Volkswagen We Connect - An Home Assistant custom component to interact with the We Connect service

Description

Welcome to Volkswagen We Connect custom component designed for Home Assistant with the capability to interact with the Volkswagen We Connect service (your car).

This custom component supports the "non-ID" Volkswagen We Connect cars such as the Passat, Golf, e-Golf, Tiguan etc. It requires you to have an active and working VW online subscription connected to your car. For the new electric vehicles such as the ID series this component does not work. The new ID platform uses another backend system.

Most of the functionality found the "We Connect app" should be available via this integration, this includes options such as auxiliary heater control.

Note: Some features included in Volkswagen We Connect 2019 and newer are not fully tested. This custom component should work with any models such as Golf/Passat 8.5/Tiguan etc. But please bear with me and report any fault or error as an issue.

Please note that there has only been reports of success with this component for cars sold (and based) in the EU. Please feel free to contribue to make this component work in the US as well, we do not have access to any We Connect accounts to verify at this stage.

Having issues with this custom component?

Please, before posting an issue make sure that VW´s WeConnect service works for you via a normal web browser. Not only the login part but also make sure that the VW WeConnect service interacts with the car proper, including updating of all sensors and location. If there are problems with the VW WeConnect service this component will not work either. This custom component is only as good as the VW WeConnect service.

Installation

Upgrading from an old component version

Remove all configuration from Home Assistants config file configuration.yaml
Upgrade the component via HACS or manually replace the files in the custom_component folder (see install manually below)
Restart Home Assistant
Add the component again as per below (install+configuration)

Install with HACS (recommended)

Do you you have HACS installed? Just search for Volkswagen We Connect and install it direct from HACS. HACS will keep track of updates and you can easly upgrade this component to latest version.

Install manually

Make sure you have an account on Volkswagen We Connect.

Clone or copy the repository and copy the folder 'homeassistant-volkswagencarnet/custom_component/volkswagencarnet' into '/custom_components'

Installing dependencies

Note that only the packaged releases (zip file) have the dependencies configured so that Home Assistant can find them automatically, but if you use the source code or git branch, you need to manually install the correct versions of all dependencies also using something like pip install -r requirements.txt.

Configuration

Restart Home Assistant
Add and configure the component via the UI: Configuration > Integrations > search for "Volkswagen We Connect" and follow the wizard to configure (use your We Connect credentials)
All available features of your car should be added automatically after you have selected the VIN

Configuration flow settings

Name your car - Enter a custom name, defaults to VIN (Optional)
Username/Password - We Connect (Required)
Region - The country where the car was sold (Required)
Mutable - If enabled you can interact with the car, if disabled only data from the car will be presented (Optional)
S-PIN - Required for some specific options such as lock/unlock (Optional)
Distance unit conversion - Select if you wish to use "Swedish mil" or Imperial Miles instead of KM (Optional, default is KM)

Entities

This plugin creates entities in the format DOMAIN.NAME_ENTITY. Not all entities are created for all make, year and models, for example pure electric cars will not have entities only applicable to cars with a combustion engine.

Automations

In this example we are sending notifications to an ios device

Save these automations in your automations file <config dir>/automations.yaml

Custom sensors

Total electric consumption

This integration may only report the electrical engine consumption, recuperation and auxillary consumer consumption, but no combined total. This example template sensor implements the missing sensor. Add to configuration.yaml and replace [ID] by your car's name.

sensor:
  - platform: template
    sensors:
      [ID]_last_trip_total_electric_consumption:
        value_template: >-
          {{ (   states('sensor.[ID]_last_trip_average_electric_engine_consumption') | float
               + states('sensor.[ID]_last_trip_average_auxillary_consumer_consumption') | float
               - states('sensor.[ID]_last_trip_average_recuperation') | float
             ) | round(1) }}
        unit_of_measurement: 'kWh/100km'
        friendly_name: '[ID] Last trip total electric consumption'

Templates for converting distance from km to miles

As of v4.4.45 the same can be acheived by setting the distance units to Imperial in the integration configuration page.

These templates create a new sensor with kilometers converted to miles. Add to your configuration.yaml and replace [ID] with your car's name. Note: these are for a BEV, other models may have different sensor names.

  - platform: template
    sensors:
      [ID]_service_inspection_distance_miles:
        friendly_name: '[ID] Service inspection distance miles'
        value_template: "{{ (states('sensor.[ID]_service_inspection_distance').split(' ')[0] |int * 0.6213712) | round(0)}}"
        unique_id: [ID]inspectionmiles
        unit_of_measurement: mi
        icon_template: mdi:garage
      [ID]_combined_range_miles:

        value_template: "{{ (states('sensor.[ID]_combined_range').split(' ')[0] |int * 0.6213712) | round(0)}}"
        unique_id: [ID]rangemiles

        value_template: "{{ (states('sensor.[ID]_odometer').split(' ')[0] |int * 0.6213712) | round(0)}}"
        unique_id: [ID]odometermiles

        value_template: "{{ (states('sensor.[ID]_last_trip_average_speed').split(' ')[0] |int * 0.6213712) | round(0)}}"
        unique_id: [ID]ltaspeedmi
        unit_of_measurement: mi/h
        icon_template: mdi:speedometer
      [ID]_last_trip_length_miles:
        friendly_name: '[ID] Last trip length miles'
        value_template: "{{ (states('sensor.[ID]_last_trip_length').split(' ')[0] |int * 0.6213712) | round(0)}}"
        unique_id: johnny5lasttriplengthmiles
        unit_of_measurement: mi
