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

With older homes with no neutral, these are the ticket! Simple to install, fit great in J-boxes. They take up much less space than an all-in-one smart switch. Home Assistant made pairing a breeze. When controlling through the HA dashboard, they are instant on or off, unlike Zwave. They are not dimmers, they are ON or OFF. No flicker when used with LED lights. The use of the existing light switch has been nice. You will have to make jumper wires to connect the physical light switch to the Sonoff controller. Since installation, I've not had any drop off the network and disappear. These will be my go-to in future installations.

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.

Es muy buen producto, muy pequeño y cabe muy bien en el hueco del apagador o contacto, es importante saber que manejan un protocolo de comunicación diferente por lo que no es detectado por el WiFi, se debe comprar un aparato adicional para que lo reconozca y pueda funcionar, busquen un bridge Zigbee o cuálquier aparato que permita el control de estos dispositivos con la tecnología Zigbee de otra forma no los podrán usar.

Need strong connection to hub. Tight fit inside with 2 switches in duplex box. A larger cu inch will make it easier.

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.
