Enphase Envoy Battery reporting

Has anyone here got their Enphase AC Battery responding to commands from HA?

I’ve just posted about this topic and found a way to use the battery’s sleep mode as a workaround to prevent unwanted discharge - but I’d love to know if someone has already built something more elegant, or even contributed ACB support to an existing integration.

The key distinction: this is the older AC Battery unit, not the IQ Battery. They behave differently and need different API calls, which is why most existing Enphase integrations don’t help.

Would appreciate any pointers: Controlling Enphase AC Battery (ACB)
