Home Assistant: Map Card, a new leaflet based map with WMS and other advanced features
Introducing ha-map-card a new lovelace card, serving as an enhancement to the native Home Assistant map-card, bringing a host of advanced features to the forefront. Built on the foundation of leaflet.
The main features are:
- Custom Tile Layers: One of the standout features is the ability to use custom map tiles. Tailor your map to suit your preferences, ensuring a personalized and visually appealing dashboard. This makes it easy to use OpenStreetMap and other maps inside your dashboards.
- WMS Layer Support: ha-map-card goes beyond the basics by offering support for Web Map Service (WMS) layers. This advanced functionality allows users to overlay additional map information, such as weather data or satellite imagery.
- selecting how an entity is displayed, etc
- more to come, like ImageOverlay & VideoOverlays, legends, etc
TIP
Home Assistant contains a native map card, if you don’t need advanced features like WMS layers it might be a better choice.
