IFTTT

IFTTT is a web service that allows users to create chains of simple conditional statements, so-called “Applets”. With the IFTTT integration, you can trigger applets through the “Webhooks” service (which was previously the “Maker” channel). This requires the Pro plan or higher.

Prerequisites

To be able to receive events from IFTTT, your Home Assistant instance needs to be accessible from the web and you need to have the external URL configured, or use your Nabu Casa account’s webhook URL from the IFTTT integration.

Configuration

To add the IFTTT integration to your Home Assistant instance, use this My button:

Receiving events from IFTTT

Events coming in from IFTTT will be available as events in Home Assistant and are fired as ifttt_webhook_received. The data specified in the IFTTT recipe Body section will be available as the event data. You can use this event to trigger automations. Use POST as method.

For example, set the body of the IFTTT webhook to:

{ "action": "call_service", "service": "light.turn_on", "entity_id": "light.living_room" }

You then need to consume that incoming information with the following automation:

automation:
- alias: "The optional automation alias"
  triggers:
    - trigger: event
      event_type: ifttt_webhook_received
      event_data:
        action: call_service  # the same action 'name' you used in the Body section of the IFTTT recipe
  actions:
    - action: '{{ trigger.event.data.service }}'
      target:
        entity_id: '{{ trigger.event.data.entity_id }}'
    

Sending events to IFTTT

# Example configuration.yaml entry
ifttt:
  key: YOUR_API_KEY

key is your API key which can be obtained by viewing the Settings of the Webhooks applet. It’s the last part of the URL (e.g., https://maker.ifttt.com/use/MYAPIKEY) you will find under My Applets > Webhooks > Settings.

Once you have added your key to your configuration.yamlThe configuration.yaml file is the main configuration file for Home Assistant. It lists the integrations to be loaded and their specific configurations. In some cases, the configuration needs to be edited manually directly in the configuration.yaml file. Most integrations can be configured in the UI. [Learn more] file, restart your Home Assistant instance. This will load up the IFTTT integration and make an action available to trigger events in IFTTT.

Multiple IFTTT keys

If you have multiple IFTTT users you can specify multiple IFTTT keys with:

# Example configuration.yaml entry
ifttt:
  key: 
    YOUR_KEY_NAME1: YOUR_API_KEY1
    YOUR_KEY_NAME2: YOUR_API_KEY2

Testing your trigger

You can use Developer Tools to test your Webhooks trigger. To do this, open the Home Assistant sidebar, click on Developer Tools > Actions tab. Select IFTTT: Trigger as the action and fill in the following values:

When your screen looks like this, select the Perform action button.

By default, the trigger is sent to all the API keys from configuration.yamlThe configuration.yaml file is the main configuration file for Home Assistant. It lists the integrations to be loaded and their specific configurations. In some cases, the configuration needs to be edited manually directly in the configuration.yaml file. Most integrations can be configured in the UI. [Learn more]. If you want to send the trigger to a specific key use the target field:

The target field can contain a single key name or a list of key names.

Setting up an applet

Press the Create button and Add on If This. Search for Webhooks.

Choose Webhooks service.

Select Receive a web request.

You need to setup a unique trigger for each event you sent to IFTTT.

Add the Then That action. The below example sends a notification to the IFTTT mobile app and adds value1 to the message:

# Example configuration.yaml Automation entry
automation:
  alias: "Startup Notification"
  triggers:
    - trigger: homeassistant
      event: start
  actions:
    - action: ifttt.trigger
      data: {"event":"TestHA_Trigger", "value1":"Hello World!"}

IFTTT can also be used in scripts and with templates. Here is the above automation broken into an automation and script using variables and templates.

# Example configuration.yaml Automation entry
automation:
  alias: "Startup Notification"
  triggers:
    - trigger: homeassistant
      event: start
  actions:
    - action: script.ifttt_notify
      data:
        value1: "HA Status:"
        value2: "{{ trigger.event.data.entity_id.split('_')[1] }} is "
        value3: "{{ trigger.event.data.to_state.state }}"

#Example Script to send TestHA_Trigger to IFTTT but with some other data (homeassistant UP).
ifttt_notify:
  sequence:
    - action: ifttt.trigger
      data: {"event":"TestHA_Trigger", "value1":"{{ value1 }}", "value2":"{{ value2 }}", "value3":"{{ value3 }}"}
