Run your go-e charging station from Home Assistant

Charge your electric car when the sun is out or when electricity is cheap, with a go-e charging station controlled from Home Assistant.

What it does

  • Charges the car with the surplus from your solar panels, without the go-e Controller box.
  • Pick a mode in one tap: off, charge now, solar surplus, automatic, dynamic tariff or static tariff.
  • Charges in off-peak hours, following a dynamic-tariff calendar or a static-tariff sensor, up to the battery level you aim for.
  • Sets the charge level to reach for the car’s battery.
  • Switches by itself between single-phase and three-phase charging, depending on the sun available.
  • Protects your installation: the power drawn from the grid is capped, to spare the circuit breaker.
  • Can stop the home battery from draining into the car.
  • An optional “Mobility” dashboard gathers the controls and settings.

How it works

  1. Turn on packagesOnce, add one line to Home Assistant’s configuration so it loads the files in the “packages” folder.
  2. Copy the fileDownload the package from GitHub into Home Assistant’s configuration folder.
  3. Adapt and restartReplace the serial number and address with those of your charger, check the configuration, then pick your mode in the interface.

Good to know

  • This is not an HACS integration. It is a configuration file (a “package”) that you copy into Home Assistant and then adapt, with your charger’s serial number and address. The guide on GitHub covers each step.
  • Tested on the Gemini model, with software 60.6. Other go-e models are not covered.
  • The guide’s examples use specific devices (a P1 meter, a SolarEdge inverter, a BYD car). Adapt the names, or remove the car automations if you do not have one.
  • The automatic tests check the logic, not the real charger. Check the result on your own charger after every change.
  • The guide on GitHub is written in French.
