Smart Home Gadgets That Are Actually Useful

No neutral wire required is the line that decides whether smart lighting is a weekend job or a rewire. It dims up to 150 W of dimmable LEDs or 600 W of incandescent and halogen bulbs. Clear Connect is Lutron's own patented radio and the Smart Hub is what gives you app control. It's the one proprietary stack I kept, because the paddle still works as a paddle when everything else falls over.

Under the dishwasher, under the water heater, behind the toilet: three of these cover the places a house actually floods. IP67 dustproof and waterproof means a real puddle does not kill the thing that detected it, and Aqara states one battery lasts over two years. Which radio it uses is not something the product page says, so treat the hub question as open before you buy.

Occupancy and proximity are both radar on this one, alongside temperature and humidity, which is why it heats the room you are in rather than the hallway the old thermostat lived in. A built-in air quality monitor nags you when the air goes bad. Alexa is built in; HomeKit, Google Assistant and SmartThings connect. Heating is where the money is, and this is the entry that pays for itself.

Zigbee is the reason lights on this system answer instantly instead of asking a server three states away for permission. The spec sheet claims 150+ lights and 50+ accessories, an Ethernet cable comes in the box because that is the connection Philips recommends, and the page says plainly that it works without Wi-Fi. Buy the hub before the bulbs; it is the part that makes the rest local.

Rated at 15 A and 1800 W for general resistive loads, it reports real-time and historical power consumption, which is how you find out what the dehumidifier really costs. Matter certification means it joins whichever ecosystem you already picked instead of adding one more app to the pile. The narrow body leaves the second socket usable, which sounds trivial until it isn't.

Floor cleaning is the only job here that hands back an hour a week, every week, forever. ClearView Pro LiDAR builds detailed 3D maps for room-by-room cleaning, and the dock's AllergenLock bags give up to 90 days of hands-free operation. Scheduling lives in the Roomba Home app rather than in any shared standard, which is the clearest place this list bends its own rule.

Each bulb is rated up to 810 lumen and speaks both Bluetooth and Zigbee, with Matter listed under third-party compatibility. Buy them for the two rooms where light genuinely changes your evening and leave the rest of the house alone, because color bulbs are what people purchase first and regret hardest. Run through a bridge on Zigbee rather than your Wi-Fi, they answer the moment you ask.

Keyless entry only earns its keep if it fails gracefully, and a mechanical key and NFC card sit alongside the fingerprint reader here. Ultra-Wideband unlocking as you walk up with an iPhone or Apple Watch is the party trick; Matter over Thread is the useful part, because Apple Home, Google Home, Alexa and SmartThings all see it. Aqara rates a charge at up to six months.

Matter controller and Matter bridge, both at once: supported Matter products connect straight to it, and the whole IKEA lighting range turns up inside whatever app you actually open. Cheap is the entire point. Nothing about the box is fast or clever, and after a year of running kitchen lights through one I have not needed it to be.

Up to 3 x 200A mains and up to 16 x 50A branch circuits, tracked every second: that is the whole pitch, and seeing your electricity broken out circuit by circuit changes behavior faster than any lecture. Control lives in Emporia's own app, which is where this one bends the standards rule. It mounts inside your breaker panel, so budget for an electrician.

Millimeter-wave radar is the difference between a light that stays on while you read and one that switches off mid-page. It detects up to five people at once and divides a room into as many as 30 zones, so the sofa and the desk can trigger different things. Integration needs no Aqara hub, which is rarer than it should be.

Retrofitting beats replacing whenever the window covering already exists and works. It clips onto horizontal blinds with a pole 6.2mm to 10.2mm across and runs off a built-in 2000mAh lithium battery that the bundled solar panel keeps topped up. Standards are conditional here: pair it with the Hub 2 and it speaks Matter, alone it is Bluetooth and a phone.

Two angled tweeters and one midwoofer give real stereo separation out of a single box, which is more than most one-piece speakers manage. Bluetooth 5.3 lets a guest play something without joining your network and AirPlay 2 covers the Apple half of the house, so it is not locked to one app. Line-in wants a separate adapter, an irritating way to sell a 3.5 mm socket.

Every house holds an appliance that will never be clever on its own: a window air conditioner, an old amplifier, a ceiling fan. Learning their infrared remotes into one app costs less than replacing any of them. The temperature and humidity sensor lives in the cable and is rated to plus or minus 1.8% RH, and Matter support extends to SwitchBot's own locks, curtains and blind tilts.

Press the button and the reading appears on the device itself, which is the part that makes it useful when your phone is in another room. It runs Matter over Thread, so you need a Thread border router. The DIRIGERA hub qualifies and so do plenty of others you may already own. Knowing the nursery sits colder than the hallway changes what you do next. Batteries sold separately, obviously.

CO2, PM2.5, temperature and humidity, all from one puck that takes USB-C power with the cable and adapter sold separately. Carbon dioxide is the number nobody measures and everybody feels, and it explains why a shut bedroom smells stale by morning. It wants a Thread border router such as the DIRIGERA hub. It cleans nothing; it tells you to open a window, which is usually the fix.
