## Description

Review: 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.
Review: Great product and very good price - Used to control and out side lantern. downloaded app. no problem. lantern worked off app, so connected to Alexa, again no problem. Lantern via Alexa skill now turns on 15 minutes before sunset and off at 10.30! Fantastic value

### ⭐⭐⭐⭐ Makes dumb stuff smart!
*by N***W on 9 December 2024*

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
