Wi-Fi Smart Switch 10A 2400W, Smart Relay Switch Works With Alexa/Google Home Assistant, Remote Control & Scheduled, Neutral and Live Wires Required, MINIR4

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

Easy to wire in and pair with zigbee on home assistant. Get a 10mm spacer from CEF for your light switch and they fit UK shallow boxes.

Used this for an outside light to come on at sunset. Would have been 5* but instructions are poor and does not work with 5Ghz, only 2.4. Like most people I have 5Ghz and 2.4Ghz enabled with the same SSID. To get the device connected you must. Go into administrator on you router Turn off 5Ghz leaving 2.4 only. Connect the device to 2.4 Go into administrator and re-enable 5Ghz. Works perfectly.

Excellent product. Works well with Alexa.

Good product works perfectly

After moving into our new home we began looking at options for lighting both indoors and outdoors. With already owning a handful of 'smart bulbs' we were not looking forward to the cost of fitting a whole house. I then stumbled across this little bit of kit. After looking into it further and contemplating more expensive alternatives I decided to give Sonoff a try and why not at such a price. I did get my electrician to install this product just to make sure everything was safe. According to them it was a straight forward fit. It was small enough to fit inside a metal clad two way light switch in my garage. I had it connected to the my outside light circuit. The device connected to the Welink app very quickly and easily. I can now control said lighting circuit from my phone. I have also connected it to Alexa. In this instance I have set a schedule for the outside lights to turn on and off at certain times. I can safely say paired with standard bulbs this is a much more cost efficient and dare I say better alternative to 'smart bulbs' unless you required RGB/remote dimming functions. I will be purchasing more of these for other areas in the home and further adding this to my home assistant setup eventually which would appear to a very simple integration. My electrician has also said that he is going to be buying one for his outside lights as he was impressed with it!

Very simple to set up and works well most of the time, but does keep becoming unresponsive. I have one of these mounted in a weatherproof junction box which powers my outside lights. It's linked to Home Assistant and every 2 or 3 weeks it becomes unresponsive and I have to turn the circuit breaker for the outside lighting circuit on and off to reset the device.

Works very well with Alexa once you enable the Ewelink skill. Placed in a group, actions can be added to turn the switch on or off by voice, by button remote or by sensor. Great value for money. Bought two of these when they were £12 each, which was oddly cheaper than buying a bundle of two. Could have bought the no-neutral version, but I needed to control these over WiFi as they are placed inside metal wall boxes, which Zigbee probably couldn't penetrate. You also need to connect to 2.4 GHz WiFi as 5 GHz is not supported and will prevent connection if you have the same SSID for both frequencies. I give my SSIDs different names for this reason.
