go-e Charger Gemini Flex 2.0 (22 kW)

Quick verdict

A documented local HTTP API v2 plus WebSocket push lets Home Assistant read and command the charger entirely on the LAN with no cloud account. The go-e local HTTP API v2 and WebSocket interface are exposed on the LAN and the HA integration talks to them directly, bypassing go-e's cloud. Just note: Type 2 (European) connector - US buyers need an adapter.
