Smart Home Gadgets Worth It: The Ones Their Own Makers Have Not Already Beaten

One test applied to eight products: is this still the best version of itself inside the manufacturer's own current range? Several popular recommendations fail it outright.

Worth it needs a definition or it means nothing. Here is the one used below, and it is deliberately narrow: is the product still the best version of itself inside its own manufacturer’s current catalogue? Not against rivals, not against last year, against the range the same company is selling today. It is a test a buyer can run in five minutes on a vendor’s own store page, and it disqualifies a surprising number of products that appear on best-of lists. Nothing here was tested in a lab. Everything below comes from manufacturers’ own listings and named reviews.

One question knocks out half of this category

The failure mode this test catches is specific. A product gets reviewed well, enters every recommendation list, and then the company that makes it quietly ships something cheaper, newer or better-connected in the same range. The old product stays on sale because it still sells, and the lists keep recommending it because nobody re-reads the store page.

So the question is simply whether the manufacturer’s own catalogue already contains a better answer to the same problem. Where it does, buying the older item means paying for the recommendation rather than the hardware.

It is also a test with an obvious blind spot, which is that manufacturers rarely announce a supersession. The old product is not marked down or labelled previous generation. It simply keeps its listing while the new one appears beside it, and the difference between them is a protocol or a price that only shows up if you read both pages.

Passes: the Caseta kit, with a ceiling worth knowing

Lutron’s Caseta starter kit passes cleanly. Lutron has not shipped a replacement above it, and the Diva dimmer and the original Caseta dimmer are both still listed as current parts of the same system rather than as an old model and its successor.

That does not make it cheap or perfect, and Consumer Reports is direct about both. Its review puts the starter kit at about 100 dollars and individual switches at 60 to 70 dollars, with low-voltage dimmers at 120, and identifies cost as the main drawback: Aqara switches run 36 to 46 dollars, Leviton 40 to 50, TP-Link 20 to 50. Consumer Reports also states that the hub caps at 75 controllable devices, which is a hard ceiling for anyone retrofitting a whole house rather than a few rooms.

The other thing to weigh is protocol. Consumer Reports says Caseta works with essentially everything except the emerging Matter standard. Buy it as a lighting system that speaks to your platform through Lutron’s hub, and it is excellent. Buy it expecting it to slot into a Matter house as a peer, and it will not.

Fails: the Kasa four-pack that is not the Matter one

This one fails on a technicality that costs real money. The commonly recommended Kasa plug is the EP25, sold in a four-pack as EP25P4, described by TP-Link as the Smart Wi-Fi Plug Slim with Energy Monitoring and listed as working with Alexa, Google Assistant or Samsung SmartThings devices. Matter is not claimed for it.

TP-Link’s own Kasa range contains a third, different model, the KP125M, which is Matter Certified and sold in two-packs and four-packs. It can be set up by scanning a code in the Alexa, Google Home or Apple Home app without installing the Kasa app at all. It is the same idea of a product from the same brand, with the protocol that determines whether the plug outlives the app it came with.

There is a second problem for anyone trying to compare them, which is that TP-Link publishes no price on its own product pages and sends buyers to Amazon instead. A manufacturer that will not state what its product costs makes value impossible to assess from the source. Do not buy the EP25 four-pack on a 2026 recommendation. If you want a Kasa plug, the model number to look for ends in M.

Nothing here says the EP25 stops working. It does what it did on the day it shipped, including the energy monitoring that is its main selling point, and TP-Link lists it with a two-year warranty. The point is narrower: two plugs from the same brand sit on the same store, and only one of them is built on a standard that outlives the app it shipped with.

Fails: the doorbell that vanished from its own maker’s store

The eufy doorbell most widely recommended is the battery-powered S330, also sold as the Video Doorbell Dual. It is not on eufy’s own doorbell collection page. The only S330 eufy itself lists is the wired one, at 109.99 dollars, marked 70 dollars off.

That collection page also shows what eufy would rather sell: a dual-camera E340 with a battery at 119.99 dollars, or 139.99 with a USB-C battery pack, plus a C31 at 84.99 dollars, a C31 with battery pack at 109.99, and a C30 at 59.99.

So the battery Dual is a product still findable at third-party retailers but no longer stocked by the company that has to support it. eufy has published no formal discontinuation notice, which is exactly why the store page is the more reliable signal. Buying one now means buying hardware its manufacturer has stopped selling, from a seller with no obligation to tell you that.

Fails hardest: the vacuum its maker now takes only as a trade-in

The Roomba j7+ appears nowhere in iRobot’s own Roomba store as a purchasable product. The j7 shows up only in the list of models iRobot accepts for trade-in. There is no clearer statement a manufacturer can make about a product’s status short of a press release.

The current lineup on that page starts at 249.99 dollars for a Roomba 105 Vac with an AutoEmpty Dock and 269.99 for the 105 Combo with the same dock, then runs through 469.99, 799.99, 1,299.99 and 1,399.99 dollars. Self-emptying is no longer a premium feature at this company; it is the entry model.

Anyone still weighing a j7+ against a current model is not comparing two products in a range. They are comparing a discontinued item against the range that replaced it, at prices that have moved substantially in the buyer’s favour.

Passes narrowly: Wyze Cam v4, current only because nothing followed it

The Wyze Cam v4 passes the test, and it is worth being precise about why. Wyze’s full camera catalogue contains no v5 and no newer standard indoor or outdoor camera, so the v4 is genuinely the current generation rather than a survivor.

That catalogue lists the v4 at 37.98 dollars, alongside a Cam Pan v4 at 49.98, a Cam OG at 29.98, a Battery Cam Pro at 59.98, a Video Doorbell v2 at 59.98 and floodlight cameras at 74.98 and 119.98. It is a coherent range with the v4 at the sensible middle of it.

Passing this particular test, though, says nothing about whether the company is a good custodian, and that is the limit of the method. The v4 is the current model at a price nothing else matches. Whether that is worth it depends on questions this filter does not ask.

A related caution about reading store pages, since this whole method depends on them: Wyze’s own site is not internally consistent. On the same day, the v4 product page rendered all three colours as sold out or unavailable while the camera collection page listed it in stock at the same price. Where a manufacturer contradicts itself, take the more cautious reading and check availability before ordering.

What this filter cannot tell you

Catalogue position is a fast, checkable proxy, and it catches the most common way a recommendation goes stale. It is not a complete answer, and it is worth naming what it misses.

• It says nothing about the manufacturer’s finances, its ownership, or whether it will exist in five years.
• It says nothing about security or privacy history, which for cameras and doorbells is often the deciding factor.
• It says nothing about subscriptions, since a plan is priced separately from the hardware it unlocks.
• It cannot see products a company is about to launch, only what is on the store today.
