Understanding the Problem: Target Temperature Troubles

The core of the issue lies in the target_temp functionality within the Daikin AC integration. After updating Home Assistant, users have found that they can no longer adjust the target temperature of their Daikin air conditioners through the Home Assistant interface. This means you might be stuck with a fixed temperature, unable to cool down or heat your home to your preferred setting. This can be incredibly frustrating, especially during extreme weather conditions. Understanding the root cause is crucial, and often it boils down to integration updates, configuration errors, or communication glitches between Home Assistant and your Daikin AC unit. Let’s explore the potential culprits and how to address them to regain control over your home climate.

Why is Target Temperature Control Important?

Having precise control over your AC's target temperature is essential for maintaining a comfortable and energy-efficient home environment. Setting the right temperature not only ensures your comfort but also prevents your AC from overworking, saving you money on your energy bills. Without this control, your system might run excessively, leading to higher costs and potential wear and tear on your equipment. Moreover, integrating this functionality into your smart home ecosystem allows for automated temperature adjustments, creating personalized comfort profiles, and optimizing energy usage based on factors like time of day or occupancy. Regaining control over the target temperature means returning to a more comfortable, efficient, and personalized home climate experience.

Potential Causes and Solutions

Let's investigate the common reasons behind the target temperature malfunction and explore corresponding solutions:

1. Integration Update Issues

Often, updates to Home Assistant or the DAIKIN AC integration itself can introduce bugs or compatibility issues. The reported version 2025.11.3 might contain specific issues related to target temperature control. While the version number seems to be a typo (likely referring to a version in 2023 or 2024), the principle remains the same: new updates can sometimes disrupt existing functionality. To address this:

  • Check for Updates: First, ensure you are running the latest version of the DAIKIN AC integration. Go to HACS (Home Assistant Community Store) if you installed the integration through it, or check the official Home Assistant integrations page. Updates often include bug fixes that address these types of issues.
  • Review Release Notes: Always read the release notes for both Home Assistant and the DAIKIN AC integration. These notes often highlight known issues and workarounds. You might find a specific mention of the target temperature problem and a recommended solution.
  • Downgrade (Temporarily): If the issue arose immediately after an update, consider temporarily downgrading to the previous version of the integration. This can help you regain control while waiting for a permanent fix. However, be aware that downgrading might introduce other issues or security vulnerabilities, so it's a temporary solution.

2. Configuration Errors

Incorrect configuration settings can also prevent the target temperature from working correctly. This could be due to typos in your configuration files, outdated settings, or conflicts with other integrations. To troubleshoot configuration errors:

  • Review Configuration: Carefully examine your configuration.yaml file (or any other relevant configuration files) for the DAIKIN AC integration. Look for any errors, typos, or incorrect values. Ensure that the entities for your Daikin AC are correctly defined and that the target_temperature entity is present.
  • Check Entity IDs: Verify that the entity IDs for your Daikin AC are correct. You can find these IDs in the Home Assistant Entities panel. If the IDs are incorrect, the integration won't be able to communicate with your AC properly.
  • Consult Documentation: Refer to the official DAIKIN AC integration documentation on the Home Assistant website (https://www.home-assistant.io/integrations/daikin/). The documentation provides detailed information on configuring the integration and troubleshooting common issues. Make sure your configuration aligns with the documented requirements.

3. Network and Communication Issues

The DAIKIN AC integration relies on communication between Home Assistant and your Daikin AC unit, typically over your local network. Network problems or communication glitches can disrupt this process, leading to control issues. To address network and communication issues:

  • Check Network Connectivity: Ensure that both your Home Assistant instance and your Daikin AC unit are connected to the same network and have stable internet access. Restart your router and modem to refresh the network connection.
  • Verify IP Address: Confirm that the IP address of your Daikin AC unit is correctly configured in Home Assistant. If the IP address has changed, the integration won't be able to find your AC. You might need to re-discover your device or manually update the IP address in the configuration.
  • Firewall Issues: Check your firewall settings to ensure that Home Assistant is allowed to communicate with your Daikin AC unit. Firewalls can sometimes block network traffic, preventing the integration from working correctly.

4. Daikin AC Unit Compatibility
