SONOFF Zigbee Smart Light Switch, No Neutral, Hub Required, 2-Way Interruptor Inteligente, Voice Control with Alexa, Google Home and SmartThings, ZBMINIL2 2 Pack

I am incredibly happy with this purchase. If you’re looking for a very small form factor to add smart capabilities to a device with no neutral wire, this is perfect. I was able to fit two of them into a single gang space with a dual rocker switch (very, very tight fit but… it worked). My specific installation was to solve two light switches from different circuits, no neutral on either, in a single gang box. There are many dual switch solutions available if both switches are on the same circuit, I have found none that work with separate circuits (and I have been looking for years). Another requirement I had was the switch needs to work with no smart connections as well - it needs to function as a dumb switch if the smart connectivity is down. My initial test worked perfectly. I used the wiring diagram from the Sonoff website for “Wiring with One External Switch Control” where the rocker switch connects S1 to S2 (not the option where S2 connects to L in). I am using Home Assistant and the Sonoff device was immediately detected from about 40 feet from the base (I often find I need to get close to the base for initial pairing) and the pairing process worked seamlessly. And the best part is, the rocker switch did exactly what I had hoped - it turned into a toggle switch (so whatever state the light is in, the switch will toggle it). I was concerned that the switch could turn into an override (e.g. if the switch is off, smart functions don’t work). I love this device and will likely use it to give smart capability to a few devices that I assumed would never be online.

I installed this with my old no-neutral light switch in under 15 minutes, and it works flawlessly with my SmartThings hub. Previously, I used Zigbee light bulbs because I couldn't replace the switch due to the lack of a neutral wire. However, those bulbs often lost connection with the hub. Since switching to this device, I haven't experienced any connection issues and can now use regular light bulbs, which are much easier to replace.

Works for the most part. Sometimes disconnects but later reconnects on own.

Easy to install, pairs without problems, really small. 5/5.

Worked perfectly to convert two switches from dumb to smart. I really like the setup of having the relay control the light, while the physical switch becomes a physical input to the relay. It means that any one in my family can still walk up the switch and control the light. While others have complained that it screws up the "up is on and down is off" muscle memory, we have so many 3 way switches in our house that we're used to just toggling switches in either direction to toggle the state. As others have mentioned, it can be a little tough to get a tight grip on the wire. It feels like the sweet spot is right at the threshold of being too loose or going too far and breaking it. So far I got both to work OK, but I don't think they'd hold up to uninstalling and reinstalling multiple times.

2 of 3 worked erratically (even turning on and off by themselves) and the third would never pair. Back to expensive smart switches.

Almost effortless addition to existing Home Assistant (ZHA) system. These are very small and can fit in limited space in switch/outlet box. Impressive due to ease of installation and very small size.

I was impressed with how small the device is and it fits well inside the outlet. I scanned the QR code with SmartThings to set it up, it didn't work. But it worked when I simply scanned nearby after putting the device in pairing mode. (hold the button for 5 seconds). Things that could be better - replace the tiny unreadable manual with QR or link to the doc. - depth of the holes for the wire could be deeper

La aplicación de eWeLink necesaria para operar este aparato deja mucho que desear en términos de seguridad e integración.

Nunca me funciono , no se vincula con ninguna aplicación!! No lo compres, o en cuanto te llegue le el código para que te des cuenta de que no sirve! Yo me tarde en instalarlo y por eso no puedo regresarlos

No funcionaron, lo intente de mil maneras instalando la aplicación en diferentes dispositivos y en diferentes sistemas operativos pero nunca los reconoció ni los logro encontrar la Aplicación. Incluso lo intenté en casas de otros compañeros pero nada. Vi tutoriales de todo tipo referente a este modelo y nada. NO LO RECOMIENDO.
