go-e Charger Gemini Flex 2.0 (22 kW) - A local HTTP API and WebSocket push let Home Assistant control the charger on the LAN

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, and MQTT, Modbus TCP and OCPP 1.6 are all available locally too. Just note: this is a European product only - it takes a three-phase 400V CEE red supply and a Type 2 socket, so there is no North American SKU and it will not run on US split-phase 240V service.

Buying reality check

Price notes: Roughly EUR 585-650 for the 22kW model across EU retailers (geizhals price comparison, checked 2026-08-19). Sold in Europe only. A premium pick. The US Amazon listing read Currently unavailable on 2026-09-06 at a $634.10 last-seen price, a grey-import figure rather than a real US channel, so the buy button points at go-e direct.
