A great smart plug!
Onvis smart matter over thread plug: The Onvis Smart Matter over Thread Plug is a fantastic addition to any smart home, offering a seamless and reliable experience that truly lives up to its promises. As someone who has dabbled in various smart plugs over the years, I can confidently say this Onvis offering stands out from the crowd. Effortless Setup with Matter: The biggest selling point here is undoubtedly Matter compatibility. The setup process was unbelievably straightforward. Simply scan the QR code, and within seconds, the plug was recognized by my smart home hub (in my case, Apple HomeKit, but it works equally well with Google Home, Amazon Alexa, and SmartThings). No more juggling multiple apps or struggling with proprietary bridges – Matter truly simplifies everything. Thread for Rock-Solid Reliability: The integration of Thread technology is where this plug really shines in terms of performance. Unlike Wi-Fi plugs that can sometimes suffer from congestion or dropouts, Thread creates a robust, self-healing mesh network. My plug has been consistently responsive, with commands executing almost instantly. There's a noticeable improvement in speed and reliability compared to my older Wi-Fi based devices, especially when controlling it from further away. Compact and Thoughtful Design: Onvis has done a great job with the physical design. The plug is surprisingly compact, meaning it doesn't obstruct the second outlet on a standard UK double socket – a minor detail, but one that makes a big difference in practicality. The build quality feels solid and durable, suggesting it's built to last. Responsive and Feature-Rich: Beyond the core connectivity, the Onvis plug offers all the smart features you'd expect. I've been using it to control lamps, and the on/off functionality is always instant. Scheduling works flawlessly, and it integrates perfectly into my existing automations. While I haven't extensively used the power monitoring feature yet, it's a valuable addition for those looking to keep an eye on energy consumption. A Future-Proof Investment: With Matter and Thread being the future of smart home connectivity, investing in the Onvis plug feels like a truly future-proof decision. It's reassuring to know that this device will continue to be compatible and perform optimally as the smart home ecosystem evolves. Minor Quibbles (if any): Honestly, it's hard to find significant faults. If I were to nitpick, perhaps an integrated night light would be a nice touch, but that's a purely subjective desire and doesn't detract from the plug's core functionality Conclusion: The Onvis Smart Matter over Thread Plug is a genuinely impressive piece of smart home tech. It delivers on its promises of easy setup, reliable performance, and future-proof connectivity. If you're looking to expand your smart home with a plug that just works, and works brilliantly, I highly recommend the Onvis Matter over Thread Plug. It's a testament to how good smart home devices can be when they embrace open standards and robust technologies.

Smart plug
Its build quality is very good. Its easy to setup and provided instructions are pretty clear. Its faster than other Wi-Fi smart home products for faster, more stable and reliable connections. We can control the smart plug from anywhere at any time via the app, or just use simple voice commands to Amazon Alexa, Google Assistant, Siri, etc.

Ok at start, but they are prone lose connection
I initially really like this product. Good value for money, smart design, but for some reason I have found that after a couple of months they seem to lose connection and have to be deleted and re-added to the smart home. This has happened a few times and I'm not sure why. One is in the same room is the Smart hub and router, and the other is next door. Hence I would not buy these again.

Great value for money and works as expected
Worked as expected with my Home Assistant setup with my Apple Home TV acting as a thread border router. Fairly trivial to set up once you have a matter/thread network. Device seems to be a good quality and doesn't give me any concerns about plugging it in. It definitely seems to be in a good spot re: price - far less expensive than some options but not so cheaply built that it would have you worried about it handling mains! Notably, the device does not measure or record the amount of power consumed. I had wrongly assumed that the product would do this, but on reviewing the description, I can see that this was my mistake!

They Work Great and Excellent Customer Support
I’ve been using the Onvis S4 smart plugs for a while now, and they’ve been a great addition to my smart home. They’re compact and don’t block other sockets, which is really handy. Setup was super easy, and they work perfectly with my other devices. What I really love is that they support Matter and Thread. The more Thread devices I add, the better everything works together, like they’re all boosting each other’s performance. It’s cool to see how these devices form a stronger mesh network as you add more. The plugs are super responsive whether I’m using Apple HomeKit, Alexa, or Google Assistant. I had no issues with them until I ran into a problem updating one of the plugs, but Onvis customer support was amazing. They got back to me really quickly with solutions, and the issue was sorted in no time. Really impressed with their aftercare! If you’re looking to expand your smart home setup, these plugs are a solid choice. The more Thread devices you have, the better everything works together. Definitely worth it!

A very painful set-up process but rapid response once they're online
These were painful to set-up. I ended up giving up and trying again days later. Each plug took multiple (~10–15) attempts before it would connect. Once connected, I had a few issues, with 2 of the plugs not responding after being unplugged then plugged in again. Eventually they started working, but I'm a little sceptical. It's only been a few days and I haven't noticed any drop-outs yet but will keep an eye on them. Beyond this, they're compatible with multiple ecosystems thanks to Matter. I haven't used energy monitoring. The quality is fine. They're on the slightly larger side than some of the other Matter plugs available, I had to use an adapter for one of them to make it fit. There was a firmware update ready for each of these once they had been set up. The response time is near-instant when they are online Overall, it was a very frustrating set-up process to the extent that I was planning to return them. Now that they're online, they work as expected.
