The Sonoff ZBMINIR2 is a fantastic hidden relay designed to convert your existing “dumb” light switches into smart ones. It’s compact enough to tuck behind a light switch, making it a seamless solution for upgrading without changing your fixtures.However, like many smart devices, it does have a caveat—you’ll need Sonoff’s own hub or bridge to unlock its full feature set. While that’s a slight drawback, the overall functionality makes it worth considering.I used two of these relays to tackle a tricky two-way switch circuit. I have a light in the loft controlled by switches at the bottom of the stairs and in the hallway, but there was no switch at the top of the stairs. Here’s how I solved it:1. I installed one ZBMINIR2 on the “pole” side of the two-way switch circuit downstairs.2. I wired another upstairs where there was an unused light switch (previously wired for outlets that had since been converted).Using the upstairs switch, I configured a “scene” to command the relay downstairs. This setup now controls the loft light without the need to run additional wiring upstairs. Even better, the upstairs switch doesn’t need to be directly connected to a load—it works perfectly with the relay via the scene setup.Initially, I tried to achieve this with the Sonoff ZBMINIL2, but since it requires a load wire to function, I would’ve needed to add a resistor between the neutral and load terminals. This workaround wasn’t ideal, as it would waste power and generate heat whenever the switch was on. Switching to the ZBMINIR2 resolved the issue entirely and allowed for a cleaner, more energy-efficient solution.In summary, the ZBMINIR2 is a reliable and versatile relay for upgrading your switches to smart functionality without major rewiring. Just keep in mind the need for Sonoff’s hub for full compatibility. It’s a great little device for creative problem-solving in home automation.

SO, what should you know about these? Well, they turn lights on and they turn lights off. It is really that simple, but there is a little more. The way they work the switch doesn't work as a traditional on/off, it is more like a three way switch. What I mean is that if you light switch is in the off position and you turn the light on via the app, when you switch the physical switch to on the light will go off. Not a biggie because I really don't ever use the physical switch for the light I am using.I do like that I was able to just add it to my Smartthings without having to use the ewelink app. Also, adding another Zigbee to my mesh is helping other devices that are further away from the Smartthings/Aeotec hub.What I didn't like....well I almost wired it up wrong! The directions were SO small I had to take a picture and enlarge it on my phone! Ok, maybe that is because I am getting old. Just make sure you understand how to hook it up before you try to hook it up. It involved finding the neutral in a box with 5 switches and then adding a neutral to go from that neutral twist to the device and then the neutral from the light to the device. Oh geez, I hope that makes sense.In short, I am happy with the buy. 4 devices for the price of one enbrighten smart switch works for me. It wasn't as easy an install, but I am okay with that. I say go for it.

The SONOFF ZigBee Smart Light Switch (ZBMINIR2) is a great option for adding smart control to your home lighting. I installed it as part of my Zigbee home automation setup, and it integrates smoothly with Alexa and Google Home.Setup was straightforward, though a neutral wire is required, so make sure your wiring supports it before purchasing. Once wired, pairing with the SONOFF Zigbee Hub was quick, and the switch responded instantly in the app. The compact design makes it easy to fit into most electrical boxes.One of the standout features is voice control compatibility. I can turn my lights on and off using Alexa without needing to reach for a switch. Automations work flawlessly, whether it’s scheduling lights or syncing with other Zigbee devices.One minor downside is that a separate Zigbee hub is required, which adds an extra step if you don’t already have one. But if you’re already using Zigbee devices, this switch fits right in.And here’s a quick joke: Why did the smart switch ace the test? Because it always had the right connections!Overall, the SONOFF ZigBee Smart Light Switch is a reliable and efficient way to add smart control to your home lighting. It’s easy to install, responsive, and works well with popular smart home systems. A great addition for Zigbee users!

Very small size, and with S1 and S2 connections you can wire the existing old analog switch in a lot of ways.

These devices work great for the switching and repeating functions. I bought 4 of these and will buy more (the kind that does not need a repeater) to make my home more convenient.
