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).

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:
- id: this_is_the_automation_id
  alias: "The optional automation alias"
  trigger:
  - platform: 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
  condition: []
  action:
  - service: '{{ 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.yaml file, restart your Home Assistant instance. This will load up the IFTTT integration and make a service 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 -> Services tab. Select IFTTT: Trigger as the service and fill in the following values:

When your screen looks like this, click the ‘call service’ button.

By default, the trigger is sent to all the API keys from configuration.yaml. 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"
  trigger:
    platform: homeassistant
    event: start
  action:
    service: 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"
  trigger:
    platform: homeassistant
    event: start
  action:
    service: 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:
    - service: ifttt.trigger
      data: {"event":"TestHA_Trigger", "value1":"{{ value1 }}", "value2":"{{ value2 }}", "value3":"{{ value3 }}"}
