Fixing Compass Card Tap_action Error In Version 3.0

Oct 13, 2025 by ADMIN 52 views

Hey guys! Today, we're diving deep into a common issue that many Home Assistant users have faced since the release of version 3.0 of the Compass Card: the dreaded tap_action error. If you've encountered the message "Compass Card: invalid yaml configuration. At path: tap_action.action -- Expected a string, but received: undefined," you're definitely in the right place. Let's break down this problem, understand why it happens, and, most importantly, learn how to fix it!

Understanding the `tap_action` Error

First off, let's get a clear picture of what this error message actually means. The error "Expected a string, but received: undefined" indicates that the Compass Card is expecting a text value (a string) for the tap_action.action configuration, but it's finding nothing (undefined). This typically arises because the configuration for the tap action is either missing or incorrectly formatted in your YAML file.

Diving into YAML Configuration: YAML (YAML Ain't Markup Language) is the human-readable data-serialization language used for configuration files in Home Assistant. It relies heavily on indentation and correct syntax. A small mistake, like a missing quote or incorrect indentation, can lead to errors that prevent your card from working correctly. In the context of the Compass Card, the tap_action setting defines what happens when you tap on the card in your Home Assistant interface. It could be navigating to another view, triggering a service, or more.

Why Version 3.0? You might be wondering, "Why did this start happening in version 3.0?" Updates to software often bring changes to the underlying code and how configurations are handled. In this case, version 3.0 likely introduced stricter validation of the tap_action configuration. This means that configurations that might have been silently ignored or defaulted in older versions now throw an error, making it essential to explicitly define the action you want to occur when the card is tapped.

Key Takeaway: The core of the issue lies in how the tap_action is defined (or not defined) in your Compass Card's YAML configuration. To resolve this, we need to ensure that the tap_action is correctly set up with a valid string value.

Diagnosing the Issue

Before we jump into solutions, let's make sure we accurately diagnose the problem. Here’s a step-by-step approach to help you pinpoint the exact cause of the tap_action error:

Step 1: Review Your YAML Configuration:

Locate the Compass Card Configuration: The first thing you need to do is find the YAML configuration for your Compass Card. This is usually located in your ui-lovelace.yaml file or within a specific view's configuration if you're using Lovelace UI in YAML mode. If you're using the UI editor, you’ll find the configuration by editing the dashboard and the specific card.
Examine the tap_action Section: Once you've found the Compass Card configuration, look for the tap_action section. This section is responsible for defining what happens when you tap on the card.

Step 2: Identify Common Configuration Errors:

Missing action Key: The most common cause of the "Expected a string, but received: undefined" error is a missing action key within the tap_action section. The action key specifies the type of action that should be performed, such as navigating, calling a service, or more.
Incorrect Indentation: YAML relies heavily on indentation. Ensure that the action key is correctly indented under tap_action. Incorrect indentation can lead to the configuration being misinterpreted.
Invalid action Value: The value assigned to the action key must be a valid string. Common valid actions include navigate, call-service, url, and more-info. If the action is misspelled or not recognized, it can cause an error.
Missing Quotes: In YAML, strings should be enclosed in quotes, especially if they contain special characters or spaces. Ensure that the value for the action key is enclosed in quotes if necessary.

Step 3: Check for Extraneous Settings:

Misplaced Settings: Sometimes, other settings might be misplaced within the tap_action section, causing conflicts. Make sure that only valid settings for tap_action are included in this section.

Step 4: Use the Developer Tools:

Check for Errors: Home Assistant’s developer tools can help you identify issues in your configuration. Go to the “Developer Tools” section in Home Assistant, and check the “Logs” tab for any error messages related to the Compass Card. These logs can provide more specific information about the error.

Example Scenario: Let’s say you have the following configuration:

type: custom:compass-card
tap_action:
  entity: sensor.wind_speed

In this case, the action key is missing, which will cause the "Expected a string, but received: undefined" error. The correct configuration should include the action key:

type: custom:compass-card
tap_action:
  action: more-info
  entity: sensor.wind_speed

By systematically reviewing your YAML configuration and checking for these common errors, you can effectively diagnose the tap_action issue in your Compass Card.

Implementing the Fix

Alright, let's get our hands dirty and fix this tap_action error! We've diagnosed the problem, so now it's time to implement the solution. Here’s a step-by-step guide to help you correct your Compass Card configuration:

Step 1: Access Your Configuration File:

Navigate to Your Configuration: Depending on how you have your Home Assistant set up, you’ll need to access your configuration files. If you're using the UI editor, you can edit the dashboard directly. If you're using YAML mode, you'll need to access your ui-lovelace.yaml file or the relevant YAML file where your Compass Card is configured. You can use the Home Assistant File Editor add-on, Samba share, or any other method you prefer to access these files.

Step 2: Correct the tap_action Configuration:

Add the action Key: The most common fix is to add the action key to your tap_action section. The action key specifies what should happen when you tap on the Compass Card. Here are some common actions you can use:
- more-info: Opens the more-info dialog for the specified entity.
- navigate: Navigates to a different view in your Lovelace UI.
- call-service: Calls a Home Assistant service.
- url: Opens a specified URL in a new tab.
Example Configuration: Let's say you want to open the more-info dialog for a sensor when you tap the Compass Card. Here’s how you would configure it:
```
type: custom:compass-card
# other configurations...
tap_action:
  action: more-info
  entity: your_sensor_entity_id
```
Replace your_sensor_entity_id with the actual entity ID of your sensor.
Using navigate Action: If you want to navigate to another view in your Lovelace UI, use the navigate action. You’ll need to specify the navigation_path to the view.
```
type: custom:compass-card
# other configurations...
tap_action:
  action: navigate
  navigation_path: your_view_path
```
Replace your_view_path with the path to the view you want to navigate to.
Using call-service Action: If you want to call a Home Assistant service, use the call-service action. You’ll need to specify the service and service_data.
```
type: custom:compass-card
# other configurations...
tap_action:
  action: call-service
  service: your_service
  service_data:
    entity_id: your_entity_id
```
Replace your_service with the service you want to call and your_entity_id with the entity ID if required by the service.

Step 3: Ensure Correct Indentation:

YAML Indentation: YAML is very sensitive to indentation. Make sure that your action key and its associated values are correctly indented under the tap_action section. Incorrect indentation can lead to parsing errors.
Correct Example:

type: custom:compass-card tap_action: action: more-info # Correct indentation entity: sensor.wind_speed # Correct indentation


**Step 4: Save Your Configuration and Restart Home Assistant:**

*   **Save Changes:** After making the necessary changes, save your configuration file.
*   **Restart Home Assistant:** To ensure that the changes are applied, restart your Home Assistant instance. You can do this from the Home Assistant UI by going to “Configuration” -> “General” and clicking on “Restart.”

**Step 5: Clear Cache and Test:**

*   **Clear Browser Cache:** Sometimes, your browser might be holding on to cached versions of the UI, which can prevent the changes from showing up. Clear your browser’s cache to ensure you're seeing the latest version.
*   **Test the Tap Action:** Finally, test the Compass Card by tapping on it. It should now perform the action you’ve configured, such as opening the more-info dialog or navigating to another view.

By following these steps, you can effectively fix the `tap_action` error and get your Compass Card working as expected. If you’re still encountering issues, double-check your YAML configuration for any typos or indentation errors.
