The charger and installation "active" binary sensors dumped the full Zaptec object state as extra_state_attributes, refreshed on every poll. Because that attribute set changes on nearly every poll and can exceed Home Assistant's 16 KB limit, it caused recorder "State attributes ... exceed maximum size" warnings (custom-components#382) and is the leading suspect for the companion-app black screen (custom-components#386). Almost all of these values are already exposed as dedicated entities, and the attributes have seen no real troubleshooting use (custom-components#297). Also surface the charger's Zaptec device id as the device serial number in the device registry, matching what the Zaptec app shows. This is an additive, non-breaking change. BREAKING CHANGE: The active charger and installation binary sensors no longer expose the Zaptec object fields as state attributes. Automations, templates or dashboards that read those attributes must use the dedicated entities instead. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
