we're going to be gone for an extended period, the system can automatically adjust the temperature appropriately. That's one less thing I have to remember to change before we leave—and, more importantly, remember to change back when we get home.
    It's another example of what I'm looking for with this whole project: home automation that actually automates things instead of giving me another app and another device to manage.
    The One Finicky Aqara Device
    I also bought an Aqara Smart Climate Sensor with three programmable buttons. This has been the one finicky device in my Aqara setup.
    Getting it set up properly with HomeKit was a little tricky. Each of the three buttons is supposed to support three different actions—a single press, double press and long press—which theoretically gives you nine different programmable actions.
    In practice, I've only been able to get the single-press actions to work somewhat reliably. I currently use Button 1, the middle of the three buttons, and even that hasn't been as seamless as the rest of my Aqara equipment.
    That said, I like the concept enough that I'm planning to put a second one in my media room. The idea is to program the buttons for lighting and temperature control so the kids can simply push a button rather than flipping off the actual light switch—which, of course, defeats the whole purpose of having smart lights.
    So this one is still a work in progress. I really like what the device is supposed to do; I just wish the HomeKit button actions worked as reliably as the rest of my Aqara setup.
    Finally, One Home App
    That's probably the biggest improvement from this whole project.
    Instead of having different pieces scattered across different ecosystems, I can now open Apple's Home app and see essentially everything in one place.
    I've also settled on Nanoleaf as my primary smart-lighting platform. I still have some Philips Hue lights in the house, and I'm not ripping out perfectly good bulbs just for the sake of replacing them. As those eventually die, however, I'm replacing them with Nanoleaf.
    Four months into this project, I'm very happy with where I've ended up.
    For networking, the Orbi 770 has been fast, stable and about as close to "set it and forget it" as I could have hoped for. If you want a high-performance home network but don't want to make the jump into something like Ubiquiti, I think Orbi deserves a serious look.
    And if you're an Apple/HomeKit household and looking to build out a smart-home ecosystem, I'd also recommend taking a look at Aqara.
    The combination of Orbi, Aqara, Nanoleaf and Apple Home has finally given me what I was looking for:
    A smart home that doesn't require me to constantly mess with it.

    Podcast #1271: Consumer Reports HDTV Ratings

    25/09/2026 | 36 mins.
    On this week's show we take a look at the consumer reports ratings for 70 inch and larger TVs. We also read your email and take a look at the week's news.
    News:
    Your Google Home can now take orders from Claude and other AI agents
    Roku Adds 30 New Bundles To Premium Subscriptions
    Element Launches New TiVo-Powered Smart TVs in the U.S.
    Paramount Settles States' Antitrust Suit, Clearing Way for Warner Megadeal
    Consumer Reports Ratings for 70-inch and larger TVs:
    On this week's show we take a look at the consumer reports rating for 70 inch and larger TVs. This list was sent to us by Dermot who thought it may make a nice topic. We took the list and only updated pricing. So how does Consumer Reports determine a score for their TV ratings?
    Consumer Reports builds each TV's Overall Score from three buckets: lab performance, member surveys, and (for smart TVs) privacy/security. They do not accept manufacturer samples. Secret shoppers buy the sets at retail so they test the same units you would buy.
    They run 200+ TVs a year. Each set goes through 20+ tests and more than 500 data points in their Yonkers labs. Picture settings are optimized with the on-screen user controls only—not a full professional calibration. If a set needs a calibrator to look good, that hurts it.
    What the lab actually measures
    HD and UHD picture quality — test patterns plus real movie/TV clips for detail, black level, contrast, and color accuracy after the set is optimized.
    HDR — peak brightness (measured with a Photo Research PR-740 spectroradiometer), plus how well highlights and shadows hold up in dark and bright scenes.
    Viewing angle — color and contrast from both horizontal and vertical off-axis positions.
    Motion blur — how clean moving text and action stay.
    Sound quality — built-in speakers: clarity, bass, volume range, and distortion, compared against reference sets in the lab.
    Features / versatility — inputs, smart-TV functions, ease of use, etc.
    Data privacy and data security — whether the TV collects extra data, how easy it is to control that, encryption, known vulnerabilities, update practices. These scores are folded into the Overall Score.
    A viewing panel then watches real content side-by-side after the meter work is done.
    Survey piece 
    Predicted reliability and owner satisfaction come from CR member surveys, not from the lab unit they bought.
    Reliability is brand-level, not model-level. A statistical model estimates the chance a new set from that brand will have a problem in the first five years. They control for age, how often it's used, and whether it has an extended warranty.
    Owner satisfaction is how likely members are to recommend that brand. It is weighted at 5% of the Overall Score for every product category.
    Reliability's weight varies by category (typically 10–20%). For TVs it sits toward the lower end of that range because members rate reliability about even with picture performance.
    If a brand scores Poor or Fair on predicted reliability, that model cannot get a CR "Recommended" badge, no matter how well it tested.
    When they don't have enough survey data for a brand (like  on some Roku sets), they plug in category-average survey scores.
    How it becomes one number
    Overall Score is a weighted mix of the lab scores plus those two survey scores (and privacy/security). Models are then ranked against others in the same size group.
    That's why two 91-point sets can sit at very different prices: one won on lab performance plus surveys at a lower street price; the other is a more expensive flagship that still maxed the same scoring formula. 
    Brand            Model                  Overall     Score Price
    LG                  OLED77C5PUA   91              $1,800

