Unfortunately what you are asking is a paradox.
OpenEVSE is an open platform with a open protocol and no network which supports advanced features and integrations.
Basic requirements of the program are network operated and UL/Energy Star certified, this is exactly the opposite of open. This requires closed protocols on a proprietary network with a locked down configuration. Control and integrations with HASS on a UL certified EVSE is probably not possible. Most control and integration features would have to be removed to achieve NRTL certification.

Hello,
I just purchased my first EV and obvious next thing I am shopping for Level 2 home charger. As an avid HASS user, the search for HASS-compatible EV chargers led me to this company which seemed like absolutely ideal charger for me with its open software firmware, no required cloud account nor required apps etc.. Looks like a very well-built unit too. What's not to love? Well, one teeny-tiny detail: My home state of NJ has a program that gives money back up to $1500 (customer-side installation and materials, including charger itself. The catch is you must use one of the qualified chargers and OpenEVSE is unfortunately not yet on that list. It pains be to have to purchase a known big-brand alternative EV charge, but missing $ 1500 would be hard.
Please see if you could get on that list. I don't have details of the necessary changes, but I imagine something like sending charging logs to the electrical company.
