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

I bought this little box without knowing for certain if it would do what I wanted it to do. I put some smart wafer lights in my kitchen ceiling, but they do not respond to my SmartThings commands if the double-pole light switch they are connected to is switched off. I was hoping the installation of this switch would remotely turn the switch on and enable the lights to still work. When I first got this thing, I chickened out of installing it in this switch because I wasn't 100% confident I understood the wiring diagram, and I wasn't even sure it would do what I wanted it to do even if it was installed properly. So it stayed unused for about 6 weeks until I got the bright idea to use it on a single-pole switch that operated a track light over the kitchen sink that predated my foray into SmartThings connectivity. I still battled my insecurities about the wiring diagram but proceeded anyway, connecting the wires as I best understood it. When I powered the circuit back on, I could tell I had done it right because every time I touched the test button on the Sonoff module, the lights went from on to off or vice versa. But after downloading the recommended app (eWeLink) on my smartphone, I could not get the module to be recognized. With SmartThings, there is compatibility with other apps, so once you get the native app to recognize the device, you can import it into SmartThings. Anyway, I tried a number of times to initialize the module so the eWeLink app could connect, but never succeeded. Finally out of desperation, I opened up my SmartThings app and initiated the Add Device command, and it recognized it almost immediately. So now I can control these track lights through SmartThings. And the wild thing is that the single-pole wall switch now behaves like a double-pole switch. If you want to turn the lights on by activating the wall switch, you simply flick the switch up if it's down, or down if it's up. The "on" and "off" label embossed on the toggle is no longer relevant.

I got this to smarten up a light switch in my old house. I tried a dedicated smart switch from the same manufacturer first, but the electrical boxes behind my light switches were physically too narrow for it to fit inside. This little relay, on the other hand, was tiny enough to fit behind my existing light switch. Installation was easy enough. Trim excess wire off of the existing wire connected to your switch, so that there is no exposed copper when you attach the wires to the relay. The live wire goes in the "Load In" terminal, the other one goes in Load Out. Then wire the relay to your existing switch with the S1 and S2 terminals. (I harvested wire from an old computer power cable for this.) This is a Zigbee relay, so you will need some sort of Zigbee coordinator/hub in order to operate it. I had no trouble connecting it to my existing Zigbee network in Home Assistant using ZHA. Once set up, you can control it either via your Zigbee network or with the old physical switch. Do your research before using this. I've been advised to not use this with inductive loads, such as fluorescent lights.

This sensor seems to work flawlessly, it connects to Home Assistant instantly as long as you have a good zigbee network in your dwelling. The wiring diagram can be a little confusing if you are not used to reading them. However most people that deal with Home Assistant can manage the install.

Small, connects quickly, worked with SmartThings *eventually*. When in tried setting it up with the smartthings app it would not read the QR code and wouldn't finish the setup. Then later I found it insralled in SmartThings not assigned to a room. Every time I tried to pair it it seemed like it wouldn't stay in pairing mode, but I think it was connecting quickly and that's why the light stopped blinking, I just couldn't see that it was connected because it didn't work with the wizard. Will easily fit behind an existing switch

For some reason, all the switches in my house are dark brown and have no neutral. Been looking to Alexify my light switches for a while now but could not find either brown switches or no-neutral alternatives until I found these. Installation in the wall was super easy and I could potentially easily fit one of these inside the box for each of the three switches in there. Pairing instructions aren't very clear and if you never used zigbee or z-wave items before, you might need some extra help. Apparently, I didn't need to download an app as my SmartThings hub easily found it and connected it to Alexa without problems. I wasn't sure how well it would work so I bought only 1 to test. However, after installation of this one, I bought 8 more! :) I might buy more soon.

After several months I finally gave up on this as a remote relay at the light switch. It disconnects from the hub and doesn’t respond to remote commands consistently. I went with a ZEN 51 instead.

