Who it fits
Good fit for
This dimmer suits users who want visual feedback on their lighting levels. The 1.8-inch screen is useful for verifying brightness settings without an app. It fits 3-way setups where you need smart control at one location and manual control at another.

ELEGRP Dimmer Key Specs Explained
Circuit Type: Single Pole, 3-Way
You can install this switch in a standard single-pole setup or a 3-way circuit where two switches control one light. This flexibility allows you to replace existing wall switches without rewiring the entire circuit. It suits homes with multi-location lighting control, offering a straightforward upgrade path for versatile room layouts.
Connectivity: 2.4 GHz Wi-Fi
The device connects directly to your home router using the 2.4 GHz band. You do not need a separate hub or bridge to enable smart features. Ensure your router broadcasts a 2.4 GHz signal, as it will not work on 5 GHz networks. This direct connection simplifies setup and reduces potential points of failure.
Maximum Load: 150W LED, 450W Incandescent
This rating defines the total wattage of bulbs you can connect to the switch. You can dim up to 150 watts of LED or CFL bulbs, or 450 watts of traditional incandescent bulbs. Exceeding these limits may damage the switch or cause flickering. Always sum the wattage of all connected bulbs to stay within safe operating limits.
Wiring Requirement: Neutral Required
Your electrical box must contain a neutral wire for this switch to function. Most modern homes have neutral wires in switch boxes, but older installations may not. If your box lacks a neutral, this switch will not work. Check your wiring before purchasing to avoid installation issues or the need for an electrician.
Smart Home Compatibility: Alexa, Google Home
You can control the dimmer using voice commands through Amazon Alexa or Google Assistant. This allows hands-free operation for adjusting brightness or turning lights on and off. It integrates into broader smart home routines, such as triggering lights when you enter a room. Verify your preferred voice assistant supports third-party smart switch integrations.
Hardware Design and Physical Controls
The ELEGRP rotary dimmer comes in black or white finishes to match common wall plates and interior decor. According to the listing, the switch features an ultra slim profile. This reduced depth leaves extra room inside your electrical wall box, which makes tucking in household wiring easier during installation. The front interface pairs a rotary dial with a built-in 1.8-inch TFT display screen, giving you tactile physical adjustment alongside direct visual readouts.
The physical controls center on the rotary knob, which includes customizable LED backlighting situated directly behind the dial. This backlight helps you locate the switch in the dark while creating subtle accent lighting. According to the listing, the 1.8-inch display turns on automatically when approached, offering gesture activation alongside a customizable screensaver. When active, the screen shows your brightness percentage, four clock patterns, and local weather updates. You can also press and hold the screen face to enter device settings directly at the wall.
For electrical safety, the physical construction is UL and CUL Listed as well as FCC certified. These certifications confirm that the internal components and housing adhere to verified standards when wired into standard single-pole or 3-way residential lighting setups.
