SONOFFMINIR4M 10A Matter Smart Switch,Universal DIY Module for Smart Home Automation Solution, Work with Alexa & Google Home,1 Pack

Nice and small. Allowed me to drop behind a spot light on the side of the house for a fix. Detail... I have a triple led light on one side of our home. It faces a side parking area as we are on a corner and have a main drive and a side drive. The side drive is DARK. We bought a motion light and 10 years later, it stopped. I have moved to home automation and have used another brand but chose this as the size is smaller than the other. I opened up the light, pulled out the motion sensor and put this Sonoff switch in. I was about to close up the light - with this inside. Programed it to switch on at specific times using the video camera mounted on the side of the house. The camera has a motion sensor that is visible to the smart home. So, it is set to run when either my wife or I return home after dark or when specific areas (predefined in the camera settings) receives motion. That way, unlike the normal sensor, this has select areas we "look" for motion to set off the lights.

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.

Finally, a smart module that works with HomeKit right out of the box without requiring any intermediary app. I tested the integration with one of my switches—the instructions are clear, there were no issues fitting it inside the switch box, and it connected to HomeKit within a minute. A great solution for those who don’t want to change their home’s style with new switches.

This little smart switch has a lot for it:- Very small to fit in the electrical box behind physical switches- Installation instruction were clear and easy to follow- When it's working it's really greatHowever, it doesn’t play nice with your router rebooting and is prompt to lose WiFi connection in such case.

This is so small that you gonna be surprised, fits anywhere and makes your device smart!

Works great always connected

I bought these devices to use a "smarthome" system on Amazon that had been in place for some time. For some reason the original system failed or was taken offline..One day it just stopped working. I do not know why although I was told that service restoration might be underway. I was not happy when it went offline. This was not inexpensive...and as of today only part of the system is working.

Excelente, cumple con mis espectativas
