programming of on/off time
total consumption in kw per day.
instantaneous consumption indication in watts.
lots of information about energy consumption.

I used it for several months to connect a heating device (infrared radiation panel) as well as other devices to have control and a picture of their power consumption during the difficult months of winter 21-22, when the amounts from the bills were unimaginable. I learned about the consumption of various devices and fully understood the minimums. I had all the consumption data for the panel, recorded daily and for months, and that's how I learned how to handle the device to burn as needed, perform efficiently, and ultimately pay the minimum. Every kilowatt-hour is recorded, and you know what's happening. With the internet connection feature, I also had remote control of the devices. Truly, such devices must be owned by someone in their home. They teach you the proper use of devices and make your life easier. I highly recommend it.

I bought the socket for use with a coffee maker with a nominal consumption of 1000W. While the connection with wifi and the app was easy, every time I turn on the coffee maker, the socket turns off. It probably has some surge protection, but it is not the one advertised. It works fine with other devices (mobile charger)

If you want to monitor electricity consumption and not worry if you left any electrical device on when leaving the house, this socket will make your life easy.
Excellent construction, simple installation, and everything is okay...
I ordered another one and slowly I will probably put them in all the sockets.

I bought 1 piece and it is really excellent for its price! I would buy it again with closed eyes. Heavy, high-quality, and sturdy in construction

Amazing product. Full control via WiFi and easy connection with the app. CAUTION only during installation make sure to give permissions to the app for location etc so you don't have any issues. Afterwards, you can remove them. Opening and closing devices is very easy and you can accurately measure consumption as shown by the tests I did with devices whose consumption I knew. Essential product especially now with electricity prices so you don't have unpleasant surprises with your bill.

I would like a few more options in the app, it restricts you too much to only setting up lamps, coffee makers, and such small devices.
