As someone steadily expanding his smart home setup, I ordered this Huacaoe EWeLink relay out of curiosity — and because I’ve got a background that makes this kind of DIY stuff more fun than frustrating. But for the average person expecting a “smart plug” experience, this will be a lot to handle.First off, this is NOT a smart plug, it’s a smart relay switch — essentially a dry contact device that can open or close a circuit via Wi-Fi or Bluetooth, controlled by the eWeLink or Smart Life app. You can run it on USB 5V (which I used for testing on my workbench), or wire it into a 7–32V AC/DC power supply.The two operation modes — self-locking (on/off toggle) and momentary (push-button) — are handy depending on what you're trying to control. I wired it into an old gate switch I had lying around, and in that context, it worked exactly as advertised. Setup via Bluetooth was smoother than I expected, especially after my experience with a different brand's smart switch that required stripping wires and using a jeweler’s screwdriver to anchor leads the size of spaghetti.The good:Solid build and compact design, small enough to fit inside a junction box or next to one using double sided tape.Bluetooth pairing is a nice fallback if your Wi-Fi is spottyIntegration with Smart Life and Alexa is a plusGreat for garage doors, gates, or anything else that uses momentary contactThe not-so-good:Not for beginners. If you're not comfortable with a screwdriver and low-voltage wiring, this isn’t your entry point into smart home automation.No inline plug or outlet. It’s purely a control circuit — doesn’t deliver power itself.The instructions could be clearer, especially for new users trying to figure out how and why to wire it a certain way.I’m giving it 4 stars because it works well — once you know what it does and how to use it. But unless you’ve got a specific low-voltage project in mind and don’t mind a little hands-on work, you might be better off with a smart plug.

The included instruction manual is shrunk down to fit the tiny box of this very small smart relay, so it's a bit hard to read without magnification.However, it connects and pairs very easily on the eWelink platform and app. It can be power via USB micro, or 85 to 250 V AC which means it can be connected to line power anywhere in the world regardless of voltage or frequency. From there the device can be added to whatever smart ecosystem you're using and make your garage door, gate, or whatever is controlled via dry contacts smart.I connected mine to my gate and can now open it remotely via phone from anywhere in the world to allow contractors, delivery drivers, etc. in after speaking with them via video. It's not Tuya, but eWelink which is Sonoff's platform. However, like Tuya and most other major platforms, this can integrate with Amazon's Alexa and Google's smart home platforms.

I was looking for another smart switch to add to my collection of Sonoffs, which are a fairly popular line of chinese smart home plugs and switches. That company makes a great smarthome platform called Ewelink which they license out to other vendors to build products for as well, apparently. This switch is 3rd party but seems to be fully compatible. That means inching, timers, schedule, triggers and all the integrations are available.It's a nicely made, compact, unit very similar to a Sonoff Basic but with dry contacts so you can use it like any old switch. This model handles universal AC input and conveniently also supports being powered by 5V from a micro USB.Quite happy with it.

I have an odd use case for this in that I'm running this between power and a 12V air horn that I have mounted on top of my office near our livestock. We have issues with coyotes & bobcats; there is also the very rare case of bear. While I believe in keeping our family and animals safe this can often be done with hazing not anything more long term. So I wired my horn through this switch, it was then picked up by the local ewelink integration I have in my Home Assistant. Using the self locking mode I was able to setup an automation to on button press, turn on the horn for 5 seconds, then turn it off. This means from the wall-panels inside the home, the home assistant apps on our devices, or talking to the home assistant voice boxes we have we're able to trigger off a blast of the airhorn anytime we notice an unwanted visitor. The switch is housed outside a plastic housing under a roof, around 20' from an access point to our network. It's been connected and running for more than a month now without dropping connection.

I got this smart switch with the aim of enhancing my home lighting setup. It was pretty straightforward to install and I liked the fact that it supports both low voltage and regular voltage, giving me flexibility. I decided to use it for my garage lights, which needed a better control system. It worked really well and connected easily to my Wi-Fi, making the setup process quick. The app integration was also smooth, allowing me to set schedules and control the lights remotely.However, the instructions could have been clearer, especially for someone not familiar with wiring. It’s not exactly a plug-and-play device, so I can see it being a bit challenging for those new to smart home tech. While it's compact and fits nicely in tight spots, the absence of any kind of power outlet means it only acts as a controller, which may not be what everyone looks for. Still, for my needs, it provided great functionality and made a significant difference in how I control my lights.Pros:- Easy installation- Smooth app integration- Flexible voltage supportCons:- Complex instructions for beginners- Not a plug-and-play device
