If your Go-e Gemini wallbox is installed outdoors, you likely protect it against unauthorized access using RFID authorization or app confirmation. The everyday problem: with authorization lock active, Home Assistant cannot simply start charging via standard commands like “Force State”. By using a HACS integration via MQTT, you can toggle the card lock as an entity and control charging directly.
What you need
- Home Assistant
- Go-e Gemini wallbox
- MQTT integration in Home Assistant
- HACS
1. Install the HACS repository
Install the custom integration repository syssi/homeassistant-goecharger-mqtt via HACS to gain access to advanced switches and configuration parameters for your wallbox.
2. Restart Home Assistant
Restart Home Assistant under Settings > System so that the system loads the newly added integration files.
3. Verify the MQTT connection
Make sure your Go-e wallbox is connected via MQTT and is actively transmitting data to Home Assistant.
4. Locate the authorization switch
Look for the card authorization required switch for your Go-e wallbox. This switch is provided by the HACS integration to configure the charging station’s authorization settings and enable charging without the app.
5. Control charging via the switch
Unlocking and starting the charge is handled through this switch: As soon as your vehicle is plugged in, set card authorization required to off to enable charging. Switching it back to on secures the station against unauthorized use again.
Does it work?
Plug the charging cable into your vehicle. In Home Assistant, turn off the card authorization required switch on your wallbox. The Go-e Gemini will initiate charging without requiring you to tap the blue authorization button in the Go-e app.
Troubleshooting
- Charging does not start despite Force State “On”: When the wallbox is awaiting authorization, it ignores standard charge commands. You must disable the card lock via
card authorization required. - Entity not found: Standard MQTT auto-discovery does not create this switch. Check whether the HACS integration
syssi/homeassistant-goecharger-mqttis properly installed and loaded. - No connection over MQTT: Check the connection settings in your MQTT configuration.
- Entity remains unavailable: Restart Home Assistant and verify that the MQTT integration is active.
