KMC Smart Tap 2-Pack, 4-Outlet Smart Plug WiFi Outlet Wall Tap, Energy Monitoring, Works with Alexa and Google Home, Remote Control Your Devices from Anywhere, No Hub Required, ETL Certified, White

I mistakenly purchased 8 of these smart taps in total. The first 2 installed OK... little finicky compared to any other Tuya Smart compatible products but not the worst setup I have gone through. Everything seemed to work OK with Tuya app and with SmartLife app on both Android and iOS. Additionally the taps were useable in Home Assistant and provided individual control over 3 of 4 outlets and power monitoring detail. Since they were cheap and worked I ended up ordering 6 more over course of several days. These 8 total were added to 37 other smart devices which included 8 other different types of power monitor plugs I have accumulated over past several years. Maybe I am being too critical but with so many different devices and the easily 40 other returned devices that either didnt work or had fatal flaws I have an insane amount of data to compare against and have ended up with a pretty good testing regimen. I am sure I spend too much time messing with smart home stuff but lets just chalk it up to a hobby (or a developing addiction?) :) Here is what I ended up realizing after I put the taps in use: They do not stay connected. Not when connected to network with 50+ other devices that are stable. Not when connected individually to network with all other devices powered off and less than 5 feet from the WiFi Router. Not when moved around to different locations in the house. Best experience has been actually connected to WiFi Extender (in AP mode) rather than directly to router. The energy monitoring data is so far off it might be closer to random than terribly calibrated. The amount off is not consistent making it impossible to just offset or compensate with a standard factor. Two of the taps (1 each from different purchases) would routinely show 0.7 V and then never reset. (Both returned as defective). The other 6 all show over 130V... which I wish was true since I actually have issues with ComEd (Illinois) being able to supply 120V consistently. I have measured the same few outlets on different breakers in different areas of house to confirm. Using a kil-a-watt device and 4 different power monitor plugs from 4 different companies (using different internals)... there is less than 1V variance across the 4 other plugs and the kil-a-watt -- all showing between 116-119.5 V over long periods of time. Each of the 6 taps I have not yet returned show 127-133V. The values seem stable until a device is reset and then used again... first time might hover around 127... then after rest 131... 2nd reset... 133. Having the V read high in turn causes the power to be calculated high... somewhat defeating the purpose of collecting energy monitoring data from the tap. The taps shut off randomly... often if there is a network reset (reboot router, power outage, internet outage... etc). There is not setting to retain relay status or force on as default mode. Even a dip that does not trigger a UPS or flicker other smart plugs/taps will power off these taps. The always on outlet power use is not part of the power monitoring. If you use the 3 managed outlets you can get inaccurate power data and you have to manually button switch the device on periodically due to the random shutoffs. If you use the always on outlet no power data is measured and at that point you are just doing exact same thing as not using the tap and using the wall outlet. There is no over current protection or it exists well above what can be hit from a standard residential outlet. I have 1 outlet I know I can trip on demand with a toaster and an electric kettle. The toaster starts at 800W and levels to 750W and the kettle starts within few seconds at 1700W and settles to 1550-1600W. One in each plug is an almost immediate 2500W pull which will trip the breaker in a few minutes. Any other smart plug or tap I use will auto-shutoff before both can get to full power... except when plugged into this tap where it runs for a min then breaker trips. In fact the kettle alone shuts off most other smart taps/plugs except on marketed as heavy duty. All have same 1875W max most smart devices in US have in their specs. Last point is kinda funny as the tap wont shut off to save you but if you use it with a reasonable load (1 LED bulb lamp or a USB phone/tablet charger)... it will shut off intermittently for no reason. I will probably return these though I might also attempt to reflash the firmware and see if this is an actual hardware issue or a software/firmware issue with this company (KMC). I fully expected buying sketchy smart home devices would come with issues... but for the most part it has been easy to figure out immediately something works or not. Things that work have worked as expected until these taps. If you are afflicted with same problems I have and waste an inappropriate amount of time on smart home hacking/tinkering the price of these taps and the challenge of working around a poorly manufactured or poorly coded device might be a use case. If you want an inexpensive smart home device supported by Tuya or SmartLife app which in turn integrates with Google Home, Alexa and even Homekit (if you use Home Assistant server)... there are at least 2 other taps and 10-15 other similarly inexpensive 1 or 2 outlet plugs that wont disappoint. I am not going to tell anyone not to buy something but I did want to provide something more than the typical this sucks review for those who want to know why something is rated low by someone.

Easy to use and priced right!!

I have used a lot of different smart plugs. This was definitely on the easier side as far as set up goes and you can’t beat the price. Can control individual plugs or entire outlet with smart devices

Easy to set up and works great

These are awesome. I do not use Alexa but they work great with Google. I love them for all my indoors Christmas lights. I added them as a group in my Google Home app and can turn all on and off with one voice command.

Fairly easy to set up and works perfectly with my google home. After the initial set up it has worked perfectly and has not required any more maintenance.

These work but could be better

I got this plugs on a sale for $ 16.14 a pack, this means $8.07 per plug. Initial impressions, construction looks good, this seems to be made by KMC and not a rebrand as it regular with all todays procuts as the brand is stamped on the product and not a label. The internal looks of good design and contructions, i got this to be used on my server rack so i can turn off/on individual products in case i need to restart them , like a server or switch. My initial problem was with the claim that After a power outage, outlets will retain their most recent setting to save energy. this is currently not true with the current firmware version, i tried diferent ways and would not work this way so it will not serve my purpuse unless i put tasmota on it. You can control each individual plug on the top row, and the one on the bottom is always on as indicated. I flashed this with tuya-convert and after that i programed the relays to retain memory and stay on the last state. One aded value of this plug is that it has total power monitoring, you can measure the total consumption of all the switches and this is good if you want to monitor your devices or appliances. Another good thing is the little plastic plug on the back that is supposed to align on a US 2 outlet receptacle for added stability, however you may need to remove this if you are going to plug this into any other place like the output of a UPS like in my case. Overall, this is a great value, im taking half a star because of the claim that the relays stay on the last state, this may be corrected on a future firmware upgrade, however this is common for smart devices with a few exceptions.

Needed a timer for the Christmas lights that was easy to use & accessible through an app. So far it has worked great! It was easy to install. Would recommend !

Kind of a pain to have to clip off the plastic peg in the back. It was in the way and I couldn’t plug it in otherwise. It should be easily removable. The directions are faulty, the app they tell you to download is incorrect. The correct app is called “Smart Life”. I already had that app for some other devices I already own, so once I realized that thanks to another reviewer, it was quite simple to add this device. My other complaint is that the plugs are much too close together side-by-side. It’s very difficult to plug three things in altogether, especially since one of the items I needed to plug-in has a wider plug than most. I was able to resolve that by using a converter from two prong to three prong, even though my original plug was three prong to begin with. But it extended it out far enough that I was able to make it work. Alexa was easily able to discover the device and from that point programming was simple. Without the stupid plastic bag on the back, faulty instructions, and needing to jury rig one of the plugs in order to use all three, I would have given this five stars. If I didn’t happen to have that plug converter on hand, I would have only been able to use two of them. And even then it was pretty tight. hopefully this will get resolved in the future models.
