Good evening. It’s still Prime Day. Maybe we’ll be stuck in Prime Day forever (jkjk, there are only a few hours left). Since we’re here, please enjoy these deals on smart home devices. They are for sale. Please. Amazon Prime Day 2023, day two.

There are some pretty good deals on robot vacuums and smart bulbs and so forth. Got a couple of cameras in here, a video doorbell or two. Smart locks. The Google Nest Wifi Pro mesh router thing that looks like it has a candy coating, which I regret to inform you is just plastic. The new Nanoleaf Matter bulbs are on sale! They’re pretty. Other deals occur as well. But they’ll end, as all things eventually do.

Before you buy any smart home device, make sure it works with the smart home platforms and the phone ecosystems you already use. Matter makes this easier — kind of, but also kind of not. There’s also a lot of junk out there! Here’s some stuff that’s actually worth buying.

Robot vacuums

Here’s the thing: robot vacuums are always on sale, and Prime Day isn’t necessarily the best time to buy one. In fact, the iRobot Roomba J7 Plus, our favorite robot vacuum, is slightly more expensive on Prime Day than it was just a few weeks ago, while the regular J7 is down from $599 to $399 — but it hits that price every few weeks. That said, these deals ain’t bad:

• The iRobot Roomba i4 EVO, a slight upgrade to our budget robot vacuum pick, is down to $199.99 at Amazon from an MSRP of $399.99. Pretty good!
• The Roborock Q Revo, our new favorite midrange vacuum / mop hybrid, is $699.99, $200 off list and $100 off the regular sale price. It does everything well but doesn’t have AI obstacle avoidance, which will run you about $300 more right now.
• The Roborock S7 MaxV Ultra is a top-of-the-line self-cleaning vacuum / mop combo. It’s down to $1,059 from $1,400, as it has been for most of the month. < OOS 1:33 PM CT

Smart plugs, bulbs, and switches

• TP-Link’s Matter-compatible Tapo Smart Plug Mini is $11.99 when you clip the on-page coupon $13.99, from $19.99; a three-pack will run you $39.99 with the deal and an on-page $5 coupon.
• The Tapo L930-5 smart light strip is $36.99, down from $49.99 (read our review).
• Nanoleaf’s Matter Essentials bulbs and some panels are 20 percent off, putting the A19 bulbs at $15.99 a pop or $39.99 for a three-pack. The BR30s are also $39.99 for three.
• A bunch of Philips Hue lights are on sale, including this four-pack of downlights plus a Tap Dial for $168. (Update: shipping in August, but if you need downlights in August, you could do worse) The downlights are normally $185, and the Tap Dial is $49.99 by itself.
• You can also get a Hue white and color ambiance starter kit with three 75W-equivalent bulbs, the Hue Bridge, and a remote for $125.99 (from $179.99). This is the one I (Nathan) would get; the 60W-equivalent bulbs are a little dim for my taste.

Doorbell cameras

The Nest Doorbell Wired (second gen) is the best video doorbell camera for most people, especially if you use Google Home or Amazon Alexa. It has 24/7 recording and reliable alerts, and it’s down to $149.99 from $179.99.

Other good video doorbell options:

• $100 off the battery-powered Eufy Dual plus HomeBase hub ($159.99, down from $259.99). It has two cameras — one for faces, one for doorstep package alerts — and it doesn’t require a monthly fee for alerts or video storage.
• The Arlo Essential wired video doorbell is also down $100 to $49.99. We like this one because it works with all the smart home platforms. It’s worth considering if you already have other Arlo cameras. The wireless version is also on sale, but we don’t really like it. You can do better.

Smart locks

• The fourth-gen August Wi-Fi Smart Lock, our favorite retrofit smart lock, is down to $180.49 with an included keypad. It usually goes for $230 without the keypad or $269 with.

Other smart home deals

• The Google Nest Thermostat, one of the only thermostats that support Matter, is $84.99, down from $129.99.
• The Arlo Pro 3 Floodlight Camera, our favorite battery-powered floodlight camera, is down to $169.99 ($80 off).
• Get a two-pack of Google Nest Wifi Pro routers for $80 off ($219.99, from $299.99)
• A bunch of Leviton Decora Wi-Fi switches, dimmers, motion sensors, and smart plugs are on sale. Leviton says they’ll get a Matter update soon.
• The Wemo Stage Scene Controller with Thread is $34.15 $33.63, down from $49.99. Pretty good price for an Apple Home scene controller! Unfortunately, this thing isn’t going to get Matter, so it’s really only useful if you’re in an Apple Home home. Read our review!
