I have problem setting up your integration - I have correct local IP adress of my Solax EV Charger (X3, not sure about generation, probably G1), i checked password (can log into local web page of Solax EV Charger), but after setting up integration I got error:

This error originated from a custom integration.

have no clue, what is the problem :-)

I looked to code and there is possibility that some special character is not permited in password.

@mpasecny please test foloowing:'

1. temporary change password to something really simple. Test if integration can be setup.
2. If it is problem with password, let me know which special characters ware possible problem.

I'll test and find a fix. Thanks.

[mpasecny]

so in the end, problem was, that password was TOO LONG, maximum appears to be 10 characters, but Solax accepts far more characters, so I do not know, if problem is on HA, or somewhere in between...

[PatrikTrestik]

Thanks for finding out.
I'll check if there is limit on HA side.
If not I can add check and configuration error to describe it.

[PatrikTrestik]

I confirmed that API alows only 10chars due to SolaX limitation.
It might be bug on their side, but for now I added 10 max chars requirement.

Will be in next release 1.3.5
