A minimalistic and customizable graph card for Home Assistant Lovelace UI, displaying sensor history as line or bar charts.
Lovelace Mini Graph Card is a custom dashboard card for Home Assistant that displays sensor data as interactive line or bar graphs. It visualizes historical trends for entities like temperature, energy usage, and motion sensors, helping users monitor changes over time directly within their Home Assistant interface. The card solves the need for a clean, customizable graphing solution without requiring external tools or complex setups.
Home Assistant users who want to visualize sensor history and trends on their Lovelace dashboards, particularly those managing smart home environments with multiple sensors and seeking detailed data representation.
Developers choose this card for its minimalistic design, extensive customization options, and seamless integration with Home Assistant. It offers advanced features like dynamic color thresholds, dual-axis support, and non-numeric data graphing—all while maintaining a lightweight footprint and easy installation via HACS or manual methods.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Offers granular control over graph appearance with features like dynamic color thresholds, configurable UI elements (show/hide icons, legends), and multiple aggregate functions. The README details options such as color_thresholds for value-based color changes and a long list of 'show' settings.
Enables comparison of metrics with different scales by plotting series on separate axes. The entities object includes a y_axis option set to 'secondary', illustrated in the alternate y-axis example.
Can visualize binary sensor states (e.g., motion on/off) using state mapping to convert text values into graphs. The README provides a state_map object example for rendering motion detection timelines.
Available in the Home Assistant Community Store for easy installation and updates, reducing manual effort. The README recommends HACS and includes a badge for one-click repository addition.
Requires detailed YAML setup with numerous nested options, which can overwhelm users unfamiliar with Home Assistant's configuration files. The README's extensive tables for card and entities options highlight this complexity.
Tied exclusively to Home Assistant's Lovelace UI, making it unsuitable for other platforms or standalone use. Installation methods involve adding resources to Home Assistant configuration, as shown in the manual install steps.
May struggle with large datasets or high update frequencies due to configurable points_per_hour and caching. The README notes that bar graphs display a maximum of 96 bars, indicating built-in constraints.
