SONOFF MINIR4M Matter Smart Switch, 2 Way Smart Switch, WiFi Wall Switch, Support Matter Protocol, Voice Control 4 Piece Compatible with Alexa/Google Home/Home Assistant, 2400W/10A - 4 PCS

Now my lights at home are smart.

HomeKit compatible thanks to Matter. Scanned the QR code and added it right into Home app with no issues at all. I bought two. One is in a box tucked away so far that I thought it would never connect to the wifi. Wrong. It stays connected and is reliably controlling the lights. The other one is in my normal box behind the switch. You WILL need a neutral wire at this device to power it. Just a note on the wiring diagram. The two Neutral connections are common to each other, so where the diagram shows the bulb connected to a N terminal, this is not necessary. Why? Because one side of your bulb is already wired to the neutral in your house and this is the same neutral connected to this device. So only 4 wires are needed. 2 for power (Hot & Neutral), and 2 for the control. For the control, just clip the wire going from your switch to the bulb. The switch side goes to "S2" and the side going to the bulb connects to "L Out". That's it. Another version of the wiring diagram shows the switch circuit between S1 and S2. However, in most normal 3-way situations, this will be difficult since the other wire is in the other box. No matter! The S1 connection is common to "L In". In other words, just wire the output of the switch circuit to S2 because the other side of the switch is already connected to the exact same source that is powering S1 and "L In". The diagram I attached shows how I have mine working in the most simplified way. Even though this connects directly to HomeKit, or whatever, as a new Matter device, also take the time to install their eWeLink app. You will get a ton of nice features and options. Out of the box, the switch simply toggles the state of this relay. However, you have two other modes you can select. One will "follow" the switch circuit, so if the switch is turned ON, this turns on, and if the switch is turned OFF, this turns off. This is annoying because if you use automation to control the relay, you could have to flip the switch twice to get it back in sync. Again, this is not the standard default mode. The third mode will allow you to use a momentary contact to toggle this relay. So instead of changing a switch position and holding it there, a push button will flip this contact to the other state. There are a few other interesting configurations you may never need but nice to know about. You can set whether you want to restore to the last state, ON, or OFF, after a power outage. Finally, you can manually edit the wifi settings, plus a few other things.

Funciona muy bien. Controlo una bomba de agua de 5 amperes. Es fácil de configurar y de conectar con Alexa. La conexión a internet es muy estable.

Only gripe is that they don’t have a dimmer function.

I bought a pack of 4 and mounted them inside metal junction boxes hoping they would work..and they all did. I wanted to tie all of my basement lights into one group and still have flexibility to turn on/off individual lights. They all joined my Homekit network and automations work perfectly. I like the ability to use with a switch or without. I look forward to a 2 channel version.

Its early days but so far so positive - i have tried quite a variety of brands of smart switch modules including zigbee, z-wave etc but so far these have been most effective for me as i largely use them to control things that are quite far away and for outside electrical circuits and dont wish to 'build a mesh' of hundreds of things in order to reach them. Hence the matter over wifi worked really well for me with an esblished and far reaching wifi network it meant i could deploy them far away and get reliable, consistent operation. The reduced data and control points negative from using Matter did not bother me in my use case as i just want remote voice activation for on/off and automation routines for on/off which it does perfectly and reliably. I like the volt-free contacts for adding a local switch also. They were really easy to setup using multiple control systems that are Matter compatible too. The only thing I continue to monitor is their physical longevity - the quality of the contacts is not terrible but is inferior to most other brands I have used - multiple screwing/unscrewing of terminals I suspect present issues sooner than others I have used as they are quite flimsy - but if you are careful this should not be too much of an issue.
