SONOFF MINIR2 WiFi Smart Relay Switch, 2 Way Smart Wall Light Switch, 10A/2200W, Works with Alexa/Google Home, APP Remote/Voice Control, Timer Function, Support LAN Control, No Hub Required

I spent some time researching devices that would allow control of our lights but kept coming up against the blocker of needing a Neutral wire at the switch. I wasn't expecting to find a device like this and for such a small cost. Although a Neutral connection is still required for this device, it's so small that I could put it up into the ceiling rose neatly and out of sight.Installation was a breeze and took about 5mins. Just watch the labeling of the connections. Live is well labeled but the Neutral side shows 2x NIn terminals. These are in fact pass-through so you can power the device through the first NIn and the Neutral to the load passes out through the second NIn. You can see they're bridged on the underside of the PCB.There are another 2 terminals called S1 and S2 that a switch can be attached to for manual control of the device but don't connect any live source to those terminals as they're only for attaching a switch to close the connection between them.The eWe app to set up the device is fine, but the integration to Alexa was seamless. All in all a great little device for a remarkably low cost!

Good productEasy to install and set up using the app

Great WIFI relays.Very easy to use and the addition of DIY mode is great, allows me to easy and them to me Home Assistant/Home Lab to allow cameras to turn the relays on and off.

Had to work quite hard to figure out that the control circuit had to be reconfigured to low voltage. This may be exactly what others want, especially on a new installation, but I needed a module that could just replace a switch in the original configuration. I did find one elsewhere, which allowed me to do that, and so I’m afraid this just had to go back in my case. Seemed well constructed etc, just not for me on this occasion.

ALL HAIL SONOFF!!These guys have been changing the way we think about smart homes for a while now and they've knocked it out the park with this one. They've taken one of their smart relays and added the terminals for a manual switch. Just perfect. Not only that, its super freekin small.I've been looking at getting the WiFi enabled wall switches for a while but I've always had a problem with no neutral wires at the switch, A problem for most UK households. This is where the 'Smart WiFi Switch Mini' comes into play. This little geeza is small enough to install above the ceiling rose and with some basic household electrical knowledge, some chock blocks or wagos and a spare 30 mins I was able to add Alexa capabilities to my kitchen lights without loosing the manual switch on the wall.Now no matter the position of the rocker switch on the wall, I can ask Alexa to turn my lights on or off whilst still being able to use the switch as normal, Just like any two way switch.Just Perfect!

Brilliant project item!Small and easy to set up in your ceiling rose;I have flashed a custom written Firmware to this device as the EWeLink App is more restrictive than my Home System likes, that proved difficult due to the TX/RX pins being a small solder pad not a pin but works a treat!No issues so far!Will be buying more for the rest of my lights- Note: if flashing custom Firmware, the board requires ESP8266 not ESP8285 firmware otherwise the WiFi doesn’t work (although it’s an ESP8285 installed)

I wired this into a 3 way switching circuit on my landing. Easy to connect (understanding multi switching would really be needed)! Only 1 mini needed and all original switches work perfectly. I have new wiring so neutral and permanent live are at light switch so mini fitted in dry lining box. If you have older wiring where neutral and live are at ceiling rose the mini can be tucked in ceiling behind rose. If back box is not so deep or you need to fit in 2 mini’s in a 2 gang switch you may have to conceal elsewhere (ie behind plasterboard). All considered good product and good price.Update:After further use I found that the switch connection periodically had s time delay, and sometimes the light either stayed on or off and did not recognise the change, I had 3 off these and problem occurred on each... WiFi side of it fine but this let it down.

I have used these for lighting at 240V and for LED drivers and like them.The setup is not as slick as the Meross switches, but once setup they are more reliable.NB you might need to adjust your network settings to find the switches during setup, but they can go back once done.
