Does Hoymiles HM / HMS / HMT microinverters work locally with Home Assistant?

Yes, according to the public sources: the HACS integration “Hoymiles SolarPV” talks to it over the local network, read-only as far as we can tell; evcc supports it locally for metering.

Firmware updates can open or close local access — check the integration's own page before you buy, and your installer before software changes export limits or charges a battery from the grid.
