Quick verdict

Fully open-source hardware and firmware with a local-push Home Assistant integration plus native MQTT, so the charger never needs the internet. Open firmware speaks MQTT/HTTP directly on your LAN and the HA integration is Local Push with no vendor cloud in the path. Just note: Premium price and largely DIY/kit ethos.
