Template Tiles

Template tiles show custom data using Home Assistant’s Jinja2 template language — the same syntax used in HA dashboards and automations. When a single entity tile isn’t enough, templates let you combine, calculate, and format anything.

Examples

Section titled “Examples”
  • “3 doors open” — Count your open door sensors
  • “72°F / 45% humidity” — Combine multiple readings on one tile
  • “Welcome home!” when you arrive, “Away” when you leave
  • Current energy usage in kWh — Sum across multiple power sensors
  • “Washer done in 12 min” — Countdown based on a timer entity
  • “Next: Team Meeting 2pm” — Pull from your calendar

How It Works

Section titled “How It Works”

Templates are evaluated by Home Assistant’s built-in template API. The app sends your Jinja2 template to HA and displays the result on the tile. Templates re-evaluate when you tap the tile or pull down to refresh the page — there’s no timed auto-refresh.

{{ states.binary_sensor | selectattr('state', 'eq', 'on')
   | selectattr('attributes.device_class', 'eq', 'door')
   | list | count }} doors open

Live Preview

Section titled “Live Preview”

The editor includes a Preview panel with an Evaluate button. Tap it to send your template to Home Assistant’s template API in real-time — you’ll see exactly how it renders before saving. No more guessing whether your Jinja2 syntax is right.

Inline Icons

Section titled “Inline Icons”

Template output can embed SF Symbols with an [icon:symbolName] marker — for example [icon:lightbulb.fill] {{ lights }} on renders the bulb glyph inline on the tile. Several built-in examples use it.

Presets

Section titled “Presets”

Don’t want to write a template from scratch? Start with one of the built-in examples and customize it:

  • Home Status — lights on, lock status, and people home in one tile
  • Lights On — count of lights currently on
  • Doors Open — count of open door sensors
  • Lock Status — how many locks are secured
  • Who’s Home — which tracked people are home
  • Weather — current condition and temperature
  • Temp + Humid — temperature and humidity together
  • Last Motion — the most recent motion-sensor trigger

Each gives you a working template you can edit. (In the editor, this section is labeled Examples.)

Setup

Section titled “Setup”

In the editor, add a tile and switch it to Template mode. Write your Jinja2 template and tap Evaluate to preview it. You can customize the tile’s icon, colors, and size like any other tile.
