Purpose-built for the multi-cat problem. Each cat wears an RFID collar tag, and the feeder's lid and bowl shields only open for the right cat — so the food thief stays out and a pet on a special diet, weight plan, or medication schedule gets its own portion. The app tracks who ate what, when, and how much — useful for spotting appetite changes early. A 3L hopper holds roughly two weeks for one cat, dual-band Wi-Fi keeps the connection and low-food alerts reliable, and a backup battery keeps meals on schedule through outages. One constraint: it only recognizes the provided collar tags, so factor in tags for each cat.

In an iPhone household, this is simply the default tracker for keys, a bag, or checked luggage. The second-gen AirTag taps the Find My network to locate what you've misplaced, and upgraded Ultra Wideband and Bluetooth chips push both ping range and Precision Finding farther — now with step-by-step directions on Apple Watch as well as iPhone. A 50% louder speaker makes the last few feet easier, and you can temporarily share an item's location with trusted contacts or over 50 airline partners. Battery lasts more than a year and swaps easily. The catch is obvious: it's built for Apple, so Android users should look elsewhere.

Made for the fixtures where the bulb is the decor: pendants, exposed sockets, and Edison-style lamps. The tubular filament shape looks the part, but inside it's a full LIFX color bulb, with SuperColor delivering far richer saturation than typical RGB and white tuning from a warm 1500K to a crisp 9000K. The trick most filament bulbs can't match is 52 independently controlled zones in one E26, giving you real gradients, fire and aurora effects, and per-zone music sync. Setup is painless: screw in, scan the QR for HomeKit, no hub needed. It works natively with HomeKit, Alexa, and Google over Matter, and answers to all three by voice.

When you want the smart outlet to disappear into the wall instead of dangling off it, this is the in-wall replacement—a tamper-resistant 15A duplex that works with Alexa, Google, and Apple Home and Siri. Pair it with Leviton's wire-free Anywhere switches for proper 3-way control. The honest part: this is a hardwired install needing a neutral wire, so it's a screwdriver-and-breaker job, not a plug-and-play module.

The cheapest way to make a dumb mini-split, window, or portable AC act like a Nest. It learns your unit's infrared remote, then adds Wi-Fi scheduling and geofencing so the room is cool when you walk in and off when you leave. Works with Alexa, Google, and Siri. Two caveats: it only works with AC units that have an IR remote, and its temperature reading comes from the controller's spot on the wall rather than across the room.

A dog camera built around the thing owners actually want—to check in and interact, not just watch. The lens motors a full 360 degrees with color night vision, it tosses a treat on command, and two-way audio plus barking alerts let you talk your dog down from across town. The catch is the subscription: the AI smart alerts and recorded video history live behind a paid Furbo Nanny plan, and the base cam works without them.

A cheap, genuinely accurate room monitor built on a Swiss Sensirion sensor good to about ±0.36°F, with a big clear LCD and on-board logging you can export to CSV—the kind of data that settles arguments about whether the nursery is too dry. It runs up to two years on a coin cell. The catch: standalone it's Bluetooth-range only; remote alerts and voice control need a SwitchBot Hub.

The most complete air monitor most homes can buy—seven sensors including radon, PM2.5, CO2, VOCs, humidity, and pressure, all cable-free on battery with Wi-Fi sync and an e-ink display you can read at a glance. It's the device that tells you whether your bedroom air is actually making you sleep worse. Two notes: it's a premium price, and radon needs weeks of data before its reading is trustworthy.

A sensible two-fixture starting point for LIFX color. This pair of A19 bulbs covers full RGBW with tunable white from a warm 2700K to a crisp 6500K and 800 lumens of comfortable, true-to-life light, with CRI 90 keeping every shade accurate whether you're working or winding down. The LIFX app brings 200-plus themes, custom palettes, gradients, saved scenes, schedules, music sync, and 1–100% dimming with no wall dimmer needed. Best part for getting started: no hub or bridge required — screw in, scan the QR code for instant HomeKit pairing via Matter, and they also work with Alexa, Google Home, and SmartThings. Setup runs under five minutes per bulb.

A two-in-one alarm that puts a smoke and CO warning on your phone whether you're upstairs or out of state—photoelectric smoke sensing paired with an electrochemical CO sensor in one battery-powered unit, no hardwiring or hub. It's the simplest way to make an existing home's safety net smart. Two caveats: the app alerts lean on a stable 2.4GHz connection, and it won't interconnect with older non-smart alarms.

The newest Ring Indoor Cam Plus is the one to get when picture quality matters indoors. Retinal 2K video with 4x zoom catches detail across the room, and the imaging handles tough lighting well — balancing bright windows against dark corners, holding true color in low light, then switching to crisp black-and-white in the dark. You get real-time motion alerts plus Live View and two-way talk to respond on the spot. The standout for a bedroom is the sliding lens cover that physically blocks the camera; just note the microphone stays on when covered and must be disabled separately in the app. History features lean on a Ring Protect plan.

Blink's most affordable wireless camera, and the value play is real: up to two years on the included Energizer lithium AAs means you're not on a charging treadmill. You get 1080p live view, infrared night vision, two-way audio, and dual-zone motion detection through the app, plus a five-camera kit with a Sync Module Core to cover a property cheaply. Two caveats to go in clear-eyed: the Core has no local storage, so footage lives in the cloud on a Blink subscription after the 30-day trial, and person detection is a paid feature too. Add a Sync Module XR or 2 to store clips yourself. Works with Alexa.

The smart display that earns the kitchen counter: an 8" screen big enough to actually follow a recipe or hold a video call on, small enough not to dominate. The auto-framing camera keeps you centered, and the built-in Zigbee/Matter/Thread hub means it doubles as the brain for your lights and locks — no separate bridge. Best for someone bought into Alexa who wants one device to run the room. The catch: it's Alexa-first, so a Google or Apple house should look elsewhere.

A genuinely cheap plug that does something most don't—reports real-time, per-device energy use so you can find the space heater or old fridge quietly running up the bill. It does the usual scheduling and timers, works with Alexa and Google, and feeds into Emporia's wider whole-home energy ecosystem. Limits: single outlet, 2.4GHz only, the data lives in Emporia's app, and there's no Matter or HomeKit.

For people who don't want their door to look smart at all. Level hides the entire mechanism inside the deadbolt—from the hallway it reads as an ordinary lock—while quietly carrying Apple home key, so you tap your iPhone or Watch to get in like tapping to pay. Matter over Thread connects it across Apple, Google, Alexa, and SmartThings, and the 15-minute screwdriver install fits standard doors. The catch: that invisibility costs more than bulkier rivals, there's no keypad in the box, and it leans hardest into the Apple world. If design is the deciding factor, nothing else is this clean.

The Sensi is the sensible budget thermostat: it skips the touchscreen and color graphics and puts the money into what actually saves energy. ENERGY STAR certified, it leans on flexible scheduling, remote access, and usage reports to trim HVAC energy by about 23%. Installation is unusually DIY-friendly, with a built-in level, step-by-step app guidance, and no c-wire required in most homes, and because it fits the footprint of a traditional thermostat with real buttons, you won't be patching and painting the wall. It also nudges you with maintenance reminders like filter changes. Emerson's privacy stance is a bonus: it won't sell your personal information.
