homebridge-better-http-rgb

Supports RGB http(s) devices on the HomeBridge Platform and provides a readable callback for getting and setting the following characteristics to Homekit:

• Characteristic.On
• Characteristic.Brightness
• Characteristic.Hue
• Characteristic.Saturation

Installation

1. Install homebridge using: npm install -g homebridge
2. Install homebridge-http using: npm install -g homebridge-better-http-rgb
3. Update your configuration file. See below for examples.

Configuration

Structure

The following is an overview of the structure of your HTTP-RGB accessory.

Both powerOn and powerOff can either be a string or an object. If a string is provided it is filled in as the url and the body will be blank. Most devices will be ok with the string option.

The purpose of powerOff/powerOn for an RGB light is not to physically power or de-power the device (as then how would it respond to further commands?), but to set the LED color to black (for powerOff), and restore the color (for powerOn). Your backend device should already be doing this. This is just a convenience function so that your HomeBridge knows this device can turn off or on.

Additionally, both brightness and color share the same structure (with the exception that the color structure allows for a .brightness variable), they can either be a string or an object. If it is a string, it is filled in as the status and the other fields are left blank. When this is the case, you can only read the settings, you may not change them.

service is one of ['Light', 'Switch'].

RGB Light without Brightness

        "accessory": "HTTP-RGB",
        "name": "Single Color Light",
        "service": "Light",

        "switch": {

        }
    }
]

This normally will not occur, however, you may not want your application to display a "brightness" slider to the user. In this case, you will want to remove the brightness component from the config.

Interfacing

All the .status urls expect a 200 HTTP status code and a body of a single string with no HTML markup.

• switch.status expects 0 for Off, and 1 for On.
• brightness.status expects a number from 0 to 100.
• color.status expects a 6-digit hexidemial number.

http-led-controller

This package was developed in tandem with jnovack/http-led-controller.

I needed a way to control my blinksticks from HomeKit/HomeBridge. After developing this package, I had to have a backend in the event someone's HomeKit/HomeBridge is on a different server, or in my case, there are 4-5 different Raspberry Pi's running blinksticks around my house.

Why 'better'?

As we all know, the word 'better' is subjective, so why put it in the title? I decided to call it 'better' because it is intended to be a 'better' example of how to code, not in the way of a 'better' or more feature-rich project.

There's thousands of projects on github that are just thrown together, half- working, or abandoned and I wanted to make sure that my little contribution to the open-source movement gave more than just code.

The 'better'-project goals are to make sure there is documentation, tests, code and style standards. While I may have missed a few spots, my intention is to ensure that those exist. There is value in documentation, style and testing; and I want to serve as an example to younger (or newer) coders that may be trying to hack apart this project.

TODO

• Perhaps validation of some sort?
• _httprequest should check for non-200
• Better error handling of config errors