    Samsung     QN77S90H           89              $2,600
    LG                OLED77G6WUA   89              $3,800
    LG                OLED77G5WUA   88              $3,150
    LG               OLED77C6HUP     88              $2,700
    LG               OLED77M5PUA     87              $3,870

    Samsung   QN75QN90F          82              $2,000
    Sony          K-77XR8B               78              $2,500
    Sony          K-75XR70                78             $1,500
    Hisense    75U8QG                   75             $1,700 (65")
    LG              75QNED92AUA      75             $1,680
    TCL           75QM8K                   74             Mostly Unavailable
    Sony          K-75XR50                73             $2,000
    Roku          75R8B5                    73            $1,250
    Roku          75R8C5                    72            $1,200
    Hisense     75U75QG                 72            $1,700 (65")
    TV COMPARISON SUMMARY
    TOP TIER (Score 88-91)
    LG       OLED77C5PUA     91    $1,800    Best score-to-price
    Samsung  QN77S95F        91    $3,000    Same score as C5, $1,200 more
    Samsung  QN77S90F        90    $2,500
    Samsung  QN77S90H        89    $2,600
    LG       OLED77G6WUA     89    $3,800    Highest-priced LG
    LG       OLED77G5WUA     88    $3,150
    LG       OLED77C6HUP     88    $2,700
    Our takeaway is that the only score that actually matters here is not "91 vs 89." It is that the LG C5 is tied with Samsung's flagship S95F at 91, and it is $1,200 cheaper. 
    If we were going to spend money for a 75–77" set, we would treat the list like this:
    Buy the C5 if the room is normal-to-dim and you want the best picture per dollar.
    Buy the S95F only if the room is bright, you want a matte screen, and you specifically want a bright picture. Do not buy it just because it is tied at 91.
    The Samsung S84F at $1,600 / 85 is the value model if you don't want to go OLED.
    Anything at 75 or below is fine for a secondary room. Especially when you consider models from Samsung and LG providing higher quality for barely more in cost. 
    Does Consumer Reports still matter? Yes, but not as the only vote, and not the way it did 15 years ago. There are other sources out there and each weighs aspects of TVs differently. With that said, they all agree that the LG C5 is a really nice TV.

