Great value for money and works perfectly. ### ⭐⭐⭐⭐⭐ Brilliant piece of kit *by B***Y on 13 January 2026* Brilliant piece of kit! Solved my problem of not having a light switch beside bed. Very compact and fitted inside the back of the switch smoothly. Easy to wire and to connect for beginners like me. Good quality. Can’t recommend enough. Update: There’s the matter version which connects to Apple Home 10 stars ### ⭐⭐⭐⭐ Reliable smart switch, works great with Alexa *by M***M on 18 March 2026* I put this behind a lamp in the living room so I could control it with Alexa and Google Home. Setup through the eWeLink app was straightforward, took about ten minutes to get it connected to the wifi and linked to my voice assistants. It works reliably and I've had no issues with it dropping off the network. The switch itself is compact enough to fit inside the lamp base housing, which was important for keeping things tidy. I also set up a couple of schedules through the app so the lamp comes on automatically in the evening. For the price, it does exactly what you'd want a smart switch to do. Only thing I'd mention is the instructions could be a bit clearer for anyone not used to wiring, but if you've done basic electrical work before it's simple enough. ## Frequently Bought Together - SONOFF MINIR4 Smart WiFi Light Switch,Universal DIY Module for Smart Home Automation Solution,1 Pack - SONOFF MINIR4M 10A Matter Smart Switch,Universal DIY Module for Smart Home Automation Solution, Work with Alexa & Google Home,1 Pack --- ## 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.jp/products/519852775-sonoff-wi-fi-smart-switch-10a-2400w-smart-relay-switch](https://www.desertcart.jp/products/519852775-sonoff-wi-fi-smart-switch-10a-2400w-smart-relay-switch) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-05-04*
