Multi-Marker Support — Beta

This is a preview release of the new marker system. The config format has changed — see the migration guide below.

What's New

markers[] — multiple map markers

Replace the old show_marker / marker_latitude / marker_longitude fields with a markers list. Each entry is independent and supports its own entity, icon, colour, and tracking settings:

type: custom:weather-radar-card
markers:
  - entity: zone.home         # always-visible home pin
    icon: mdi:home
    color: '#4CAF50'

  - entity: person.john       # follows John when he is the logged-in user
    icon: entity_picture
    track: entity

  - entity: device_tracker.van  # always tracks the van for all viewers
    icon: mdi:car
    color: '#2196F3'
    track: entity

Marker fields

Field	Type	Description
`entity`	string	`device_tracker.`, `person.`, or `zone.*` — position updates live on every HA state change
`latitude` / `longitude`	number	Static position (used when `entity` is not set or unavailable)
`icon`	string	`default` (home SVG), `entity_picture`, or `mdi:icon-name`
`icon_entity`	string	Entity ID for the picture when `icon: entity_picture` — auto-detected from `entity` if blank
`color`	string	CSS colour for default and MDI icons (e.g. `'#FF5722'`). Has no effect on entity pictures.
`track`	`entity` / `true`	Pan the map to follow this marker
`mobile_only`	boolean	Only show this marker on mobile devices
`home_radius`	number	Metres within which an entity-based marker is hidden when at home. Default `500`. Set `0` to always show.

Live entity tracking

Markers with an entity field update their position on every HA state change. Works with device_tracker.*, person.*, zone.*, or any entity with latitude/longitude attributes.

Track resolution

Set track on one or more markers to auto-centre the map. When multiple markers have tracking enabled, the card picks one winner using this priority order:

track: entity on a person.* whose user_id matches the currently logged-in HA user — highest priority. "I am this person, follow me."
track: entity on any other entity — viewer-independent tracking (e.g. a shared vehicle).
track: true — lowest always-on fallback; overridden by any track: entity match.

Ties at the same priority level log a console warning and use the first marker in the list.

Home suppression

Entity-based markers (device_tracker.*, person.*) are automatically hidden when the entity is at home:

If HA reports state: home for the entity, the marker is hidden regardless of GPS accuracy.
Otherwise, if the entity is within home_radius metres of the HA home location, it is hidden.
Set home_radius: 0 on a marker to disable suppression and always show it.
zone.* entities and static lat/lon markers are never suppressed.

Icon colour

Add color: '#hexvalue' to any marker using a default or mdi:* icon to render it in a custom colour. The default home icon switches to an inline SVG so any CSS colour works without extra asset files.

Auto-migration from old config

If your config uses the old show_marker / marker_latitude / marker_longitude / mobile_marker_* fields and has no markers array, the card automatically converts them in memory on load — your existing YAML continues to work without changes. A deprecation warning is logged to the browser console. When show_marker: true is present with no position specified, a zone.home marker is synthesised automatically.

Other improvements since 3.0.1

disable_scroll option — disables map pan/drag while keeping pinch-to-zoom active
show_scale bug fix — was declared but never wired to the Leaflet scale control
useDefineForClassFields: false tsconfig fix — ES2022 target was silently breaking LitElement's reactive properties, causing the card to produce no DOM at all
126 unit tests covering migration, position resolution, track priority, home suppression, and icon rendering

Installation

Copy weather-radar-card.js and the accompanying assets to www/community/weather-radar-card/ and clear your browser cache.

This is a beta release. The marker API is stable but the editor UI for markers is still basic. Please report issues on GitHub.
