EV Charger Card

EV Charger card for Home Assistant Lovelace UI

OBS! This readme reflects the latest release candidate for testing which brings a lot of breaking changes since the card is made generic. See here for an older version which is currently the latest official release.

By default, Home Assistant does not provide any card for controlling chargers for electrical vehicles (EVs). This card displays the state and allows to control your charger - and it is now made fully customizable so you could also use it for «anything» else as well, for instance your electric car.

💡 Tip: If you like this project consider buying me a cup of ☕️:

Installation

Installation with HACS

Installation with HACS (Home Assistant Community Store) is highly reccomended but requires that you have this installed on your Home Assistant. The charger-card is available just by searching for Charger Card under the Frontend-section of HACS.

Manual

1. Download charger-card.js file from the latest-release.
2. Put charger-card.js file into your config/www folder.
3. Add reference to charger-card.js in Lovelace. There are two ways to do that:
   1. Using UI: Configuration → Lovelace Dashboards → Resources → Click Plus button → Set Url as /local/charger-card.js → Set Resource type as JavaScript Module.
   2. Using YAML: Add following code to lovelace section.

      resources:
        - url: /local/charger-card.js
          type: module

4. Add custom:charger-card to Lovelace UI as any other card (using either UI-editor or YAML-configuration).

Configuring and using the card

After installation, the card can be configured either using Lovelace UI editor or YAML-code.

1. In Lovelace UI, click 3 dots in top left corner.
2. Click Configure UI.
3. Click Plus button to add a new card.
4. Find Custom: Charger Card in the list.
5. Choose brand from the list which fits your need or select other.
6. Choose entity and select the main status sensor of your charger.
7. Now you should see the preview of the card!
8. Do your customizations in UI editor or manually in the YAML code editor.

A minimum example of using this card in YAML config would look like this:

type: 'custom:charger-card'
brand: easee
entity: sensor.easee_status

Here is a list of the basic options. See advanced configuration further down for more details.

Name	Type	Default	Description
type	string	Required	custom:charger-card
brand	string	Required	Select the template charger or system. If available it will try to set a pre-defined setup for your system and will assume you have all entities with default names from the integration. You can still edit your configuration in YAML if you system does not comply with these assumptions. See advanced config for further details.
entity	string	Required	The main status sensor for your charger (for Easee, look for the one named status).
customCardTheme	string	Optional	Select a built-in theme of colors, or use theme_custom to apply the theme you have applied in HA.
chargerImage	string	Anthracite	Select a charger image from the built-in default images
customImage	string	Optional	Path to custom image of your charger (png or svg). This will override the chargerImage selection. (For images in the www-folder of HA, try path \local\image.png
compact_view	boolean	false	Show a compact view of the card.
show_name	boolean	true	Show a friendly name of the charger and the location (if provided)
show_leds	boolean	true	Show status leds for the charger, fits best with Easee chargers and when using built-in images.
show_status	boolean	true	Show status of the charger.
show_collapsibles	boolean	true	Show the collapsible menu buttons which will open detailed sensors when clicked.
show_toolbar	boolean	true	Show a toolbar with buttons that can call a service or do stuff.
show_stats	boolean	true	Show data table (stats).
details	details	Optional	Details for customization if the default brand template doesn't do what you want it to. This mus be done manually with YAML-code. See advanced configuration

Features

• Fully customizable for your needs, the card works for different chargers and other entities if you read the advanced configuration section and customize it to your needs. For chargers that are supported by default templates, the setup is very easy: select brand and main entity and you should be done.
• Animations: If choosing the default images of Easee chargers in any color, you can also choose to show leds which will behave according to charger status. This is identical to how the charger looks physically and similar to the Easee app and web site. Two leds for standby, all leds when connected, flashing while charging and so on. If SmartCharging is enabled, leds will be blue.
• Collapsible menu buttons: Click on one of the menu buttons (if you have enabled them) to get more info, config or limit settings. Can also be customized.
• Possibility to set current limits from UI. Current limits can also be customized.
• Customizable data table (stats) items that can depend on charger status and show relevant information.
• Customizable toolbar with buttons to call services or do something which. The toolbar can depend on charger status and show relevant actions.

Supported languages

This card supports translations. Please, help to add more translations and improve existing ones. Here's a list of supported languages:

• English
• Norsk bokmål (Norwegian)
• Svenska (by jockesoft)
• German (by DeerMaximum)
• Danish (by dykandDK)
• Catalan (by gerardag)
• Your language?

