whistle-switch v1.1.7

The Whistle Switch

Control Homekit by whistling 🎶

I built this during my batch at the Recurse Center in 2021. I whistle a lot, and I wanted to put it to some constructive use!

Setup

The easiest way to install the switch is with yarn or npm.

$ yarn global add whistle-switch

If you install it globally, then you can run it from wherever.

$ whistle-switch

Raspberry PI

If you want to run whistle-switch on a Raspberry PI you need to tell it where to find Chromium, because the version from NPM doesn't work the PI's ARM processor.

WHISTLE_SWITCH_CHROME_EXECUTABLE_PATH=$(which chromium-browser) whistle-switch

For more info, check out my post on running headless chrome on a PI.

Connect with Homekit

Once the switch is running on your local network, you should be able to add it to Homekit on your iOS device.

	Select "More Options.." from the Add Accessory card.
	Tap the accessort called "Whistle Switch ..."
	Tap "Add Anyway" when you're prompted about an "uncertified" accessory.
	The default setup code is "123-45-678", but you can change it to anything you want using the WHISTLE_SWITCH_SETUP_CODE environment variable.

Whistle "Buttons"

The switch has three built-in "buttons" that recognize different musical patterns. It'll try to match patterns regardless of key or rhythm.

Note: Right now, whistle-switch only triggers the "Single Press" action.

Advanced Configuration

You'll find the default configs in controller.js. The switch should work just fine with the defaults but you can override them by setting local environment variables.

Resetting the switch

If your whistle-switch gets into a bad state with your homekit setup, you can reset your install.

First off, change WHISTLE_SWITCH_USERNAME in your .env file to a new value.

Then remove the persist directory if it exists.

rm -rf persist

Start the switch again, and you should be able to connect to Homekit as a completely new accessory.
