Why haven't I seen these sooner?
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!

Incredible size – actually fits in 47mm UK back boxes!
I’ve used previous versions of Sonoff switches, but this Mini R4 is a massive improvement just based on the size alone. It is absolutely tiny. If you live in a UK house with those annoying shallow 35mm back boxes, this will not fit, you will need 47mm and most of the house will not have neutral in the light switch, so would suggest for no neutral sonoff smart switch. I managed to tuck it behind a standard light switch with room to spare for the wires. Setup was a doddle via the eWeLink app, and it discovered the device immediately. I really like the 'detach relay' mode—it allows me to use the physical wall switch to trigger scenes without actually cutting the power to my smart bulbs. Just remember: you do need a neutral wire at the switch location for this model, so check your wiring first. Highly recommended for a stealthy smart home setup. We had issues after few months but the sonoff customer care was helpful and they helped accordingly to resolve our complaint.

Really simple piece of kit
This product was brilliant, it was small and compact. I have used this as a smart switch for my christmas lights, it has fitted to the inside of an outdoor socket. The connections were simple as you dont need to use an external switch you can just connect through the device and this will suffice. This switch is really simple to set up on the app and you can program the functionality so that when it gets power to it then it is either on or off. There is no change in light output from your assosciated equipment. The cost of this is minimal in comparison to if you use it to automatically switch something off that normally stays on. The only thing to be aware of is that this connects into the electrical wiring so as an electrician i was easily able to install safely but if your not competent working with electricity then i would advise you maybe use a plug in switch rather than this connected smart switch.

Reliable smart switch, works great with Alexa
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.

Brilliant piece of kit
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

Useful device, but not as reliable as expected
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.

Compacto, funcional y fácil de usar
Mi experiencia con este interruptor WiFi ha sido muy positiva. Cumple bien con lo esperado, permitiendo controlar luces de forma remota y mediante voz con Alexa o Google Home. Su tamaño compacto facilita la instalación en cajas pequeñas. La calidad parece adecuada para su precio y es sencillo de usar con la app eWeLink. Como consejo, es importante revisar bien las conexiones y características antes de instalar para evitar errores. En general, lo recomiendo a quien busque una solución práctica y fiable para domotizar sin complicaciones.

Interrupteur connecté
Très bien, ça fait son job, c'est très petit. Ça rentre bien dans les prises. Plus besoin de se lever pour aller éteindre la lumière Alexa le fait pour nous. Merci.
