Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Homebridge platform plugin to make virtual accessories as defined by ISY-994i variables.

This plugin is intended to compliment the excellent homebridge-isy-js plugin by rodtoll. While homebridge-isy-js helps HomeKit understand your ISY-controlled Insteon & Z-Wave devices, there are situations where it'd be desirable to trigger an ISY program or Network Resource as well.

For example: I have a TV that receives infrared ON/OFF commands from my iTach WF2IR, which is controlled by my ISY via Network Resources. I can create an ISY program that runs an ON or OFF Network Resource, triggered whenever an ISY state variable's value is modified. And if I name this state variable in a special way (detailed below), this Homebridge plugin will make a virtual accessory available to HomeKit!

Installation

  1. Install homebridge using: npm install -g homebridge
  2. Install this plugin using: npm install -g homebridge-isy-maker
  3. Update your configuration file. See config-sample.json for an example.
  4. Add variables in the admin console of your ISY-994i and have programs run when their values change.

Configuration

"platforms": [ 
  {
  "platform": "isy-maker",
    "name": "ISYMaker",
    "host": "10.0.0.10",
    "username": "admin",
    "password": "admin",
    "prefix": "hb"
  }
]
  • platform - Must be set to isy-maker
  • name - Can be set to whatever you want
  • host - IP address of the ISY
  • username - Your ISY username
  • password - Your ISY password
  • prefix - Your variables' prefix. Default is hb.

Naming Variables

Each ISY variable represents a HomeKit accessory, service and characterstic. Only one service per accessory is supported, but this service may have mulitple characteristics. Services with multiple characterstics are represented with multiple variables---so long as they have a common name and service, these characteristics will be grouped together.

Variables names are composed of 4 or 5 segment, separated by dots. The first segment is the prefix (default hb), and that just flags this variable for use with Homebridge. The second segment is the accessory name (underscores will be displayed as spaces). The third segment is the service type, and the fourth segment is the characteristic type (valid services and characteristics can be found here). The fifth segment is optional, but you can override a characterstic's default props (keys and values are separated by underscores, and N is swapped for the negative - ).

Here's a full example, showing the structure:

     hb.Custom_Thermometer.TemperatureSensor.CurrentTemperature.minValue_N150_maxValue_150
-------|------------------|-----------------|------------------|--------------------------
Prefix | Accessory Name   | Service         | Characteristic   | Optional Props

The plugin will check for changes to the list of variable names every 10 seconds. New accessories will then be added to HomeKit, or new characteristics will be added to existing accessories if it already exists. It works in reverse, and characterstics will be removed if those variables are removed, and if an accessory no longer has any variables, that accessory will be removed as well.

Note: when adding/removing characteristics, you may need to force-quit and re-launch Apple's Home app to get the new UI to render.

Examples

This isn't an exhaustive list of HomeKit accessories (that list would be found here), but here's some common examples. Keep in mind, Apple's Home app doesn't currently support everything (for example, volume), but many 3rd party HomeKit apps do just fine.

  • Switch

    hb.My_Television.Switch.On

  • Outlet

    hb.My_Heater.Outlet.On

    hb.My_Fan.RotationDirection
    hb.My_Fan.RotationSpeed

Lightbulbs

  • Lightbulb

    hb.My_Chandelier.Lightbulb.On

  • Dimmable Lightbulb

Minor bug note

tldr: restart the Homebridge process after making ISY variable name changes to fix realtime updates.

There is a small bug I haven't been able to squash, and I would appreciate if anyone can point out the fix. Normally, realtime updates work great: the Home app is open, you change an ISY variable's value externally, and the associated accessory updates instantly. However, this realtime updating seems to get lost whenever variable name changes are detected and characteristics/accessories are added/removed. The new characterstic will receive realtime updates, but all the other accessories won't. Normal on-demand updates still work fine: when the Home app is closed and reopened, all values are updated. Also, the websocket continues to receive messages, but updating the characteristic with the new value does nothing.

And, stranger: this bug causes realtime updates to other homebridge accessories to be broken too! Which makes me wonder if it's a deeper problem? Everything works fine again after restarting the Homebridge process, so it's not hard to work-around, but I'd like to avoid that requirement if possible.
