I bought this (older version that had energy monitoring) in 2018. It not only works great, but recently I upgraded some servers to use 240v instead of 120v (use fewer power supplies) and was pleasantly surprised that this plug works for 240v as well.
Teckin SP20 Smart Plug
Auto detect never tends to work for me but manually does, plugs work as intended
I bought a 4 pack of teckin smart plugs. And one was faulty. After a few e mails and a video explaining the problem they will send me a new one. It was overall a good experience that ran smoothly.
I love being able to control my plugs with the Smart Life app. These work great and I now have a house full of them and am now adding smart switches.
