Our pick: Milfra Smart Dimmer Switch 3Gang

After personally installing and using the Milfra Smart Dimmer Switch 3-Gang (2024 New Model) for over two weeks, I can confidently say that this product brings solid performance and smart functionality to the table. I tested it in both single-pole and 3-way configurations to evaluate its stability, responsiveness, and ease of use. Below is my objective review based on real-world experience.

Pros

1. Seamless Voice Integration: The switch paired quickly with Alexa and Google Home, executing voice commands reliably. I was also able to set up Siri Shortcuts, although they are limited to pre-defined commands. The responsiveness was immediate, with no lag when issuing commands.

2. User-Friendly Digital Display: The built-in digital touch display is intuitive and surprisingly useful. It shows the dimming level clearly, and the touch sensitivity is excellent, even in low lighting. This feature sets it apart from many smart dimmers in the same price range.

3. Stable Dimming Performance: Unlike some other dimmers I've tested, the Milfra dimmer did not cause any flickering or humming, even with LED lights. It smoothly adjusts brightness levels and remembers the last setting used.

4. Versatile Installation Options: It’s compatible with single-pole, 3-way, and 4-way configurations. The included PDF installation guide is thorough and explains wiring and smart features in clear language. Even someone with moderate DIY experience can handle the setup.

5. Reliable App and Remote Control: The Smart Life app interface is clean and stable. I used it to set schedules, scenes, and remote control functions without any crashes or bugs. It integrates smoothly into a broader smart home setup.

Cons

1. Neutral Wire Required: This may limit installation in older homes where a neutral wire is not available. If your home doesn’t have a neutral wire, you’ll need to consider rewiring or look for alternative models.

2. Siri Functionality is Limited: While it technically works with Siri, its integration relies on Shortcuts rather than full HomeKit compatibility. This means you can’t create complex Siri automations natively like you can with Alexa or Google Assistant.

The Milfra Smart Dimmer Switch 3-Gang is a solid smart lighting solution, especially for users already invested in Alexa or Google Home ecosystems. It stands out with its digital display, flicker-free dimming, and flexible installation options. While it’s not a perfect fit for every home due to the neutral wire requirement and partial Siri compatibility, its performance and value make it a smart investment for most modern households.

Also great: Smart WiFi Light Switch 3 Gang

After a full week of testing the Smart WiFi Light Switch 3-Gang, I had the opportunity to evaluate its performance across multiple lighting zones in my home. The package includes three independent smart switches and a shared 3-gang wall plate, designed specifically for single-pole applications. I installed the device in a modern setting with a 2.4 GHz Wi-Fi network and a neutral wire setup. Here’s my objective take based on real-world use.

Pros

1. Highly Responsive Touch Control: The tempered glass panel responds quickly to touch with virtually no delay (around 40ms response time). The LED backlight is subtle and practical—it helps locate the switch at night without being intrusive during sleep.

2. Strong Voice Control Integration: The switch integrates smoothly with both Alexa and Google Home. Voice commands executed reliably during my testing. Whether I was upstairs or across the room, voice activation worked consistently.

3. Reliable Remote Access via Smart Life App: With the Smart Life app, I was able to control the lights from anywhere. The app interface is straightforward, and I had no issues setting up schedules for sunrise/sunset or custom bedtime routines.

4. Convenient Group and Scene Features: Creating lighting groups and custom scenes was simple. I could group all three switches together for single-tap control or include them in broader automation setups. Sharing control with family members was also seamless.

5. Sleek, Modern Design: The glass touch screen gives the switch a premium feel. Once installed, it blends well with contemporary interiors and adds a smart upgrade to any room without appearing bulky or overly tech-focused.

Cons

1. Single-Pole Only: The switch is limited to single-pole applications, which restricts its use in multi-way switch setups. If your home relies on 3-way configurations, this switch won’t work for those areas.

