CarConnectivity-Addon Configuration Guide

Introduction

The CarConnectivity-Addon module allows you to connect and retrieve information about your vehicle from compatible manufacturers' online services. This guide explains how to properly configure the module. I am simply packaging the excellent work done by Till.

General Configuration

Only fill in the settings for the brands of vehicles you own. Leave all other fields empty.

1. Selecting Your Vehicle Brand

Choose the manufacturer corresponding to your vehicle from the supported brands:

• Seat/Cupra
• Skoda
• Volkswagen
• Tronity

If you own multiple vehicles from different brands, you can configure multiple sections.

2. Connecting to the Manufacturer’s Online Services

Each car manufacturer provides an online service that allows you to access your vehicle's data remotely. To connect, you need to provide your login credentials.

Required Information:

• Username: The email address used to log into the manufacturer’s service.
• Password: The password for your manufacturer account.
• PIN Code: A 4-digit code required for remote access to certain vehicle features.
• Refresh Interval: Defines how often (in seconds) the vehicle's data is updated.
  • Warning: Setting a refresh rate too frequently may exceed the API request limits imposed by the manufacturer, resulting in temporary access restrictions.

⚠️ Special Case: Seat/Cupra Connector

The Seat/Cupra connector includes an additional option:

• Manufacturer Brand: Allows you to use brand-specific features.
  • Select the corresponding brand (Seat or Cupra) to ensure proper data retrieval.

3. MQTT Configuration (Mandatory)

You need to use MQTT to send vehicle data to home assistant, configure these settings:

• Username: MQTT broker login
• Password: MQTT broker password
• Broker Address: IP or domain name of the MQTT server

⚠️ If you're not already using MQTT on Home assistant, you can add, for example, Mosquito addon AND MQTT integration

4. Logging Level

Define the amount of information recorded in logs:

• Info: Displays general operational information.
• Warning: Displays only warnings.
• Error: Displays only error messages.
• Debug: Displays additional details useful for troubleshooting.

Best Practices

• Only fill in the settings for the vehicle brands you own.
• Do not share your login credentials.
• Adjust the refresh interval to avoid exceeding API request limits. Remember limit seems to be about 1000 req/day
• Use the "Debug" logging level only when troubleshooting issues.
