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

This year our Christmas tree remote controlled plug bit the dust. Who wants to plug in the tree each morning? So I looked for something I could use in our smart home. This fit the bill perfectly. I plugged it in and set it all up with ease. Actually was one of the easier smart plugs I have set up. Does a great job. And you can’t beat the 2 for 18 dollars or so price. I was very impressed with the price.

Using a raspberry pi 4 I was able to flash these with tasmota in just a few minutes then integrate them with HomeAssistant with ease. No soldering needed, the are ota ready for flashing. Will definitely be buying more for myself and family for home automation using HA. Knocking off one star as it’s not the best looking wall plug out there and looks a bit cheap, just need to hide it out of sight.

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.

Tried to attach the both devices to existing wifi and smart life app. Added another brands plugs within 5 minutes while over 30 minutes of trying did not work. Ive setup 80 iot devices, so the procedure is not new. New out of box but it wont connect. The receptacles are pretty tight though, which is nice. Unfortunately will have to return.

I really love being able to monitor how much electricity Im using, and this allows you to do so from your phone. Unfortunately, it only shows total use by all three smart outlets. They arent individually metered, and the always on outlet isnt metered at all. This makes a use case would be very specific. Im using one for my computer. The monitor, audio amp, and external USB hub use the switched outlets, and the computer itself uses the always on, because it can monitor its own power usage. With this setup, I can see how much energy the entire system uses, and kill power to the amp or USB if I dont need them.

I ordered the 2-pack of the Smart multi-tap outlets, and just plugged the first one in this morning. The very first thing that I did was download a bunch of Smart Device apps, most of which were mentioned in different reviews here. 1. The KMC Smart App has a low 3-Star rating, but thats what I used to connect to the device. The instructions in the app kind of suck because you have to fail at your first attempt before it tells you that another option for attempting to pair the device is to turn on, wait 10 seconds, turn off, turn on hold the button until the light blinks fast, and then you can pair with the app. Its something like that, but dont quote me. lol 2. For giggles I tried the Smart Life app that someone in a review recommended... AND... it looks almost identical to the KMC Smart app. I wouldnt be surprised if there used to be a different KMC Smart app that earned the 3-Star rating, and the app I downloaded is now simply a customized for KMC version of Smart Life. 3. Someone complained about network security because you have to share the WiFi password with the app, but you HAVE TO do that so the app can send the password to the device. The device uses WiFi as the interface if you want to access the settings, so it needs a password. If youre concerned about security, which I am, I turned on the Guest WiFi network with access to my home network disabled, but it still has Internet access if I use any cloud services down the road. 4. Some people claim that all switchable plugs turn on and off together as one unit, which is why I state that the device is buggy. It seems to be a problem in the firmware of the device. Once I got the app connected to the device, which was annoying, I used the app to turn off the second plug. It went from green to black, and then I lost my connection because it also turned off the third plug, which was powering my router. The first plug stayed green, and never turned off, so Plug-1 is independent, and Plug-2+3 may be tied together. If the problem is that the device or the firmware, then its either the app or user error. Its probably user error in my case, but if not, then the issue may be random, so just be prepared if it is. 5. My main reason for buying this Smart Plug was to monitor the electricity usage of my home entertainment system, so take the following with a grain of salt. Anyone who has ever taken a physics or electrical engineering class should know that the measurement for power in Watts is the total after multiplying Current in Amperes to Voltage, AC or DC, doesnt matter. The app is telling me that the current draw on the 3 switchable plugs, or maybe going into the device itself from the AC outlet, is 2200 milliAmps (2.2 Amps). It also shows that the voltage varies from 119.4 to 120.4 Volts AC, and the voltage seems to be fairly accurate since the power transformer is maybe 50 feet away from my home. However, and this makes no sense to me, but the app states that the Power being consumed is 189.1 Watts. Dumb it down, and 2 times 120 doesnt equal 189, so Im confused. Considering that the majority of AC Voltage devices designed and manufactured in China use an 85 VAC to 140 VAC range in their designs, which makes sense from an engineering standpoint, I cant help but wonder if some programmer didnt set 85 as a static value when writing the code to do the power calculation. Divide 189 by 120, and you dont get 2.2, so I have no idea where the device is getting its numbers and measurements from, but if the Power calculation is wrong, then obviously the KWh measurement wont be right either. Again, I simply want to monitor the power consumption of my home entertainment system, so I took off a star because I cant find any documentation to explain why Power doesnt equal Current times Voltage. Im also using two power strips in Switchable Plug 1 and Switchable Plug 3 because the plug spacing isnt sufficiently wide enough for typical 3-prong power cord male plug ends, so having Switchable Plugs 2+3 tied together is a bit irritating, but I didnt deduct any stars since I knew from reading the reviews to expect it. Otherwise, if I can get a few years of use out of the Smart Plugs, I think they are a good value, even with all their quirks. lol

Im using this with my Raspberry pi and my two 3D printers, really nice to have Octoprint (running on the pi) toggle power between the two printers! And its also really easy to flash Tasmota without having to open it up! I used a NodeMCU ESP32 to connect to the device and flashed the device OTA.

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 !

These replaced some smart power strips that were essential to my home automation routines. Unfortunately, those crapped out after a couple years or so. Hopefully these will last longer. I much prefer that these live on the wall, plugged directly into outlet, whereas the others sat on the floor — but there are definitely advantages to the power strip type. I also like that one outlet is always on for devices that I don’t ever need/want to automate. Best of all, while my old ones made an obnoxious buzzing/whining sound, these are much quieter. (I think the old ones were quiet initially, so time will tell how these hold up in that regard.) For the price, these are tough to beat.

Plugged my power strip into the always on, my IKEA paper lamp into one of the others. It has worked flawlessly and sure beats the remote and bulky units I used to have. So I bought the KMC Smart Plugs, and theyre excellent, too. All right together in my KMC Smart app.
