You can check the consumption of your 230 Volt devices using a web browser. It's easy to build.
a web browser program displays the measured current and the power taken by the consumer
The Arduino Uno panel is connected to the home network using ethernet. From there, a web browser program displays the measured current and the power taken by the consumer. Of course, you can also buy ready-made smart gadgets that connect to the home wiki network and provide a lot of information about the consumption of a device. E.g.: 1P 63A eWelink single-phase Din Rail WIFI intelligent switch energy meter. You can find the Arduino code in the first post I wrote, a little below. That way, you don't have to download a file, copy the code, save it in a file called arammero.ino, and you can use it as shown in the video. arduino sketch 1.8.4 download: https://www.arduino.cc/en/software/Ol...
