(Gradient) Colors Not Applying for LQI (Link Quality Indicator - Zigbee2MQTT) Values (0–255)

[MarvinMynx]

Describe what is wrong
I am using the Battery State Card to display Zigbee Link Quality Indicator (LQI) values with dynamic gradient colors and icons. While the icons work as expected, the gradient colors do not behave as intended. The card fails to reflect the gradient for the defined steps (red, yellow, green) even though my LQI values range from 0 to 255.

Here are the steps I have tried so far:

• Set default_state_formatting: false to prevent default formatting from interfering.
• Used state_map to scale the LQI range (0-255) to percentages (0-100).
• Configured colors with and without gradient: true, as well as with different numbers of steps.
• Defined steps using both color names (e.g., red) and HEX values (e.g., #FF0000).
• Configured steps with and without value fields.
• Changed the order of steps to ensure proper threshold interpretation.
• Tested with and without value_override.
• Attempted different min and max settings for the colors section.

None of these approaches resolved the issue. The colors remain static and do not dynamically reflect the defined thresholds or the gradient behavior.
