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

Model 30608 was shipped to me in the end of November 2020. Used tuya-convert to upgrade firmware to the open-source Tasmota firmware without any issues. I used the following template without issue: {NAME:KMC 4 Outlet,GPIO:[0,56,0,0,133,132,0,0,130,22,23,21,17],FLAG:0,BASE:36} Now I can program the outlet to turn on and then off again after fifteen minutes -- perfect for when I forget to turn off the coffee maker.

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 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.

I like the fact that you can turn off the plugs separately and not all at once

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.

I was very excited when I got this. The packaging looked nice. The app looked okay, but it was not very friendly (for example, I had to put my Wi-Fi info every time I wanted to connect. Also, there was not an actual picture of this products and I needed to choose the closest. My internet is dual 2.4GHz and 5GHz, but after many tries, I gave up. I am not sure what the issue was, but I think the internet was supposed to be only 2.4 as it said that I have to change my network setting.

I got overloaded and it worked. Good product, easy to use. I just hope it has surge protector too

I am very happy with these plugs. They are pretty reliable and work very well with Alexa. The app is also pretty handy. It lets you know power consumption statistics and has ability to create some automations. Only improvement I can think is that they don’t fit as tight as I would have accepted. But I hardly need to unplug things, so works for me.

I used to use a mechanical timer, but recently swapped to this. This product allows me to set timers with their smartphone app and monitor monthly energy usage. Great product

These randomly shut off, there doesnt appear to be a rhyme or reason to it. Otherwise theyd be great. So unfortunately you cant use them on anything where random shut offs are an issue, which is many things. Im pretty disappointed because I bought many at first thinking they were a great value, but not a great value if I have to replace them with something else.