Supported models

This card was originally made to support charging robots from Easee, but has been further developed to be fully configurable and customizable and can be used with any kind of charger. It can even be used for other things than EV-chargers, for instance your electric car or something completely different. Some brands are added with built-in support to make the configuration really easy:

• Easee
• Your charger?

Advanced configuration

If your brand is on the list of supported models, you should be able to get away just by selecting the brand and entity main sensor from the UI editor of Home Assistant. However, if you want to fully customize it or use it for something else than supported by default brands, you must do this yourself with YAML-code. It may seem overwhelming at first, so a trick can be applying a built-in brand as a template and start modifying the YAML code from there - this will give you the basic structure. Also see the examples further down.

Name	Type	Default	Description
debug	boolean	false	Apply true to enable some debugging features which will appear in Developer Tools of your browser (Ctrl+Shift+I in Chrome). Useful if something doesn't work.
localize	boolean	true	Apply false to disable all translations, for instance if you want to fully customize texts and the translation feature for some reason messes up you stuff. Normally not necessary.
details	details		Details for customization if the default brand template doesn't do what you want it to. See details-items

Details items

Config	Text
name	Single entity with configuration details as shown in entity-items.
location	Single entity with configuration details as shown in entity-items.
status	Single entity with configuration details as shown in entity-items.
substatus	Single entity with configuration details as shown in entity-items.
smartcharging	Single entity with configuration details as shown in entity-items. Controls white or blue leds for easee chargers.
info_left	List of entities with configuration details as shown in entity-items. Defines static icons shown top-left of the card.
info_right	Same as info_left, but for static icons shown top-right of the card.
group1	List of entities with configuration details as shown in entity-items. Defines the content of first collapsible-button (default: limits).

stats	Provide the states of entity defined as main status sensor, then a list of entities with configuration details as shown in entity-items. Defines the datatable statistics (stats) in lower part of card. It may change depending on status of charger, or it is possible to define default as a state. See example.
toolbar_left	Provide the states of entity defined as main status sensor, then a list of entities with configuration details as shown in entity-items. Defines the left aligned command buttons on the toolbar at the bottom of the card. It may change depending on status of charger, or it is possible to define default as a state. See example.
toolbar_right	Same as toolbar_left but right aligned command buttons on the toolbar.
currentlimits	Override the card default current limits by specifying a list of numbers. Used for current limit features of the card (if configured).
statetext	Override or custom-translate the status sensor state by providing better or cleaner text. See example.
collapsiblebuttons	Specify text and/or icon to customize the collapsible-buttons group1,group2 and group3 respectively. See example.

Entity items

Config	Text
entity_id	Specify an entity id that you want to use for the specific feature. Enter calculated to perform mathematical functions instead, see further down how.
attribute	You can specify an attribute of the entity to use instead of entity state as value.
unit	Card will use the entity unit_of_measurement as default, but you can override it here by entering the unit you want.
unit_show	Define if the unit should be shown next to the value or not.
unit_showontext	Define if the value and unit should be shown next to the tooltip text
text	Card will use the entity friendly_name as default, but you can override it here by entering the text you want. Used as tooltip text for icons and as information on stats.
service	You can specify a service that you wish to link to the entity, check available services in HA Developer Tools. Use full format like domain.servicename
service_data	Specify the service data corresponding to the service you want to call. If it is not a static call, but for instance a call with a value selected from a dropdown menu, enter #SERVICEVAL# as a special token which will be replaced by the card when called. See advanced configuration for example.
icon	Card will use the entity icon as default, and will try to detect device class icons as well. If you want to override it, do it here by specifying a valid icon.
round	If you would like to round down the number, specify an integer to define the number of digits.
type	Choose between info, service and dropdown. Info-items will appear as icons with tooltip, clicking them opens the more-info popup for the entity. Service-items will do the same, but call a service when clicked (if it is provided). Dropdown-items will show a dropdown list to select from a list and call a specified service with this number as service data.
calc_function	Choose between min, max, mean, sum to define a mathematical function to be performed on a specified list of entities or attributes. The result will be used on the sensor provided you specify calculated instead of a real entity_id. Then add a list of entities to be calculated in calc_entities.
calc_entities	A list of entites or entity attributes that are used for the mathematical function. Specify a list of entity_ids and add attributes if you prefer to use that.
conditional_entity	Specify a boolean entity (returning on/off or true/false) to define if the entity should be shown based on state condition.
conditional_attribute	Specify a boolean entity and its attribute (returning on/off or true/false) to define if the entity should be shown based on state attribute condition.
conditional_invert	Invert the conditional rule, so that true/on means hide and false/off means show