    Podcast #1269: Is Your LG Smart TV Listening to You? and Dolby AC4

    11/09/2026 | 36 mins.
    On this week's show we look into an article that alleges LG's Smart TVs are listening in on your conversations even when the screen is off. We also do a quick rundown on what Dolby's AC4 is and where you can experience it. We also read your emails and look at the week's news.
    News:
    Streaming Is Raising Prices Faster Than Cable Ever Did
    More than half of consumers want live TV and streaming in one package 
    LG Smart TVs caught listening even with the screen off
    Stan from Pittsburg sent us a link to an article (LG Smart TVs caught listening even with the screen off) at FlatpanelsHD claiming LG smart TVs collect more data than many owners realize — including with the screen off.
    What the investigation found
    LG TVs use ACR (automatic content recognition): they snapshot what's on screen, including HDMI sources, for ad targeting. FlatpanelsHD notes this has been industry-wide for years, not unique to LG.
    The TVs scan the local Wi‑Fi network, identify other devices, and send back data such as IP address, location, and nearby network names.
    Voice features can transcribe speech after "Hi LG." The mic can stay active 10–15 seconds after silence. Researchers reported recording/transcription even with the display off, and that locally stored data can upload later when the set reconnects (including for a firmware update).
    That last point is presented as conflicting with LG's claim that its TVs "do not collect, record, or store ambient conversations." LG had not commented when the article ran.
    Flatpanel's Recommendation
    Turn ACR off if you can, or take the TV off the internet and use an external streamer (Apple TV, or Roku.). Firmware can be updated via USB instead of online.
    ACR is an old, industry-wide problem and it's unclear why the article focused only on LG. They still argue the mic/network findings are worth attention. They also link their earlier piece ranking Apple TV 4K as stronger on privacy because it doesn't do this kind of viewing tracking.
    Update - In a statement sent to Tom's Hardware, LG said "The claims made in the recently published video are not true. LG TVs process voice data only when the voice button on the remote control is pressed and held, or when a wake word such as 'Hi LG' is recognized after the user has activated the Far-Field voice recognition feature. Other than these instances, the TVs do not collect or record ambient conversations. (If the wake word is not recognized, no voice data is transmitted to the server; the audio processing for wake word detection is performed locally on the device and is immediately deleted.)"
    Dolby AC-4
    One of our listeners, Scott, sent an email asking us to discuss Dolby AC-4 so that is what we are going to do today! Dolby AC-4 is Dolby's next-generation audio codec for broadcast and streaming. It was designed as a clean-sheet replacement for the older Dolby Digital family, not as a tweak of it.
    Compared with Dolby Digital Plus, AC-4 aims for similar or better quality at roughly half the bitrate. It natively handles channel-based audio, object-based Dolby Atmos, dialogue enhancement, loudness control, multiple language tracks, and different renderings for speakers vs. headphones in one bitstream. There are several profiles/levels:
    Level 3 — the version widely built into TVs (broadcast/OTT Atmos-style delivery).
    Level 4 — fuller Atmos metadata, including headphone/head-tracking features.
    IMS (Immersive Stereo) — a stereo-plus-metadata flavor used for Atmos music on phones and headphones.
    Is it backwards compatible?
    No. An AC-4 bitstream cannot be decoded by a Dolby Digital (AC-3) or Dolby Digital Plus decoder. Old AVRs, soundbars, and TVs that only know DD+ (AC-3) will not play AC-4.
    What is compatible is the playback path in new TVs and set-top boxes. Those devices decode AC-4 internally, then output whatever the next box needs: PCM stereo, AC-3, DD+, or Atmos over HDMI. So the living-room chain can still work; the codec itself is not drop-in compatible with older Dolby formats. Services that must reach mixed old/new hardware still send DD+ or AAC as a fallback.
    Devices that support it
    AC-4 decoding is common in UHD TVs shipped since about 2017, especially models that already license Dolby Audio (Dolby has said it is in a large majority of new UHD TVs). Early public commitments came from Samsung, Sony, and Vizio; it is also in many Android TV / Google TV platforms and some Amazon Fire TV devices.
    It is not universal:
    Pre-~2017 TVs, most older soundbars/AVRs, and a lot of cheap streaming sticks do not decode it.
    ATSC 3.0 ("NextGen TV") tuners are the main over-the-air path in the U.S.; tuner support is still incomplete across brands and model lines.
    Most consumer AVRs still expect Atmos via DD+ JOC (Joint Object Coding) or TrueHD, not a raw AC-4 bitstream from the source.
    Note - JOC  allows an Atmos-capable TV, soundbar, or AVR to use the "JOC" metadata to build the immersive mix. An older DD+-only device ignores the extra data and just plays the core 5.1
    Studios and television
    Broadcast is the main home. AC-4 is an official audio system for ATSC 3.0 in the U.S. and is adopted by DVB in Europe. NextGen TV stations can (and some do) use it for Atmos, dialogue enhancement, and multiple presentations. Immersive AC-4 on U.S. OTA is still uneven; many 3.0 stations have not yet gone full Atmos.
    Streaming is later. Netflix, Disney+, Apple TV+, and most other major video services still deliver Atmos as Dolby Digital Plus + JOC. Peacock has publicly committed to AC-4 (alongside Dolby Vision 2), with rollout described as later in 2026. Atmos music already uses AC-4 IMS on several apps.
    Studios still master Atmos the same way. The delivery codec is chosen per platform: cinema TrueHD, most streaming DD+ JOC, NextGen TV and a few future streamers AC-4. AC-4 is in the pipeline; it is not yet the default living-room streaming format.

