HassBridge

This is an plugin for Indigo Domotics to bridge to Home Assistant using its inbuild MQTT discovery and events system.

It provides a bi-directional bridge for the devices directly controlled by Indigo and allows Home Assitant to be able to be able to control and use those devices. It is able to send actions like button presses to Home Assistant to be able to be handled as events. It also allows for Indigo Variables to be displayed as Sensors in Home Assistant.

Features

• Home Assistant Auto Discovery of published Indigo devices
• Bi Directional control of Indigo connected devices
• Expose keypad and remote button presses as Home Assistant Events and Device Actions.
• Expose Indigo Variables as Home Assistant Sensors
• Allows for customization how Indigo devices are represented in Home Assistant.

Compatablility Warnings

• As of v1.4.0, Fan support will not work with less than Home Assistant v2021.4

Dependencies

MQTT Server

HassBridge uses MQTT to communicate with Home Assistant. If you are using Hass.io you can use one of serveral MQTT addons that are available. Or you can set up your own MQTT/Mosquito server. As long as its setup and availabel to both Indigo and Home Assistant it should work.

Home Assistant MQTT Discovery

In order for Home Assistant to register and use the devices published by HassBridge, the Home Assistant MQTT Discovery must be turned on when you enable MQTT in Home Assistant.

Installation

HassBridge is an Indigo plugin and can be installed by double clicking the downloaded release while on machine that Indigo is installed on.

Configuration

Home Assistant Settings

Config Option	Description
Base URL	The Base URL of your Home Assistant install.
Accept Unvalidated SSL Certificates	Allows you to use selfsigned certs.
Access Token	Access token to allow API access to send events to HA.
HA Event Name Prefix	The prefix for event names being sent to HA. indigo_hassbridge_instant_on for example

MQTT Settings

Config Option	Description
HA Discovery Prefix	The MQTT prefix for Home Assistant Discovery.
Protocol	The MQTT protocol to use. Websockets or TCP.
Server Address	The hostname or IP of your MQTT server.
Server Port	The port your MQTT server listens on.
Use Encryption	Should the HassBridge connection to the MQTT server use SSL/TLS.
Allow Unvalidated Server	Should HassBridge check for a valid TLS certificate.
Username	Username to connect to the MQTT server with.
Password	Password to connect to the MQTT server with.
Set Client ID	Do you want to set a manual MQTT client id. If not a random client id is generated.
Client Id	The client id to connect to the MQTT server with.

Devices to Bridge

Config Option	Description
All Possible Devices	Bridge all devices that are known HassBridge types.
Devices	Select devices to bridge. Use Cmd-Click to select multiple.
Create Battery Sensors	Automatically create HA Battery sensors for devices that are known battery powered devices. Will show low battery when there has been no communications for 24 hours.

Variables

Config Option	Description
Publish	Select which Variables to publish to Home Assistant as Sensors. If the variable is showing true or false it will publish it as a binary_sensor, else it will publish it as a sensor type.

Customization

Config Option	Description
Customization File Path	The full filesystem path to the customization yaml file.

Debug

Config Option	Description
Enable Debugging	Turns on debug logging. Logs a lot. I mean A LOT. Dont do it unless you really need to.

Customization File

HassBridge output to the MQTT server is very customizable. Almost every config options set to the HA MQTT discovery is configurable. The config file is written in YAML and should be simple to work on. You should be used to this type of thing with Home Assistant anyways :).

One of the most used things will be to change the device_class sent to Home Assistant.
This is also customizable in Home Assistant itself if need be.

Sample Customization YAML

devices:
  Driveway Gate:           # Indigo device name
    config_vars: 
      device_class: door   # Home Assisntant discovery config entry

  Outside Backyard West Gate:
    config_vars:
      device_class: door

      device_class: garage
  Some Insteon Switchlink:
    enable_led_backlight_light: True
    backlight_set_mechansim: swl        # this is the older protocol. default is kpl (newer command)   

variables:                        
  front_door_state:                    # Indigo variable name
    name: Front Door State             # Friendly name for Home Assistant
    bridge_type: VariableBinarySensor  # Set this to be a binary_sensor type
    on_value: Open                     # Value to look for for On state for Binary Sensor     
    config_vars:
      device_class: door               # Home Assisntant discovery config entry 
  suite_room_window_state:
    on_value: Open
    bridge_type: VariableBinarySensor
    config_vars:
      device_class: window

Bridge Types

The bridge_type in the main config of a device or variable customization can be set to allow you to override the behavior of the Indigo device and how it is presented to Home Assistant. This changes the mechanims used to talk to the Indigo device when a command for it comes in from Home Assistant, so this may cause erratic behaviour. This should mainly be used when the default mapping by HassBridge is incorrect, and you want to force the correct mapping.
