6 Best Dimmable Smart Plugs in 2026

The Leviton Decora Smart Dimmer Plug is the most complete plug-in dimmer in this group because it treats dimming as a real feature rather than a bolt-on. It connects over Wi-Fi without a hub, so the setup is the plug, the My Leviton app and a lamp. You can set custom fade rates, which means a lamp can ease up to full brightness instead of snapping on.

It also lets you tell the plug which bulb type is connected, which helps the dimming curve behave properly with different kinds of bulbs. Voice control works with Hey Google, Amazon Alexa and Apple Siri, a wider spread than most plugs here offer. A firmware update through the app can switch on Matter connectivity, so the plug can grow with your smart home instead of being tied to one platform.

The tradeoff is that Leviton is a single-lamp plug, so it suits one lamp at a time rather than a pair. It asks a little more of you during setup because there are bulb and fade options to learn, though none of them are required for basic use. Compared with the Tapo P135 KIT, which controls two lamps through a wireless button, the Leviton is the better choice for one favorite lamp where fade control and voice flexibility count most. Compared with the Kasa Outdoor Smart Dimmer Plug, it is meant to stay indoors rather than face weather.

The Tapo P135 KIT is built around the idea that a lamp dimmer should not make you reach for your phone. It ships as a kit with a plug and a wireless dimmer button, and the button can dim and brighten two lamps at once from anywhere in the room. The plug has an outlet on the left and an outlet on the right, so two lamps can sit on the same dimmer and move together.

The plug is Matter-certified, which lets it work with Apple Home, Alexa, Google Home and SmartThings. That is the strongest compatibility story in this lineup, and it means a household that switches assistants later will not need to replace the hardware. The listing notes that the lights connected to the two outlets must both be dimmable, so a mixed pair of one dimmable and one non-dimmable lamp is not a good fit.

Day to day, this is the pick for a living room with a matching pair of lamps beside a sofa. The tradeoff is size, since a dual-outlet kit is bulkier on a wall than a slim single plug like the Leviton. It also pairs two lamps to one level, so you cannot set them to different brightness settings. If you only want one lamp with fine-tuned fade settings, the Leviton is the simpler fit, while the Tapo wins whenever a physical button matters more than a menu.

The Kasa Outdoor Smart Dimmer Plug solves a problem the indoor models here cannot: patio string lights that need adjusting from the kitchen. It carries an IP64 rating, which protects against dust and splashes of water, and it has long-range Wi-Fi for reaching a porch or deck. It is designed exclusively for dimmable lights, so the string lights you connect must be marked as dimmable.

The Kasa app lets you group several dimmers and string lights so they respond together, and schedules can bring the lights up at dusk and bring them down later. Alexa and Google Assistant support means a voice command can lower the whole patio to a dinner glow. Setup follows the usual Kasa route of a phone and a 2.4GHz network.

Ownership is mostly about placement. An IP64 plug resists splashes, but it is not meant to sit submerged or in standing water, so keep it off the ground in a protected spot. Compared with the Leviton, which stays indoors and offers fade rates, the Kasa trades fine control for weather protection. Compared with the New One 2 Pack, which is an indoor pair, this is a single plug for the one place that needs rain-conscious hardware.

The New One 2 Pack is the straightforward choice when you want two dimmable lamps controlled for the cost of one decision. Each plug adjusts a lamp from 0% to 100% brightness, and a voice command through Alexa or Google Assistant can turn the lamp on, off or to a level you name. Setup uses the Smart Life app over a 2.4GHz network, the common route for white-label Tuya-style plugs.

The Smart Life app supports remote control, schedules and timers, so a bedroom lamp can brighten before your alarm and a living room lamp can start glowing at sunset. Two plugs in the box means each lamp gets its own independent level, which is something the dual-outlet Tapo kit cannot do. The app is serviceable rather than polished, and the company behind the plugs is not a household name like Leviton or TP-Link.

That is the real tradeoff here. You gain an independent pair at a friendly entry point, but you give up Matter, Siri and the hardware button of the Tapo P135 KIT. Compared with the Eva's Light 2 Pack, the New One leans on the Smart Life ecosystem you may already know. If a plain dimmer for two rooms is the whole brief, this one fits it without extras.

The MoesGo Smart Dimmer Plug is a lamp dimmer with a good answer to an old worry: how to make an empty house look lived in. Its app can switch a connected lamp on and off at random times, creating the impression that someone is home even when you are away. It dims from 0% to 100% and works with Alexa and Google Assistant, so the same plug serves for evening mood lighting and trips away.

The timing function lets you pair a time with a brightness level. For example, you can have a lamp come on at a gentle level at a set hour instead of jumping to full strength. No hub is required, and remote control through the app works from anywhere. It comes as a single plug or a two-pack, and the two sizes count as the same product.

The tradeoff is polish and depth. You do not get Matter, Siri or the fade-rate settings of the Leviton. Compared with the New One 2 Pack, the MoesGo has the same basic dimming range, and the difference is the focus on random scheduling that the New One listing does not promote. Choose it when security-minded lighting for travel is as important as everyday mood lighting.

The Eva's Light two-pack is a mini dimmer plug aimed at ordinary lamps with dimmable LED, CFL or halogen bulbs. The plug dims from 0% to 100% and answers to Alexa and Google Assistant, so a voice command can set a living room lamp to a low level. A dedicated Smart Dimmer Plug app lets you check on and control the lamp from anywhere, and no hub is required.

Schedules and countdown timers let you turn the lamp on and off automatically. A countdown is a handy way to fade a bedside lamp out after you have settled in, or to run a lamp for a set time and then stop. The compact body leaves room for the second outlet on a wall plate in most cases.

The downside is the same as with any lesser-known brand: the app and brand ecosystem are thinner than Kasa or Leviton, and there is no Matter or Siri. It overlaps closely with the New One 2 Pack, which also has two plugs and a 0% to 100% range, so the choice between them comes down to which app you find clearer. Neither offers the hardware button of the Tapo or the outdoor rating of the Kasa, so match your lamp location first.