The Sonoff ZBMINIL2 worked intermittently when used with two 3-way switches. Even though both switches tested working with an ohm meter. After replacing both switches I realized one of the switches was illuminated. After replacing that switch, it worked as expected. The user manual on the Sonoff website is more complete and actually readable. It shows two possible ways to wire a 3-way switch. After replacing the switch, both worked.

Ok Ill start with Sonoff is not my favorite brand. When this smart home stuff started to take off years ago I tried Sonoff devices a few times with disastrous results. Never got any of their devices to work. Fast forward 7 /8 years and I can tell you I have multiple smart home devices, its like I live on the star ship enterprise. I have had this one light that was wired with the neutral inside the ceiling box vs in the wall box behind stone tile and a scrolled ceiling with no attic space. So, without punching holes and snaking wire down to the wall box was not an option. The best option I had at the time was a smart bulb but the switch would always have to be in the on position. My wife hates Alexa so she would always use the switch to shut off the light. Thus, defeating the purpose. While recently searching for something entirely else on Amazon I came across this Sonoff mod which claimed no neutral wire is required. I decided to try it and For all technical purposes it works and seems to be working well. But there are a few things you should know. 1: The wire diagram is wrong. The diagrams show 2 options which appeared to me as a 3way or single pole options. My light was a single pole thus it’s the way I wired it at first according to there directions. This worked by voice command but the switch would not work. After studying it a little better I decided to add the extra wire from the switch to the mod and sure enough it worked. Full control by the switch as well voice control. 2: The directions are printed so small I had to take a screen shot and blow it up to read them. 3: The biggest issue was the mod would not pair with there own app, e-welink or Smartlife. This has always been the case for me with Sonoff and is why I don’t use them. I can tell you I am extremely good at it and Sonoff is so very bad at the setup/pairing process. I cant say anything about the quality of the device because it’s my first one that actually works. 4: I got it to pair directly to Alexa echo plus (zigbee) instantly when I tried it just by chance. The directions Sonoff gives did not work for me and there was no mention of using Alexa echo plus for pairing. Pros: It works. No neutral wire required. Cons: Directions are printed too small. Use your cell camara to enlarge. Wire diagram is incorrect but if you no electrical you can figure it out fairly easy. Pairing with the app they recommend to use, e-welink does not work nor did Smartlife which I was hoping would work as Smartlife is my go-to app. Use Alexa echo plus by means of discovery.

Para que funcione ser requiere un Zigbee Hub, no funciona directamente con Wifi y la app de Sonoff. Se agrega el Hub a la app y luego, se agregan los subdispositivos como este ZBMINIL2

Molto comodi per modificare l'impianto elettrico esistente e creare un impianto di illuminazione domotica. Non necessita ti tirare fili di neutro per alimentare il dispositivo. Tramite un qualsiasi server zigbee si riesce ad aggiungere punti luce domotici con comandi con i più comuni assistenti digitali (Alexa, Google home). Come serve zigbee può essere utilizzato l'eco plus e Echo show e tutti i dispositivi Alexa che hanno Zigbee integrato.

This Zigbee switch does exactly what it's supposed to do: it reliably controls the light. The installation was surprisingly straightforward. I was able to connect it to my existing wiring without any issues, and its very compact size meant it fit perfectly into my round wall box, which is about 6 cm in diameter. Out of the box, it works as a direct replacement for a standard switch, but of course, it's not "smart" on its own. This is where I hit a small snag. I wasn't initially aware that to unlock its smart features—specifically, the ability to pair it with another wireless switch or remote—you absolutely need a Zigbee hub. This crucial detail could be clearer in the product description. Once my hub arrived, the pairing and setup process through the app was quick and effortless. The ability to now control the light from multiple points and integrate it into my smart home system is fantastic. Pros: - Extremely compact – fits into small wall boxes. - Simple physical installation – works with standard wiring. - Reliable performance and fast pairing once a hub is available. Cons: - Requires a Zigbee hub for all smart functionality (not always obvious for buyers). - The included instructions could be more comprehensive and clearer.
