They are easy to install, they fit nicely in the J-boxes, they look nice once the switch plate goes on, they connect quickly and easily to the home's Wifi via Martin Jerry's SmartLife app -- and, as an added bonus, the app even remembers all the details of your WiFi setup, and pre-fills everything in (including the password) when go to set up another switch. And if the WiFi signal at the switch is weak, the app offers two 'fallback' methods of connecting the switch (the first one, "default installation," worked for me on the first try). Integration with Google Home is a breeze -- and each new switch that I add (after the first one) automatically shows up in Google Home The only way they could make this any easier would be if they came to my home and installed the things for me.So far, I've installed SPST ("single pole") switches, dimmer switches, 3-way dinner switches, and 4-way dimmer switches -- more than two dozen switches so far (and counting). All work great. I recently installed LED bulbs throughout the home (we just purchased it); the LED bulbs were flickering with the old Lutron dimmer switches -- but once I installed the Martin Jerrys, NO MORE FLICKER!I'd give these switches 6 stars if I could.One request for Martin Jerry, if they're paying attention: A 3-way SPST switch would really help "round out" your line. And a single-gang DPST switch would be nice, too (two switches in a single stack; to keep it easy, just have a single hot and a single neutral, with each switch controlling one load -- and the ability in the app to control the two switches independently. ### ⭐⭐⭐⭐ Nice switches but difficult install *by P***N on Reviewed in the United States on September 13, 2020* These work pretty well, they use the same Smart Life app as many of my other switches and outlets. I had to pair them a little differently, had to autodiscover the type instead of manually selecting the switch type.They don't dim my lights as much as I hoped, I have the same bulbs using a traditional dimmer and it goes darker. But, no flickering at least, maybe I will try different bulbs.Install was difficult. I have worked my way through other smart switches before but am not an electrician, and the fact that the switch connections didn't clearly match the same number or type of connections on my existing switches kind of messed me up. I found a great video on YouTube, though, which helped me understand. Basically, you need to find your main hot wire where power comes from constantly, that is where the 4 way switch goes with all the wires. Then pick colors to match up for the transfer lines, and make sure you match those same colors to the same color wire on the switches for all of the switches. For the middle switch, the one with four wires (2 pairs of matching colors), tie the matching pair of colors with the same color used on the primary switch (mine ended up being 2 reds from my old switch, plus the red to my new switch, and two whites tied to the brown wire on my switch). Finally, on the last switch, match the colors the same as the first two, but also add the load wire to the 2nd transfer cable. That will be marked on the switch as "Load". That cable will usually be black. ### ⭐ This was not a 4-way switch! *by Q***N on Reviewed in the United States on November 18, 2019* I went to install this 4 way switch and it only came with a 3-way master switch. This product is either labeled wrong, or I ended up with the wrong thing. I got 3 switches, but none of them are a 4-way product. I can't find how to actually contact them on here, but I am hoping to get this resolved at some point. --- ## 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.tn/products/124438535-4-way-smart-switch-dimmer-by-martin-jerry-smartlife-app](https://www.desertcart.tn/products/124438535-4-way-smart-switch-dimmer-by-martin-jerry-smartlife-app) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-05-22*
