Magic Switch Function Works
I had been looking for a solution for a long time that would provide smart control over my lights while still keeping a fully functioning traditional wall switch. Like many UK homes I have no neutral wire at the switch and no constant live feed at the light. This is the first product I found that could do this task.Installing and setting these up was very straight forward. The only issue I had is that, with the wall switches in my house, the Sonoff wouldn’t always respond if I pressed the wall switch quickly. I suspect the interruption in power was too short (the Sonoff works on the basis that power is going to it regardless of which position the wall switch is in – it knows you’ve pressed the wall switch and want to turn the light on or off because of the brief interruption that occurs when the wall switch is pressed). I took a chance replacing my wall switches with new ones and now it’s all working flawlessly (the new wall switches I went with that work are MK Logic Plus switches).Basically, when it’s all working you can at all times control the lights using either the wall switch or the app regardless of whether the light was previously turned on or off with the app or wall switch. The Sonoff has a good reliable wifi signal. The app works even when your’re away from home and you can use it to set schedules and well as turn the lights on and off. I’ve also connected it to Alexa without issue.Overall these are great. Just be aware that they may not work with 100% of wall switches so you may have to replace your existing ones.

Decent affordable smart switch
Nifty little smart switch. Used when installing an outside light – i was able to tuck the switch into the roof space without much difficulty. Simple to install and super easy to pair with my wifi. Has worked without issue – all round decent switch and at a good price.

Makes dumb stuff smart!
I recently installed this on some down lighters I added to soffits of my garage for some external lighting, this has worked flawlessly over the last few weeks and was very simple to setup. My only comment would be the terminals for the cable were quite small and fiddly to insert 1.5mm T&E in and the screws to clamp it down felt like they would easily break, but they have held up and I’ve had no issues

Excellent unit
We bought our first one for a path light to the front.We’ve now got our 2nd one wired into the breaker for our garden lights.We can switch them on and off via our phones, share access, schedule times etc.Really good value and small enough to fit smaller units

Ich bin absolut begeistert von diesem SONOFF BASICR4 Smart Schalter! Die Installation war super einfach, und die Verbindung mit Alexa und Google Home funktionierte auf Anhieb. Der Schalter ist sehr zuverlässig und bietet eine praktische Ãberhitzungsschutzfunktion, was mir zusätzliche Sicherheit gibt. Auch die Steuerung per Smartphone ist kinderleicht und funktioniert ohne Verzögerung. Preis-Leistungs-Verhältnis top! Absolut empfehlenswert.

Very reliable within my home assistant ecosystem. Haven’t had a single problem and it does exactly what I needed for my one speed ceiling fan. I’d complain about the size not being compatible with a double gang box but it is what it is and should be hidden anyways.

Vavien anahtarlar için ideal ürün. Avizenin oraya takmanız gerekiyor, anahtarlara olmaz. Boyutu büyük geldi plastik kapaÄını çıkartıp kullandım. Güzel tavsiye edilir
