The MyChevy component communicates with the
my.chevrolet website using selenium to log
in as your user, and screen scrape the data provided. GM does not
make it easy to sign up for any official development program, so this
provides a workaround to get access to your data.
This component provides the following platforms:
- Binary sensors - if the car is plugged in
- Sensors - such as Battery Level, Charge Mode, EST Range, Total Distance Traveled
To use MyChevy in your installation, add the following to your configuration.yaml file:
# Example configuration.yaml entry
mychevy:
username: email
password: password
{% configuration %} username: description: The email address associated with your my.chevrolet account required: true type: string password: description: The password for your given my.chevrolet account required: true type: string {% endconfiguration %}
{% linkable_title Installation %}
Because this uses selenium behind the scenes, installation is more complicated than merely pip install. See the installation instructions at https://github.com/sdague/mychevy.
{% linkable_title Limitations %}
The architecture of the GM automotive networking imposes some limitations on the functionality of the component.
The OnStar network link is very slow, and takes 1 - 3 minutes to get information back from the car. As such the mychevy component only polls every 30 minutes to not overwhelms that connection.
The OnStar network (or more specifically the gateway used by the my.chevrolet website) appears to suffer more than most networks when the car is a) in a garage, and b) it's cold outside (like < 15 degrees F). One of the provided sensors is a status sensor which indicates if we got connectivity with the car on the last polling cycle or not.
The "API" for this is written by web scraping. As such, it only currently is known to work if you have a Chevy Bolt EV, and only 1 Chevy car connected to OnStar. Patches for extended support should go to the https://github.com/sdague/mychevy project first, then Home Assistant can be extended.
