A custom Lovelace card for Home Assistant that displays two concentric gauges to visualize sensor data.
Dual Gauge Card is a custom Lovelace card for Home Assistant that displays two concentric gauges in a single card, allowing users to visualize and compare two related sensor values like current and target temperatures. It solves the problem of cluttering dashboards with multiple cards by combining dual metrics into a compact, intuitive visual element.
Home Assistant users and smart home enthusiasts who want to enhance their Lovelace dashboards with advanced, customizable visualizations for sensor data.
Developers choose this card for its space-efficient dual-gauge design, extensive customization options for colors and thresholds, and seamless integration with Home Assistant entities, offering a visually appealing alternative to standard single-gauge cards.

Combines two gauges into one card, saving dashboard space and enabling direct comparison of related metrics like current and target temperature, as shown in the screenshot and description.
Supports configurable color lists based on sensor values with automatic sorting and inner gauge shading, allowing visual alerts for thresholds like temperature ranges in the example config.
Allows both common and individual settings for min/max, colors, and precision per gauge, overriding as needed, providing fine-grained control as detailed in the config tables.
Works directly with Home Assistant entities and attributes via Lovelace UI, with HACS support for easy installation, as outlined in the installation section.
Card width is fixed in pixels and does not adapt to viewport changes, limiting usability on mobile or varying screen sizes, as admitted in the README's cardwidth note.
The project is actively seeking a new maintainer, raising risks of abandonment, lack of updates, and potential compatibility issues with future Home Assistant versions.
Cannot display more than two metrics; users must rely on multiple cards or alternatives for comparing three or more values, restricting scalability.
Requires manual YAML editing and understanding of entity attributes, which can be error-prone and challenging for users unfamiliar with Home Assistant's structure.
