This project is now archived due to MyChevy being removed from Home Assistant. Chevrolet has made it almost impossible for it to work due to constant authentication changes

Home Assistant My Gas Chevrolet

This is a modification of the My Chevrolet Integration from Home Assistant. While I do not has an electric vehicle (EV), I do have a gas Chrevolet that uses the My Chevrolet app. With a little bit of fiddling, it is possible to retrieve the gas-related inforation, so I can track my fuel economy, and how much gas I have left. Eventually I would like to figure out how to retrieve other information such as oil life and tire pressures.

Installation

Manual

Copy the mygaschevy folder to the custom_components folder in your Home Assistant configuration directory:

/home/homeassistant/
├── .homeassistant
│   ├── custom_components
│   │   └── mygaschevy

HACS

Under Custom Repositories, add https://github.com/dennyreiter/hass-mygaschevy as an integration. Then install.

Configuration

Add the following code in your configuration.yaml file:

mygaschevy:
    username: YOUR_USERNAME
    password: YOUR_PASSWORD

Configuration

key	required	type	usage
username	true	string	The email address for the MyChevrolet account
password	true	string	The password for the MyChevrolet account

Just like the My Chevrolet integration, it can take two to three minutes for the results to be returned.

The created sensors will be in the form of sensor.mygaschevy_VEHICLE_NAME.*

sensor	description
sensor.mygaschevy_VEHICLE_NAME_fuel_economy	miles per gallon per vehicle
sensor.mygaschevy_VEHICLE_NAME_fuel_percentage	percentage of fuel left in the tank
sensor.mygaschevy_VEHICLE_NAME_gas_range	approximate range in miles per vehicle
sensor.mygaschevy_VEHICLE_NAME_mileage	the vehicle mileage

Example Binary Sensor

binary_sensor:

  - platform: template
    sensors:
      truck_gas_low:
        friendly_name: "Truck Gas Level Low"
        device_class: gas
        value_template: >-
          {{ states('sensor.mygaschevy_2011_chevrolet_silverado_1500_fuel_percentage') | int < 18 }}
