Works flawlessly.
I am not a big Aqara fan, because in the past, Iâve had problems with many of their smart devices. However, I decided to buy this plug, because it was a matter compatible. And I have to say, I am very positively impressed with it. It was easy to set up, Itâs compatible with HomeKit, and it is rocksolid when it comes to maintaining connection to my Wi-Fi. I am able to control it either from the Aqara app or HomeKit, and frankly, it works so reliably, that I forget itâs even there. Finally, I like that. It is small enough that it can be plugged into the wall, without hogging the space of both outlets, which has always been tremendously, annoying to me.

Works great, but instruction included sucked.
This will product WILL turn OFF a âtouch lampâ, however it will NOT be able to turn it ON.Turns out this is not the products fault.I tried this over and over WITH the smart plug and you tubed it, thinking I did something wrong.Then I googled it and âRedditâ made it make sense:âAll a smart plug does is cut and restore power, like a localized power outage. Your lamp turns off with it because you cut the power. Does the same lamp turn itself back on after a power outage if it was on when the power went out? If not, no smart plug will change that.âSo to be sure I tried this with my lamp (touch lamp).WITHOUT the smart plug I turns the lamp on by touching it and while on I unplugged it.When I plugged it in it did not turn on how I left it.However I did the same with living room floor lamp WITHOUT the smart plug, except this it has a regular knob you twist. I turned it on using the knob and unplugged it, when I plugged it back in the light was on.Then I USED the smart plug on the floor lamp and the smart plug did work on AND off.So yeah great for OFF only when using touch lamps.Great for ON/OFF with regular lamps.I was fine with this since I bought this to turn off a night stand lamp at a certain time because Iâve been falling asleep with it on.Getting it to the correct time zone for automations to work was a pain to find, there were no instructions with the product.On that note also wish the instructions told you it wouldnât turn a smart lamp on.Below is how I fixed the time zone, may change in an app update though:In the Aqara app select âprofileâ at the bottom, then select âhome managementâ at the top, then select âmy homeâ, next select âhome locationâ at the bottom. Make sure âadjust DST automaticallyâ is toggled on.Now it turns of at the time I scheduled/automated it for. Yay!

They work great.
I tried two other supposed âMatter compatibleâ outlets for my Home Assistant system. They were both highly unreliable complete failures. These Aqara outlets require a hub. More money, but they work flawlessly. Do yourself a favor and spend the money to avoid the frustration of unreliable âsmartâ outlets.

Working well as a repeater
I bought this for only one reason – to extend my Aqara Zigbee range, and for that it works well. If you are looking for smart plugs, there are better, cheaper, and more functional alternatives out there.I had added an Aqara Door and Window sensor to our curbside mailbox and set up a “You’ve got mail!” routine in Alexa to let us know when the mail had arrived. After initially pairing with my Aqara M2 hub and working successfully for a few days, the door and window sensor’s signal strength deteriorated to poor, and then eventually went offline completely. Subsequent re-pairings yielded the same pattern – connected poorly for a few days and then went offline.Having read that Aqara’s wall switches with neutral acted as repeaters for their devices, I swapped out a TP-Link Kasa switch in our garage (the garage being an intermediate point between the M2 hub and the mailbox), only to find that the Aqara switch in the garage at best gets a “fair” signal, and doesn’t seem to be recognized at all by the door and window sensor as a repeater, so no go on the wall switch solving my problem.I then purchased this smart plug, figuring the flexibility of being able to plug it into a variety of outlets to see where it would best extend the signal was an advantage over having to hard wire switches in locations that may or may not work (and there are more outlets than wall switches). I ended up plugging it in to an outlet on an exterior wall nearest the outdoor mailbox.Initial results were disappointing – the door and window sensor in the mail box initially paired and reported an “Excellent” Zigbee signal, but then again deteriorated to poor and then went offline. It took several re-pairings of the door and window sensor until it established a steady “Excellent” Zigbee signal, with the result being that the “You’ve got mail!” routine is working consistently now.So I’d say if you buy this plug to extend your Aqara Zigbee coverage, give it a few days and perhaps a couple re-pairings to finally get stubborn devices to recognize and use the plug as an intermediate signal booster.

Decent WiFi plug control
These have been a life saver in my new house. All my bed rooms are on the same electric circuit so come summer time we can only have one AC on at a time. This was tough with young ones with hot nights. Ended up using these plugs, and they worked great controlling three different ACs so we can cycle through them. Currently I am using them for my under cabinetLights on a schedule. They perform flawlessly.

You know, buying a smart plug shouldn’t be a stress-inducing experience, but here we are. I decided to get the Aqara Smart Plug because, well, I needed another gadget to complicate my life. It’s like inviting a little piece of technology to criticize my energy consumption and judge my electrical outlets. So let’s dive in and see what this thing is all about.Positive Highlights:First off, let me tell you, the setup was surprisingly easy. I didn’t have to curse once. You plug it in, it lights up, and voilà ! You’re halfway to feeling like Tony Stark. It works great with the Aqara hub, and it integrates seamlessly with HomeKit. It’s almost like they want you to have a good experience. The energy monitoring feature is a nice touch, too. Now I can obsess over every watt my toaster consumes. Plus, the Zigbee 3.0 protocol means it’s reliable and doesnât drop the connection every five minutes like some other gadgets Iâve used. And speaking of reliability, itâs got overload protection, so I can sleep at night without worrying about an electrical fire starting because I wanted my coffee maker on a timer.Constructive Criticisms:But let’s not get carried away. The plug is a bit on the chunky side. It’s like they modeled it after a brick. Good luck fitting two of these next to each other in a standard outlet. And speaking of outlets, what’s the deal with the design? You try to plug in something polarized, and it just laughs at you. Itâs as if they think we all live in some kind of parallel universe where non-polarized plugs still exist. Also, the pairing process can be a bit of a nightmare. It took me a few tries to get it right, and I found myself questioning my life choices more than once. But hey, once it’s paired, it works like a charm.Conclusion:In the grand scheme of things, the Aqara Smart Plug is a solid addition to your smart home setup. Itâs got some quirksâlike everything in lifeâbut the benefits far outweigh the minor annoyances. I gave this a 4 out of 5 because, despite its bulk and initial setup drama, it performs reliably and offers great features at a reasonable price. Just remember, individual experiences may vary, and some lucky folks might not encounter the same issues at all. But let’s be real, if you’re as neurotic as I am, you’re prepared for a little bit of drama in exchange for a smarter home.So, go ahead, get one. Just be ready to argue with an inanimate object for a few minutes. Itâs all part of the charm.

How did you manage to make such a bad product despite you have a specific HUB to have a reliable connection??? HOW? I don’t even where to start it from:1. No matter what you do you can’t make these things working through Homekit (yes I have HUB, in fact I have 2)2. No matter what plugs are losing connection in the NATIVE APP and aren’t reachable3. Smart buttons don’t work and unreachable as well (neither through the app or homekit)Utter trash. I ordered different devices for almost $600 after having a very positive experience with their lock, but now I’m returning it all. It is unusable rubbish that shouldn’t be sold on Amazon.Update: with the latest software update it suddenly became incredibly reliable. Good job, changed 1 to 5 stars ð
