Plantilla de línea de tiempo

Un minigráfico en tiempo real para seguir valores a lo largo del tiempo. Cada envío añade un punto de datos; el servidor acumula el historial y entrega los datos del minigráfico a iOS mediante notificaciones push.

Fields

Field	Type	Description
`template`	string	Required. Must be `"timeline"`
`value`	object	The data point(s) for this push. Required. A labeled map (e.g. `{\"CPU\": 72.5}` or `{\"CPU\": 72.5, \"GPU\": 45.2}`). Max 10 series, 32-char keys
`unit`	string	Unit suffix on value display (e.g. "°C", "%"). Max 32 characters. Used as fallback when `units` is set
`units`	object	Per-series unit overrides. Keys must match `value` keys; missing keys fall back to `unit`. Max 32-char values
`scale`	string	Y-axis scaling: `"linear"` (default) or `"logarithmic"`
`decimals`	integer	Decimal places for display. `null` = auto-detect. Range 0–10
`smoothing`	boolean	Curve interpolation between points. Default: `false` (straight segments)
`thresholds`	array	Up to 5 horizontal reference lines. Each has `value` (required), `color`, and `label` (max 12 chars)
`state`	string	Status text (e.g. "Heating", "Monitoring")
`icon`	string	SF Symbol name (e.g. `"chart.xyaxis.line"`) or MDI icon with `mdi:` prefix
`accent_color`	string	Named color or hex. Default: `teal`

`primary_series`	string	Names which series drives the headline value and the compact high/low range on iOS. Max 32 chars, and must match one of the `value` keys to take effect. When omitted (or naming an unknown key), the alphabetically-first series is used.

`compact_label`	string	Optional, max 4 characters. Replaces the high/low stack in the Dynamic Island compact leading ear. The minimal presentation ignores it.

Each push appends a timestamped data point to the server-managed history, which never needs to be sent: a seed on the first update is honored, but once any history exists a client-supplied history is ignored. Up to 300 points per series are stored; APNs payloads are dynamically downsampled via LTTB to fit 4KB while preserving peaks and visual shape.

Renders url_action and secondary_url_action as buttons below the sparkline; tap_action covers taps elsewhere on the card — see Tap actions.

Example: Single Value

Monitorización de temperatura del servidor

{
  "state": "ongoing",
  "content": {
    "template": "timeline",
    "value": {"Temperature": 13.7},
    "unit": "°C",
    "state": "Heating",
    "icon": "thermometer.medium",
    "accent_color": "orange",
    "smoothing": true
  }
}

Example: Multi-Value with Thresholds

Estado del sistema con unidades mixtas

{
  "state": "ongoing",
  "content": {
    "template": "timeline",
    "value": {
      "CPU": 72.5,
      "GPU": 45.2,
      "Fan": 60.0,
      "SSD": 38.1
    },
    "unit": "%",
    "units": { "GPU": "°C", "SSD": "°C" },
    "state": "Monitoring",
    "primary_series": "CPU",
    "thresholds": [
      { "value": 80, "color": "red", "label": "Critical" },
      { "value": 60, "color": "orange" }
    ]
  }
}

💡 Consejo

Value-only updates are delivered at low priority to conserve the iOS push budget. Changing scale, smoothing, decimals, unit, or units triggers high-priority delivery.

Use Cases

Server monitoring — CPU temperature, memory usage, network throughput over time
Smart home — room temperature trends, humidity tracking, energy consumption
3D printing — hotend/bed temperature curves during a print
CI/CD — build time trends, test suite duration over consecutive runs
