2 Pack SONOFF ZBMINIL2 Extreme Zigbee 3.0 Smart Light Switch,Works with Alexa, SmartThings Hub, Google Home, SONOFF ZBBridge(No Neutral Required)

Great little switches

Works perfectly, I like the smaller form factor compared to the last generation Linked to my Hue hub

Funcionan muy bien! Para los que dicen que no les funciona, deben comprar un bridge que se conecta a Wi-Fi (ver foto) para poderlos utilizar.

These are not easy to figure out in terms of wiring. But, once you do, they tend to work. I was using these to add to light switched in a Church building with old wiring. They do not require a neutral, which is good. Figuring the wiring pattern was tough. In short it is: Line (to the light fixture) to Line in (1st port) (This would previously have bene on the "dumb" switch, on the screw that was not the ground (green screw) and was not the hot (you will need to determine which wire is hot (load) and which is the line Load (Hot) to Line in (2nd port) S1 - blank S2 - connects to the lightswitch (where the Line would have previously been on the light switch if it was previously set up as a traditional 2 way switch that has a Load (hot) and Line (connected to the light fixture). . The dumb switch needs a Load coming in to it (I used a wire nut to connect the load coming into the box to two other wires, one going to the Load In on the Zonoff, and one going to the top of the "dumb" switch. The other wire coming off the "dumb" switch is a Line wire that connects to the SONOFF switch instead of to the light. THEN when you turn it on, you need to do a factory reset, otherwise, the switch will only turn off about every 2-6 times you flip the manual "dumb" switch. Once I did a factory reset (held the button down for about 5 seconds) and repaired with Alexa (Alexa is my Zigbee gateway) everything worked. I would give this 4 stars, but no one reads 4 star reviews.

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.

Funcionan con mi hub de Alexa excelente!!