    Podcast #1268: Ara's New Setup First Impressions

    04/09/2026 | 54 mins.
    On this week's show Ara gives his impression of the new gear installed into his new home. We talk Internet, Home Networking, Automation, and Home Theater in an action packed show. We also read your emails and take a look at the week's news.
    News:
    Apple TV Hikes Prices
    SVS Releases SoundPath Multi-Band Wireless Audio Adapter
    Roku ups premium hardware with launch of its first OLED TVs
    Sonos Welcomes Beam Ultra and Sonos Ace Ultra to its System
    Ara's New Setup First Impressions
    Starlink Performance - We had no issues while we were in TN. The entire week no said anything about slow speeds and our streaming was no different than when we are in CA. I tested speeds from time to time and results varied but the slowest speed (22 Mbps) never impacted TV viewing. 
    Ubiquity Network Management - this is a different world! I am still exploring all the things you can do. But the system is setup like a business. You have a network and wireless access points. I have four. One on Channel 11, two on 6, and one on 1. It was setip so the channels are far apart and don't overlap. 
    MyQ & Honeywell (matter compatible) thermostats go offline from time to time. I restart the wifi access point and they come back. 
    Third Reality Garage Door Opener - 2.4 GHz, Scene Management
    Mantel Mount MM815 Motorized Drop Down & Swivel TV Mount - $700 The MM815 is a remote-controlled drop-and-swivel TV mount. Press one button to lower the TV to eye level and rotate it as needed. It comes with an RF remote, is silent, and has two memory presets.
    Sony BRAVIA 7 II PRO True RGB 4K HDR Google TV with Gemini (Model Number K75XR70PRO)-  $2300 The Sony BRAVIA 7 II PRO is Sony's 2026 mid-range True RGB Mini-LED TV (65 inches and up) with independently driven red, green, and blue backlight LEDs, XR processing, and about 2,000 nits of peak brightness for stronger color volume and contrast than a typical white Mini-LED. It is 4K at 120 Hz, supports Dolby Vision and Dolby Atmos, and has HDMI 2.1 gaming features (VRR, ALLM, 4K/120). Google TV includes Gemini for voice search and recommendations, plus AirPlay 2. The Pro bundle adds a three-year replacement warranty, a backlit rechargeable remote, extra Sony Pictures Core credits, and an enhanced Voice Zoom 3 dialogue mode; picture hardware is the same as the standard 7 II.
    Sonos Arc Ultra - $1099 The Sonos Arc Ultra supports Dolby Atmos that has a 9.1.4 driver layout and Sound Motion woofer to produce wide, height-enhanced surround and stronger bass from a single bar. It connects to a TV with one HDMI eARC cable, supports Wi-Fi, Bluetooth, AirPlay 2, and the rest of the Sonos ecosystem (including optional Sub and rear speakers), and can be controlled with the TV remote, Sonos app, touch controls, Sonos Voice Control, or Alexa. Trueplay tunes the sound to the room, and AI speech enhancement is meant to keep dialogue clear. It is a long, low-profile bar (about 46 inches wide) sold in black or white.
    Sonos Sub 4 - $899 The Sonos Sub 4 is a wireless subwoofer for Sonos S2 systems, pairing with current soundbars and speakers to add bass down to about 25 Hz. Two inward-facing 5-by-8-inch woofers and dual Class-D amps use a force-canceling layout so the cabinet stays relatively still and the bass stays clean. It has the same slot-style shape as earlier Subs, in black or white matte, and can stand upright or lie on its side. Updates over the Sub 3 include Wi-Fi 6, a faster processor, more memory, lower idle power, and a slightly lighter cabinet; setup is through the Sonos app, with optional Ethernet. Two Sub 4s can be used with the Arc Ultra.
    Audio Advice - I'll be in Franklin in October for a SVS/Audio Advice Event. Details to come
