SONOFF ZBMINIL2 Extreme Zigbee Smart Light Switch (2 Way), Compatible with Alexa, SmartThings Hub, Google Home&SONOFF ZBBridge-P, ZigBee Hub Required, No Neutral Required 4-Pack

These work great! They are easy to plug in. Setup is simple with SmartThings. No custom firmware needed they work right out of the box. They are small and they fit right into light switches or inside the electrical box the lights are mounted to. The way my house is wired, most of the lights have the neutral wire in the electrical box above the light fixture, so these work great without having to rewire like I would if I wanted to replace the wall switch itself with a smart switch. My only complaint is that the lights can’t be set up to use a momentary button. if you turn the light off remotely, then flip the switch to turn the light on the switch might be in the down position with the light on. Not a big problem, but a small complaint that I hope they address with the next version of these. I used the SONOFF WiFi devices for a while. My router struggled with 40 smart devices connected in addition to everything else. The switch to Zigbee takes care of that problem while simplifying setup and (ideally, I didn’t test it) using less standby power. The devices also say they work as a zigbee repeater so you might just install some if you have any problems with zigbee devices dropping offline. If they are far from your hub, this could help. I absolutely recommend them so far. I’ll update if they have any problems. So far they’ve been running for a week reliably.

Great little switches

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.

Excelente producto, fácil instalación y funciona perfecto. Considera que tienes que tener un hub, en mi caso un Echo 2da generación los detecta enseguida. Considera que este modelo es para caja de paso ya que requiere neutro para funcionar.

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.