2. Only Supports 2.4 GHz Wi-Fi: While this is common for many smart home devices, it’s worth noting that homes with only 5 GHz networks or mesh systems without a 2.4 GHz fallback may encounter setup difficulties.

The Smart WiFi Light Switch 3-Gang delivers solid performance for homeowners looking to add smart lighting control to a single-pole setup. From responsive touch and subtle backlighting to voice command support and reliable app scheduling, it offers everything needed for a modern smart home upgrade. Just be mindful of the neutral wire requirement and Wi-Fi compatibility before purchasing.

Also great: MOES WiFi Smart Light Switch

I installed and tested the MOES WiFi Smart Light Switch (3-Gang, No Screw Panel) in a single-pole lighting setup over the course of one week. With support for Alexa, Google Home, and the Smart Life app, this switch is designed for those looking to add basic smart control without needing a separate hub. Here’s my objective review, based on real user experience.

Pros

1. Clean, Screwless Design with Mechanical Feedback: The no-screw front panel gives the MOES switch a sleek and minimal look that blends well with modern interiors. Unlike touch-sensitive glass panels, the mechanical buttons offer tactile feedback, which some users may prefer for precision and familiarity.

2. Reliable Voice and App Control: Voice control through Alexa and Google Home worked flawlessly. Whether I issued commands from across the room or via the Smart Life app while away from home, the lights responded quickly. There was no noticeable delay in execution.

3. Easy Installation (with Neutral Wire): Installation was straightforward thanks to clear instructions and labeled terminals. The wall plate supports multiple gang configurations, making it a good fit for replacing existing 1/2/3-gang switches. However, a neutral wire is required.

4. Useful Scheduling and Automation: I used the built-in 7-day scheduler to automate lighting for morning and evening routines. The timer feature and real-time monitoring worked as expected, and the app made it easy to set up without needing third-party services or additional hubs.

5. Family Sharing and Multi-Device Control: Sharing control access with family members was simple. Each person could operate the switch via the Smart Life app on their own devices. I also appreciated that one phone could manage multiple switches across rooms.

Cons

1. Single-Pole Use Only: The MOES switch does not support 3-way or dimmer functionality, which limits its installation to single-pole setups only. This is a common limitation among budget smart switches but is worth noting for homes with complex lighting circuits.

2. 2.4 GHz Wi-Fi Requirement: Like many Wi-Fi-based smart devices, it only works with 2.4 GHz networks. If you use a 5 GHz-only system or a mesh router without dual-band separation, initial setup could be problematic.

The MOES WiFi Smart Light Switch 3-Gang offers a reliable and affordable way to smarten up your home lighting with a no-nonsense approach. It’s ideal for users who want the mechanical feel of a traditional switch combined with modern app and voice control. While it lacks support for multi-way setups and 5 GHz Wi-Fi, the overall performance, design, and ease of use make it a strong contender in the budget smart switch category.

Are you looking to upgrade your home lighting system and make it smarter? Then you might want to consider a 3 Gang Smart Light Switch.

Whether you're looking for convenience, energy savings, or the ability to create unique lighting scenes, a 3 Gang Smart Light Switch could be just what you need. 

When it comes to choosing the best 3 Gang Smart Light Switch for your home, there are several factors to consider. First, you want to make sure the switch is compatible with your existing wiring. Some of the switches are designed to be used with an existing wiring system, while others require a whole new installation. It's important to understand the wiring requirements before making a purchase. 

Another important factor to consider is the device's compatibility with other smart home devices. If you already have a few smart home devices already installed, such as a thermostat or security system, make sure the switch is compatible with them. This will allow you to control all of your home devices from one central switch. 

Finally, you need to consider your budget. While most 3 Gang Smart Light Switches are relatively affordable, there are some that come with more features, such as dimming, multi-zone control, and voice commands. If you want to maximize your lighting experience, you may have to invest a bit more to get the features you want. 

If you're ready to make your home smarter with a 3 Gang Smart Light Switch, then you just have to decide which one is right for you.
