No Neutral Wire Required, SONOFF ZBMINIL2 Zigbee Smart Light Switch (2 Way), Works with Alexa, SmartThings Hub, Google Home&SONOFF ZBBridge-P, ZigBee Hub Required

Finally after years of trying, I have a smart kitchen light.I've dabbled with switches all over the place with no luck, but this little thing did the job just great.Wiring was a bit confusing just because my house seems to have old/new and DIY wiring! But at the end of the day nothing went fizz pop or bang experimenting with it resulted in it either worked or it didn't, no blown fuses.i have shallow switches so I had to get a couple of mm spacer to go around the switch but other than that no issues at all, well happy.

A little piece of magic. Tiny device, comes in a miniscule box. From opening that box to using it as a light switch in Alexa was less than 10 minutes when using an Echo 4 as a Zigbee hub. You don't need to add an additional app or service, it just gets discovered as a "plug" which you can then configure as a light. The instructions tell you to install Ewe link, but you don't need to.The device takes two wires for power and two wires for switch, but in my application (a loft light) I don't need the physical switch. The connections feel secure and the device is overall well made.I'm replacing a BroadLink light switch which needed both a hub and an internet connection. This needs neither.

The media could not be loaded. Our light switches have a live wire in and then a wire out to the light with no neutral. This works perfectly with and still allows us to use our normal light switch as a dumb switch. You connect the live in to the relay "L In" connector and the wire to the light connects to the "L Out" connector. To add your dumb switch, connect the L1 to the L1 on the switch and the L2 to the Comm on the switch.The relay will follow the status of the physical switch while also allowing use independently of the switch. This means the switch can still be operated even if there relay loses connectivity.The relay does not allow you to switch on or off while it is in pairing mode but once it is out of pairing mode you can configure it for use via your Zigbee Hub and app or by pressing the physical button on the Relay.The relay is quite loud when clicking on and off and there is understandably a noticeable split second delay when using it.I'm terms of size they are no bigger than a £2 coin but my back boxes are only 16mm deep so they would not fit behind my switches without either digging a deeper back box or buying a back box extender frame. They advise not to use them in metal back box as they reduce range but I've had no issues with this.I purchased a 2 pack, one was faulty and kept disconnecting from the zigbee hub and amazon compensated me for this.I have the relays connected to my Home Assistant server via Zigbee2MQTT and it works well. I have an automation linked to a Zigbee button so that I can use it as a secondary switch.They are a fair price but you don't save much by buying them as a bundle. You can also purchase them directly from China via a popular Chinese drop shipping site for considerably cheaper if you are willing to wait an extra week for delivery. This should be kept in mind when considering value for money

The media could not be loaded. I have connected it to the toilet light in order to run some automation such as exhauster and others. This is perfect for UK wiring system.

Was a bit rubbish as the product was faulty.

I have put these behind some of my light switches and it was very easy install.Caveats:1. Check your switches wiring before ordering! If you have neutral there, then these will not work, buy the blue-greenish ones2. The switch box should be deep enough for this to fit inside nicely without any gaps between the switch and the wall

This is a very neat solution it fitted inside the switch box (MK External switch) and connected easily to the Sonoff Zigbee hub. I now have timer and remote control via the app - which can make the lights come on at a certain time including sunset +/- but the switch also still works as a physical switch (although up/down now depends upon the state of the sonoff device.Other solutions were not as small, needed a neutral wire or allowed some "ghost" current through - this has none of these issues.

Replaced an outgoing ZWAVE unit - most my other units had a neutral wire so this was a special purchase for a one off prob..Added to HomeAssistant/Zigbee2MQTT without issue and does the job without fuss
