homebridge-isy-hub

THIS BRANCH IS STILL IN BETA

homebridge-isy-hub is a Homebridge plugin that enables HomeKit support for Insteon devices and scenes controlled by the ISY-994i hub.

This plugin finds all nodes linked to the ISY-994i hub and creates the corresponding HomeKit accessory. Nodes are all Insteon scenes and Insteon devices paired to the hub, that are supported by this plugin (see table below).

Changes to the ISY-994i, such as adding, updating or removing nodes, replicate automatically to HomeKit. Further more, optional features such as Stateless Scenes can turn Inteon KeyPads into Stateless Programable Switches.

Key Points

• Easy setup - automatic discovery and management of nodes linked to ISY-994i.
• Stateless Scenes - scenes can act as Programable Stateless Switches. This allows Insteon KeyPads paired to that scene to act as buttons in HomeKit. See below for details.
• Scene ON Level - allows the ON level of a scene to be changed from the default (255 or 100%). This is useful to detect the state of a scene.
• Usage of the REST API for discovery and WebSocket for state change detection.
• Requires correct setup of the Insteon network and ISY-994i. Refer to Insteon and Universal Devices for more info.
• Please note, this is an unofficial plugin. Some features might not work as expected. Please open an issue if found in such scenario.

Supported Hubs

Installation

1. Install Homebridge by following the instructions.
2. After installing,

• if using Homebridge Config UI X:
  1. Search for isy hub in the plugin page and install it.
  2. Follow on-screen instructions on how to setup.
  3. (optional) configure extra features of the plugin.
• if setup is manual:
  1. Run npm install -g homebridge-isy-hub to install it.
  2. Follow the instrcutions below to out find how to configure your config.json.

Configuration

This plugin will auto discover nodes linked to the hub and that are supported.

If installed with Homebridge Config UI X, this plugin can be configured using the GUI.

If configuring manually, below follows a minimal configuration sample with the required parameters only:

"platforms": [
    {
        "name": "ISY Hub",
        "platform": "ISY Hub",
        "hostname": "192.168.x.x",
        "login": "LOGIN",
        "password": "PASSWORD"
    }
]

This minimal configuration is enough for the plugin to work.

For optional and advanced features, refer to the parameters definition below, and the subsequent explanation of all features.

Full Example

"platforms": [
    {
        "name": "ISY Hub",
        "platform": "ISY Hub",
        "hostname": "192.168.x.x",
        "login": "LOGIN",
        "password": "PASSWORD",
        "hidden_nodes": [
            "12345",
            "AA BB CC 1"
        ],
        "stateless_scenes": [
            "12345",
            "5555"
        ],
        "on_level_scenes": [
            {
                "address": "44444",
                "on_level": 76
            },
            {
                "address": "9090",
                "on_level": 76
            }
        ],
        "refresh_interval": 60,
        "reconnect_interval": 30,
        "heartbeat_timeout": 30,
        "rest_timeout": 10
    }
]

Optional Settings

Hidden Nodes

Hides nodes from the auto discovery. If a node already exists, and then is added here, it will be removed (and if removed here, will be added by auto discovery). Requires changing the parameter hidden_nodes, which expects a list of node addresses as strings.

Stateless Scenes

Allows nodes that are Insteon Scenes to act as Stateless Programable Switches in HomeKit. The main use of this feature is in combination with Insteon KeyPads. Although not directly supported, if an Insteon Keypad is linked to a Stateless Scene, it will act as a button in HomeKit. The accessory comes with two actions (buttons presses), the first one for ON and the second one for OFF. These actions can than be configured to control HomeKit in various ways. Requires changing the parameter stateless_scenes, which expects a list of node addresses as strings.

Scene ON Level

Allows nodes that are Insteon Scenes to adjust their ON level. By default, nodes will consider ON the value 255 (or 100%). This value can be changed here if a scene is considered ON on a level different than 255. If multiple devices in a scene dim to different levels, the ON level for that scene should be the average of the device's ON level. Requires changing the parameter on_level_scenes, which expects a list of dicts, each dict composed of two keys:

• address - a scene node address as a string
• on_level - an integer between 0 and 255.

Advances Settings

Refresh Interval

Time in seconds for the plugin to refresh the devices via REST API. This is what enables the auto discovery. If the WebSocket is closed, it is disabled. And when open renabled. Minimum of 1 second.

Reconnect Interval

Time in seconds for the plugin to attempt a reconnect of the WebSocket if it closes or exits with an error. Minimum of 10 seconds.

Heartbeat Timeout

Time in seconds for a heartbeat to be received from the WebSocket when it is open. If the timeout expires, a reconnect is imediatelly attempted. This is paired to what is emitted by the hub (wiht some margin), change with caution. Minimum of 25 seconds.

REST Timeout

Time in seconds for REST API requests to timeout. Minimum of 5 seconds.

Development

This plugin was based on the homebridge-plugin-template repo, thus allowing live code changes. To setup, clone this repo, and configure homebridge to start with the option -P <PATH_TO-homebridge-isy-hub. Further more, to use live code, run npm run watch. Sudo might be required.
