    It wants to read the current power as given by the photovoltaic with the ESP
    This code does not work. I get the answers
    !important;} .notice_content {j ; }} .web-hosting-90-off-image { ---Reading from solar---- server

    For web pages it is ok.
    Code: C / C++

    I connect to the LAN via WiFi
    The server on Sofar is working fine and the data is flowing out
    But trying to read from it to not install voltage measurement via ADC.

    Hi - I will also be trying to get this on the ESP soon. - The question is: did you manage to download the data?

    I have done the reading on the Raspberry OSMC
    The finished script will turn on the water heating when the power is above 2300w turns off at 1800w.
    You can also control from the server or from a file where I set the time to switch on, or switch the pins on.

    But I have a problem how to run the script automatically by OSMC during a power failure .

    Code: Bash

    .
    In normal Raspbian you add the starter to /etc/rcx.d,
    or to /etc/rc.local

    Thanks to FrankAB for the hints

    I have another problem with writing to the server with Bash
    curl "https://hkjhk.dgggfgdfgp.com/solar.php?moc=wrwrwrwerwerwer" #save to server and it's ok

    curl "https://hkjhk.dgggfgdfgp.com/solar.php?moc=$xxxx" #and here is the problem .

    I have a question on how to read in micropython .
    This function in the Arduino on the ESp32 reads data from the solar.

Topic summary

The discussion revolves around issues faced while attempting to read current power data from a photovoltaic system using an ESP microcontroller. The user reports that their HTTPClient code fails to retrieve the expected data from the server, which is operational. Subsequent responses inquire about the connection setup and whether data retrieval was successful. The user shares experiences with a Raspberry Pi setup for controlling water heating based on power readings and seeks advice on automating script execution during power failures. Additional queries involve reading data using MicroPython and issues with writing to a server using Bash scripts.
