Thanks for the explanation. This is all information that should have been in your first post. Having other equipment that limits current available to the EVSE would have been the first thing to check to make sure your EVSE was capable of putting out the max current in which case the Tesla could receive it. Also, showing a screenshot of the app while charging would have been a huge help to point you either towards the Tesla or to look elsewhere. Asking for help without disclosing all the relevant information and then not providing information requested to help solve your problem makes it seem like you want to blame Tesla but aren’t willing to accept any help.
Glad you got it figured out and it seems like you have an interesting power setup. Why would you limit the household current to 80% of the main breaker? Its not a continuous load so seems overkill to have that much safety margin.
