Tesla Wall Connector Integration: Fix Unstable Connection

Hey everyone,

I'm writing about a persistent issue I've been experiencing with the Tesla Wall Connector integration in Home Assistant. Despite having a stable Wi-Fi connection, the integration frequently times out and becomes unavailable, only to immediately reconnect and reload. This has been an ongoing problem for quite some time, and it's becoming increasingly frustrating to manage.

The Ongoing Problem with Tesla Wall Connector Integration

Let's dive into the details of this issue. The primary concern is the unstable connection of the Tesla Wall Connector integration within Home Assistant. Even with a robust Wi-Fi setup, the integration consistently times out, leading to an unavailable status. This isn't a new problem; it's been recurring for years. However, the frequency of these timeouts has increased recently, making it more challenging to work around.

Understanding the Timeouts

The core of the issue seems to revolve around the integration's sensitivity to even minor network hiccups. While my Wi-Fi connection remains largely stable, the Tesla Wall Connector integration appears to be overly aggressive in timing out. To illustrate, consider this: out of 800 ping attempts, only 6 were lost. Yet, the integration timed out and went unavailable 6 times during this period. This suggests that the integration might be disconnecting prematurely, even when the Wall Connector itself remains connected to the network.

Visually, this looks like the following:

Previously, the integration would stay online for at least 2-3 hours before timing out. Now, it sometimes disconnects in less than 5 minutes, making it increasingly cumbersome to manage and integrate into my smart home automations.

Potential Causes and Contributing Factors

One potential cause is the Wi-Fi performance of Tesla devices. It's known that Tesla products sometimes have less-than-ideal Wi-Fi connectivity. Even with the Wall Connector placed in an optimal location, occasional packet loss is inevitable. This raises the question of whether the integration's timeout threshold is too low, causing it to disconnect unnecessarily.

To further investigate, I've been monitoring the Wall Connector's accessibility via its direct IP address. The http://[wall_connector_IP]/api/1/vitals endpoint seems to remain accessible even when the integration reports a disconnection in Home Assistant. This suggests that the Wall Connector itself is likely staying online, and the issue lies within the integration's handling of intermittent network disruptions.

This behavior is similar to issues reported by other users, such as #91285 and #105406, indicating a broader problem with the integration's stability.

Key Points:

• The Tesla Wall Connector integration frequently times out despite a stable Wi-Fi connection.
• The integration appears overly sensitive to minor network hiccups.
• The Wall Connector itself seems to remain online even when the integration disconnects.
• This issue has been ongoing for years, with the frequency of timeouts increasing recently.

Technical Details and System Configuration

To provide a clearer picture of the environment, here are some technical details and configuration specifics:

Home Assistant Core Version

I am currently running Home Assistant Core version core-2025.7.4. This is the version where I am experiencing the most recent issues with the Tesla Wall Connector integration.

Installation Type

My Home Assistant setup is running on Home Assistant OS. This is a dedicated operating system designed for Home Assistant, providing a streamlined and optimized environment.

Integration Details

The specific integration causing the issue is, of course, the tesla_wall_connector integration. This integration allows Home Assistant to communicate with and control the Tesla Wall Connector, providing valuable data and automation capabilities.

For more information about the integration, you can refer to the official documentation on the Home Assistant website:

Log Extracts and Error Messages

Reviewing the logs provides valuable insights into the nature of the problem. Here are some relevant log entries:

Logger: backoff
Source: components/tesla_wall_connector/__init__.py:50
First occurred: 4:45:00 PM (41 occurrences)
Last logged: 8:56:18 PM

Giving up async_request(...) after 3 tries (tesla_wall_connector.exceptions.WallConnectorConnectionTimeoutError: Timeout while connecting to Wall Connector at 192.168.10.30)
Giving up async_request(...) after 3 tries (tesla_wall_connector.exceptions.WallConnectorConnectionError: Error while communicating with Wall Connector at 192.168.10.30: Cannot connect to host 192.168.10.30:80 ssl:default [Connect call failed ('192.168.10.30', 80)])

These log entries indicate that the integration is experiencing connection timeouts and errors when attempting to communicate with the Wall Connector. The errors suggest that the integration is giving up after 3 retries, which might be too aggressive for environments with occasional network hiccups.

Configuration Snippets

Currently, there are no specific YAML snippets to share, as the issue seems to stem from the integration's core behavior rather than configuration problems.

Key Takeaways:

• Home Assistant Core version: core-2025.7.4
• Installation type: Home Assistant OS
• Integration: tesla_wall_connector
• Log entries indicate connection timeouts and errors.
• The integration retries only 3 times before giving up.

Proposed Solutions and Workarounds

Given the persistent nature of this issue, it's crucial to explore potential solutions and workarounds. Here are some ideas that might help mitigate the problem:

Increasing the Number of Retries

One potential solution is to increase the number of retries the integration attempts before considering the Wall Connector unavailable. As the logs indicate, the integration currently retries only 3 times. This might be insufficient for environments where occasional packet loss is expected. By increasing the number of retries, the integration might be able to tolerate minor network disruptions without disconnecting.

This adjustment could potentially be implemented within the integration's code or as a configurable option for users. A higher retry count would give the Wall Connector more opportunities to respond, reducing the likelihood of false disconnections.

Implementing a More Robust Connection Check

Another approach is to implement a more robust connection check. Currently, the integration might be relying on a simple ping or connection attempt, which can be susceptible to temporary network issues. A more sophisticated check could involve verifying the Wall Connector's status via its API endpoint (http://[wall_connector_IP]/api/1/vitals).

By periodically checking the API endpoint, the integration could confirm the Wall Connector's availability even if a ping fails. This would provide a more accurate representation of the device's status and prevent unnecessary disconnections.

Optimizing Wi-Fi Connectivity

While the issue seems to stem from the integration's behavior, optimizing Wi-Fi connectivity can still help. Ensuring a strong and stable Wi-Fi signal to the Wall Connector can reduce the frequency of network disruptions. This might involve repositioning the Wall Connector, upgrading Wi-Fi hardware, or adding a Wi-Fi extender.

However, it's important to note that even with optimal Wi-Fi conditions, occasional packet loss is still possible. Therefore, addressing the integration's sensitivity to these disruptions is crucial.

Community Collaboration and Solutions

Engaging with the Home Assistant community and Tesla Wall Connector users can provide valuable insights and potential solutions. Sharing experiences and troubleshooting tips can help identify common patterns and workarounds.

Key Suggestions:

• Increase the number of retries for connection attempts.
• Implement a more robust connection check using the Wall Connector's API.
• Optimize Wi-Fi connectivity to the Wall Connector.
• Engage with the Home Assistant community for collaborative solutions.

Conclusion and Call to Action

The Tesla Wall Connector integration issue of frequent timeouts and disconnections is a persistent challenge for many Home Assistant users. While the integration provides valuable functionality, its sensitivity to minor network hiccups can lead to a frustrating experience. By understanding the problem, exploring potential solutions, and engaging with the community, we can work towards a more stable and reliable integration.
