In case you may not know, Treatlife, Smart Life and Tuya apps can be used interchangeably. These work reliably for me for several years already, are easy to install, seem compatible with many different bulbs/LEDs, have controls to adjust indicator lights within the app, and have good WiFi connectivity. The company can be contacted for support and have even sent me a replacement when one switch was experiencing issues. Overall super happy with these. I only wish that some day there would be paddle type switches/dimmers that can support WiFi control without switching to push buttons. This is lacking across all brands, so not a knock on these. ### ⭐⭐⭐⭐⭐ Excellent product at a very reasonabe price; and great customer service *by on Reviewed in the United States January 14, 2020* I needed a handyman for unrelated projects and had him install the switch, He said it was easy and the instructions were quite clear. I already own Treatlife smart plugs so already have the Smart Life app and the Alexa Smart Life skill and integration. (That was easy to do with the earlier purchases so did not need to do it again.) . I paired the switch to the Smart Life App very easily. The instructions are quite clear and easy to follow. I then, also easily, linked the switch to the Alexa app. And I was done. I had one issue that was an Alexa problem, not a Treatlife one. I could use voice and manual controls on the Smart Life App but only manual control on the Alexa app. I worked with the Treatlife customer support first and we could not solve the problem, but the Amazon customer support figured out that the problem was a naming one that the Alexa software didn't "like". Both the Treatlife and the Amazon customer support were outstanding. The Treatlife folks followed up several times to further troubleshoot without my needing to prompt them. I wish all technical support was this excellent. Once solved, the switch works perfectly and I can easily control the lights that the switch works by voice. One of the good features of this switch is the ability to turn it on and off and dim or brighten the light manually on the wall in the event that wi-fi goes down, The wall switch also has a very dim light at its on-off point; the light is just enough to see it in the dark but not obtrusive at night in a dark room (i.e., a bedroom). Overall, quite a good product coupled with excellent customer support. ### ⭐⭐⭐⭐⭐ Connects, Works, What more can you ask for? *by on Reviewed in the United States April 4, 2021* Purchased based upon looks, price and interoperability with my existing devices (Smart Life app). I was not disappointed. Received as promised and took about an hour to do the full install and connect to the app plus Alexa integration. I use it to control my back porch string LED lights. The switch is located inside the house by the rear door and replaces the existing standard toggle switch. Here's my advice on the install; Read the product details, you do need a neutral line (white wire) for this to operate. I've read reviews that state the unit is too deep in the installation box - i did not find this to be the case here. The depth of the unit is no different than any similar smart unit device (and i have many in the house from different brands). Instructions and clear and surprisingly in full English with color diagrams to match if you are unsure (i am an Electronics Engineer and come across many poorly translated user/install guides - this one is precise). The unit (dimmer switch) comes with a standard single gang wall plate attached - my installation was into a double gang and so i simply purchased a new wall plate and detached the unit from the provided single wall plate and it fits as intended into the double gang plate. There are retainer clips on the rear (plastic) - you simply ease them open and the unit detaches from the provided wall plate. Wiring is extremely simple - the user guide even shows you how to search out your existing toggle switch to determine which is your line and which is your load wires. The product also comes with pre-printed labels that you peel off and stick to the existing load/line conductors in the wall, to be foolproof if you are a novice. Labels are also provided if you need to identify your Neutral and Ground wires but these are self-explanatory by color. Of course, labeling is optional but good practice! The unit itself is clearly marked on the rear for all four connections (Load, Line, Neutral and Ground and also by standard colors). Upon power-up the unit has a backlit LED circle on the rocker switch. When operated there is a horizontal row of small white LED's at the top to show the dimming percentage (10-100%) approximately. Connecting to the wifi was simple and occurred first time for me (unlike other brands!). Make sure your mobile phone is on a 2.4GHz network if you have Dual bands in your home (2.4 / 5 GHz) in order to complete the setup. Then simply add the device per the app instructions...(interestingly, while my Smart Life app was scanning for the device, Alexa found it first and told me it was available!). Now i can operate and dim the lights by voice command and set timers and schedule from the app etc. All in all i'm very pleased with the purchase so much so that it's making me think about other lights in my home that i have yet to change out to the smart dimmers. ## Frequently Bought Together - TREATLIFE Smart Dimmer Switch, Neutral Wire Needed, 2.4Ghz Wi-Fi Light Switch, Works with Alexa and Google Assistant, Schedule, Remote Control, FCC Listed, Single Pole (1 Pack) - TREATLIFE Smart Switch 4 Pack, 2.4Ghz Smart Light Switch WiFi Light Switch Single-Pole, Neutral Wire Required, Works with Alexa, Google Home and SmartThings, Smart Home Remote Control, FCC Listed --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/162240660-smart-dimmer-switch-neutral-wire-needed-2-4ghz-wi-fi](https://www.desertcart.co.uk/products/162240660-smart-dimmer-switch-neutral-wire-needed-2-4ghz-wi-fi) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-08-18*
