post_to_homeassistant

This is a python script to post to the Home Assistant REST API using Long Lived Tokens. This will allow you to control lights, switches and input_booleans using command line arguments.

The goal of this repo is to intergrate Blue Iris into Home Assistant. I've included an example Home Assistant package, see blueiris.yaml. This script is open ended and could be used with any project which is able to execute a python script to trigger a state change.

Two command line arguments are required

post_to_homeassistant.py <entity_id> <state>

Usage example

post_to_homeassistant.py input_boolean.front_door_camera_motion on

Requirements

The requests module is required. Install requests with pip: pip install requests

Configuration

There are two variables which need to be configured

• ha_url - The full url to your Home Assistant instance. Example: http://192.168.2.2:8123
• token - The Long Lived Access Token to be used for the API calls

You will need to edit the script and assign the URL to your Home Assistant instance, as well as the token. You can create a token from your profile page in Home Assistant.

Home Assistant configuration for Blue Iris intergration example:

camera:
  - platform: mjpeg
    mjpeg_url: http://<blueiris server ip>:81/mjpg/FrontDoor  # This needs to be the URL of your Blue Iris web server
    name: Front Door 
    # If you've configured the BI Web Server to not require authentication from
    # LAN connections, remove the the following three lines
    username: !secret bi_username
    password: !secret bi_password
    authentication: basic

binary_sensor:
  - platform: template
    sensors:
      front_door_motion:
        device_class: motion
        value_template: "{{ is_state('input_boolean.front_door_motion', 'on') }}"

input_boolean:
  front_door_motion:
    name: Front Door Motion

This will create a binary sensor (front_door_motion) based on the state of the input_boolean (front_door_camera_motion) which can be controlled using the post_to_homeassistant script.
