Google Assistant SDK Custom integration for Home Assistant

About

This integration is a copy of Google Assistant SDK integration with the following additional features:

HTML responses as text from commands to Google Assistant

Why aren't these changes in the core Google Assistant SDK integration?

Due to a bug in the Google Assistant API, not all responses contain text, especially for home control commands, like turn on the lights. The workaround, per the linked bug, is to enable HTML output and then parse the HTML for the text. Because the core integrations are not allowed to parse HTML, this custom integration is needed.

Examples

Nest Guard

Following example allows controlling Nest Guard and getting its status in a text helper. A similar approach, especially the automation that polls the status, can be used for other devices, for which a template, e.g. template light, might make more sense. Here a Template Alarm Control Panel wouldn't work because Google Assistant doesn't allow disarming Nest Guard.

Create a text helper with:

Name: Nest Guard Status
Icon: mdi:shield-home
Entity ID: input_text.nest_guard_status

Create following scripts:

nest_guard_refresh:
  alias: "Nest Guard: Refresh"
  sequence:
    - service: google_assistant_sdk_custom.send_text_command
      data:
        command: what is the status of nest guard
      response_variable: response
    - service: input_text.set_value
      data:
        value: "{{ response.responses[0].text }}"
      target:
        entity_id: input_text.nest_guard_status
  mode: single
  icon: mdi:shield-refresh
nest_guard_away:
  alias: 'Nest Guard: Away'
  sequence:
  - service: google_assistant_sdk_custom.send_text_command
    data:
      command: Set Nest Guard to away and guarding
  - service: script.nest_guard_refresh
    data: {}
  mode: single
  icon: mdi:shield-lock
nest_guard_home:
  alias: 'Nest Guard: Home'
  sequence:
  - service: google_assistant_sdk_custom.send_text_command
    data:
      command: Set Nest Guard to home and guarding
  - service: script.nest_guard_refresh
    data: {}
  mode: single
  icon: mdi:shield-home

Create automation:

alias: "Nest Guard: status"
description: ""
trigger:
  - platform: time_pattern
    minutes: "10"
condition: []
action:
  - service: script.nest_guard_refresh
    data: {}
mode: queued
max: 10

Add the following Entities card in the lovelace dashboard:

type: entities
entities:
  - input_text.nest_guard_status
footer:
  type: buttons
  entities:
    - entity: script.nest_guard_home
      show_icon: true
      show_name: true
    - entity: script.nest_guard_away
      show_icon: true
      show_name: true
    - entity: script.nest_guard_refresh
      show_icon: true
      show_name: true
