Home Assistant integration for the go-eCharger (WIP)

Integration for Homeassistant to view and Control the go-eCharger for electric Vehicles via the local ip-interface via API Version 1. In newer chargers the V1 API has to be enabled via the App first.

Features

• attributes from charger available as sensors
• switch to turn off/on charger
• set charge limit in kWh (0.1 kWh steps)
• set max current for charging in ampere (6-32A)
• set absolute maximum current for charging (max can not be set higher than "absolute max")
• no cloud connection needed to control the charger - only local ip-access needed.
• correction factor for older devices which often present 5-10% lower voltage and therefore energy values

Warning: WIP - Breaking changes possible

This is the first version of the Integration so there are still breaking changes possible.

Installation

• clone this repository

git clone https://github.com/cathiele/homeassistant-goecharger.git

• copy the content of the custom_components-Folder to the custom_components folder of your home-assistant installation

# mkdir -p <your-ha-config-dir>/custom_components
# cp -r custom_components/goecharger <your-ha-config-dir>/custom_components

• setup your Charger in the configuration.yaml (for always connected chargers):

goecharger:
  chargers:
    - name: charger1
      host: <ip of your charger>
    - name: charger2
      host: <ip or hostname of charger 2>
      correction_factor: factor for correction for total and session charged
