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 originally had high hope for this product. I received two units pack. One unit was not working out of the box. The instruction is not clear and the software did not correspond to the right product. I thought something went wrong with the software instead and spent hours doing trouble shooting. The other unit worked but was very hot when using. I dont know whether I am saving energy or waste energy at this point. Anyway I went ahead and asked for a replacement thinking it is just bad luck. What I got was a used unit and there was only one unit inside even with the label saying two unit pack. Now there is no option for replacement anymore but only refund from Amazon site. Very disappointing.

Its great that you can name and control EACH port separately via Alexa, via the KMC Smart app. You download KMC smart app and then choose the KMC Smart skill from Alexa. I bought (4) and immediately programmed two. Upon command, it will turn on 2 of three lights and not the 3rd, then the next time the 1 light and not the other two, then the next week it would do all. I kept the two because I need the outlets, but returned the other two before installing. I just wont rely on voice control for those.

This is a decent smart plug pack for the money. I have opened up the plugs and the quality inside is not the best, so I would not use these for Watt heavy equipment as this can melt. But it works great with stuff that draws less current, I would not use this to automate a space heater. The best selling point for me was the ability to flash Tasmota into this unit so I can use it with my Smartthings ecosystem. The integration was good and it showed up in my Smartthings. It also works with the Smart Life app if you dont have the Smartthings ecosystem. One thing to mention is these are not individually metered/ The first plug is the only one that will show metered and it basically sums up the usage of all 3 plugs. Also, the 4th plug is not controllable, its an always-on plug. I did notice that sometimes the unit loses its connection, and I have to unplug and plug it back in to connect to the wifi. But this has happened only a handful of times.

if you have linux around and want to flash this with better firmware, search on tasmota and tuya-convert. worst case, you open this unit and connect an ftdi serial cable and flash tasmota yourself, but doing the OTA trick sure is cool and almost fun ;) once you get open firmware on it, its WAY better. I have many of these at home and they all run the same firmware and can be remotely controlled with simple curl commands, fully scriptable, no need for gui or phone-home-china stuff. dump the factory firmware and never look back. these have the extra feature of power-mgmt (you can read voltage and current and power, for the whole unit, not on a per-port basis, sadly). see the config screen image for what the pin mapping is, for this module. each tuya module by each vendor is wired differently; so you have to search the model to know what each pin on the ESP chip does. I did that work for you, so just use this and be happy ;) again, its going to be a bit of effort to learn and read all you need to, to flash tasmota. to get this unit into program mode, you power it up then quickly hit the single power button and hold it for a long time until it flashes differently. I think it took over 10 or 20 seconds. keep pressing until it starts to blink. THEN run the tuya convert util on your linux laptop or rasp pi, DO FOLLOW THE INSTRUCTIONS and DO use your phone to connect to the ssid that the linux util says to. just connect to it like its a wifi portal and keep your phone on that. THEN proceed to flash tasmota from linux to the kmc4 unit. its complicated but worth it and once you do one, youll do the next one a lot faster and easier.

These arrived quick and were easy to set up. It said you had to get their specific app, however I already had an app that went with a power strip I bought a few months ago. I took a chance and it loaded on it. Nice to keep all my devices on one app instead of every make/model having a different app to use. Works with Alexa pretty well. All in all I’m super pleased with this purchase! Might add a few more later on.

The good is that it helped with monitoring electric usage for gauging power requirements that I needed. So it achieved what I got it for. The app was easy to use. However, the bad part is when you lose power, this defaults to OFF, and the only way to turn it ON is to hit the power button, which is a pain when it is tucked behind a server rack. I ended up removing it once I no longer needed to gauge the power usage.

Very easy to use but the outlet tends to lean a lot not a tight fit to the outlets you have to make sure it’s close to assure connection . I ck once a week to be sure that it is connected.

These are a waste of money!!! Customer service was great after I received my first set and only one worked they set me another set. All of them are out and will not run even a small fan for more then 10 minutes before they shut down and have to be reset so they are worthless to me. I suggest going with something else. Id give less then 1 star if I could.

These work but could be better

This is a good concept except two major issues. 1. It only used one socket instead of the commonly available 2. 2. It randomly starts clicking and turned off. Has happened at least 5 times.
