Home Assistant ​

Home Assistant is an open source home automation platform. Protocol Launcher allows you to generate official Home Assistant companion app URL handler links and tag universal links.

Usage ​

There are two ways to use this library:

  • On-Demand import from subpaths enables tree-shaking and keeps bundles small.
  • Full Import from the root package is convenient but includes all app modules.

Pick On-Demand for production builds; Full Import is fine for quick scripts or demos.

Select Installation Method

On-Demand
Recommended. Optimized for production.
Full Import
Convenient. Good for quick scripts.
On-Demand
ts
import { navigate } from 'protocol-launcher/home-assistant'

const url = navigate({
  path: '/dashboard-mobile/my-subview',
})
Navigate in Home Assistant

Use the documented server query parameter to select a configured server:

On-Demand
ts
import { navigate } from 'protocol-launcher/home-assistant'

const url = navigate({
  path: '/webcams',
  server: 'My home',
})

Call Service ​

On-Demand
ts
import { callService } from 'protocol-launcher/home-assistant'

const url = callService({
  service: 'device_tracker.see',
  params: {
    entity_id: 'device_tracker.entity',
  },
})

Fire Event ​

On-Demand
ts
import { fireEvent } from 'protocol-launcher/home-assistant'

const url = fireEvent({
  eventType: 'custom_event',
  params: {
    entity_id: 'MY_CUSTOM_EVENT',
  },
})

Send Location ​

On-Demand
ts
import { sendLocation } from 'protocol-launcher/home-assistant'

const url = sendLocation()

Open Tag ​

On-Demand
ts
import { openTag } from 'protocol-launcher/home-assistant'

const url = openTag({
  tagId: '50A3C7C8-1FE7-4BE8-8DC9-06E07D41B63D',
})

Home Assistant documents tags as universal links with the https://www.home-assistant.io/tag/<tag id> format.

On-Demand
ts
import { nfcUniversalLink } from 'protocol-launcher/home-assistant'

const url = nfcUniversalLink({
  url: 'homeassistant://navigate/dashboard-mobile/my-subview',
})

Home Assistant documents the old-style universal link format as https://www.home-assistant.io/ios/nfc/?url=<a URL you could use with the existing URL handler>.

Generated URLs ​

ts
navigate(navigateParams)
// => 'homeassistant://navigate/dashboard-mobile/my-subview?server=My%20home'

callService({
  service: 'device_tracker.see',
  params: { entity_id: 'device_tracker.entity' },
})
// => 'homeassistant://call_service/device_tracker.see?entity_id=device_tracker.entity'

fireEvent({
  eventType: 'custom_event',
  params: { entity_id: 'MY_CUSTOM_EVENT' },
})
// => 'homeassistant://fire_event/custom_event?entity_id=MY_CUSTOM_EVENT'

sendLocation()
// => 'homeassistant://send_location/'

openTag({ tagId: '50A3C7C8-1FE7-4BE8-8DC9-06E07D41B63D' })
// => 'https://www.home-assistant.io/tag/50A3C7C8-1FE7-4BE8-8DC9-06E07D41B63D'

nfcUniversalLink({ url: 'homeassistant://navigate/dashboard-mobile/my-subview' })
// => 'https://www.home-assistant.io/ios/nfc/?url=homeassistant%3A%2F%2Fnavigate%2Fdashboard-mobile%2Fmy-subview'
