Signal Messenger


The signal_messenger integration uses the Signal Messenger REST API to deliver notifications from Home Assistant to your Android or iOS device.

Setup

The requirements are:

  • You need to set up the Signal Messenger REST API.
  • You need a spare phone number to register with the Signal Messenger service.

Please follow those instructions, to set up the Signal Messenger REST API.

Configuration

To send Signal Messenger notifications with Home Assistant, add the following to your configuration.yaml file:

# Example configuration.yaml entry for Signal Messenger 
notify:
  - name: signal
    platform: signal_messenger
    url: "http://127.0.0.1:8080" # the URL where the Signal Messenger REST API is listening 
    number: "YOUR_PHONE_NUMBER" # the sender number
    recipients: # one or more recipients
      - "RECIPIENT1"

Both phone numbers and Signal Messenger groups can be added to the recipientslist. However, it’s not possible to mix phone numbers and Signal Messenger groups in a single notifier. If you would like to send messages to individual phone numbers and Signal Messenger groups, separate notifiers need to be created.

To obtain the Signal Messenger group ids, follow this guide.

Configuration Variables

name string (Optional, default: notify)

Setting the optional parameter name allows multiple notifiers to be created. The notifier will bind to the service notify.NOTIFIER_NAME.

url string Required

The URL where the Signal Messenger REST API listens for incoming requests.

number string Required

The sender number.

recipients string Required

A list of recipients (either phone numbers or Signal Messenger group ids).
