Support for Omnik 3000TL

[dvherk]

Can support for Omnik 3000TL be added?
The screenshot in de README looks 100% as this inverter.
It logs by default to SolarMan Smart App/portal.
My inverter exposes an open port 8899.
I have the wifi only version.

I am able to get data via tcp client via this 'data logger': https://github.com/gcmvanloon/omnik-data-logger/

In that is a file OmnikExport.py that shows this, which is I guess how the dat export is build up->

def generate_string(serial_no):
"""Create request string for inverter.

    The request string is build from several parts. The first part is a
    fixed 4 char string; the second part is the reversed hex notation of
    the s/n twice; then again a fixed string of two chars; a checksum of
    the double s/n with an offset; and finally a fixed ending char.

    Args:
        serial_no (int): Serial number of the inverter

    Returns:
        str: Information request string for inverter
    """
    response = '\x68\x02\x40\x30'

    double_hex = hex(serial_no)[2:] * 2
    hex_list = [double_hex[i:i + 2].decode('hex') for i in
                reversed(range(0, len(double_hex), 2))]

    cs_count = 115 + sum([ord(c) for c in hex_list])
    checksum = hex(cs_count)[-2:].decode('hex')
    response += ''.join(hex_list) + '\x01\x00' + checksum + '\x16'
    return response
