Hi, you understand me correctly. And no, at this moment I cannot extract the values from the Bluetti, that’s the whole problem at the moment. I cannot establish a good connection between the ESP32 and the Bluetti. If I can make that work, the flows will not be the problem 
EDIT: I started with this topic [HOW TO] Advanced Virtual Device for Bluetti devices (need an ESP32) - #6 by Peter_Kawa and with the use of AI I managed to get this code working to write it to the ESP32 board. However, no data was extracting from the Bluetti (or no connection was made). AI rewrote a lot of the code but at the end I even couldn’t write the code to the ESP32. According to AI the code was too old for the Bluetti. I did manage to extract some data from the Bluetti with another code, but that data was not useful, at least not at the moment. I got 10 packages of data, there where 5 packages stable, and 5 packages have values which where very fluctuating every second. So what I need first (if this is possible), is a good working code to flash into the ESP32. Or maybe there’s a complete other way to extract the data from the Bluetti AC180P
