• The sensor is still defined in the configuration.yaml file. If you create the sensor manually, you will need to remove it from the configuration.yaml file before you can delete it from the UI.
• The sensor is still being used by automation or other configurations. If the sensor is being used by an automation or other configuration, you will need to remove it from that configuration before you can delete it from the UI.

Verify Configuration Files:

Start by checking your configuration files, especially configuration.yaml. Ensure there are no lingering references to the sensor in question. Remove any lines related to the sensor and save the file.
