TV manufacturers have rushed to improve their latest models with fast HDMI 2.1 ports capable of supporting 4K gaming at 120Hz in glorious HDR. Unfortunately, most of the same models still use outdated 100Mb Ethernet ports.
Most new TVs support 5GHz and 2.4GHz wireless networking, but Wi-Fi is notoriously temperamental. Even though 5GHz networks have a theoretical maximum speed of 1300Mb/sec, many confounding variables can affect real-world performance. Ethernet is far more reliable in this regard.
To which I’d like to add a Hell, yeah! At least in so far as avoiding Wi-Fi is concerned.
As a household that has several Amazon Echo devices, I feel obligated to share the news about Amazon Sidewalk, including how to disable it.
What is Sidewalk?
Sidewalk is a “feature” in the latest firmware for the current generation of Amazon smart home products, including; Echo smart speakers, Ring doorbells & security cameras, and Tile trackers. When enabled, Sidewalk capable devices used by neighbors, visitors or passers-by are able to leverage your local internet connectivity.
Amazon says that these Sidewalk interlopers are allowed a limited amount of bandwidth, just 80 kbps, which is about the same as a tradition VoIP phone call.
That’s simple – ubiquitous connectivity is very convenient. Amazon knows this from years of experience. For example, their WhisperNet was a mechanism leveraging AT&T’s 3G mobile network to provide ubiquitous connectivity to early Kindle e-book readers.
Imagine someone who uses Tile Pro to track their car keys. They are, as so many do each day, dropping their child off at Travis Elementary School, which is across the street.
It could be very handy if their Tile Pro found our front room Echo Dot, allowed it to ping Amazon servers. If they later lost their car keys, Amazon would know they had been near our home. Presumably, Amazon would have a more detailed record of their location that might otherwise be possible.
We have quite a lot of IoT stuff hereabouts. One device that’s hardly had any mention is the Netatmo Weather Station. I honestly can’t recall how long we’ve had it. Perhaps as much as five years? I think it was a Christmas gift, since it does not appear in my Amazon order history. I’ve been pretty happy with it. It pretty much just works.
The basic kit includes on outdoor module (House) and the main indoor unit. I really like being able to know the precise local conditions, not the exaggerated conditions local broadcasters report from northern counties or down in Galveston near the gulf. They always go for the more dramatic presentation.
Some years ago I installed a MaxSeal pet door into one of the French doors that leads into my home office. This lets Shadow & Gwen wander in and out over the course of the work day. I opted for their dual-flap model, which aims to be more weather-tight. We get heavy rain, and there’s no point in attempting to air condition the back yard.
In general, we’re very happy with the pet door. Where “we” are the two quadrupeds, who like their independence, and the bipeds who don’t want to be pestered about every possible coming or going.
If there’s one complaint I have about the dog door it’s the clatter it makes when it closes. Each flap has six metal clips that swing past magnets embedded in the aluminum frame. This acts as a brake for the flapping action, and holds it closed between ingress/egress events.
