Milight Controller Service

This is a simple REST service (not fully REST compliant) to control milight RGB lights. The service uses node-milight to communicate to a milight controller accessible on the network.

NOTE that there is no acknowledgement nor any endorsement from milight.

Setup and Run

1. Install node packages:

npm install

2. Configure the service by editing config.json.
3. Run the service either by calling node:

node milight_server.js

or through npm:

npm start

Configuration

The configuration file config.json is optional and currently the following options are supported:

• milight_host String The hostname of the milight module. Default: 'milight'
• http_port Number The HTTP port to which the server will bind. Default: 8030
• http_host String The hostname (or IP address) to which the service will bind. Default: 'localhost'
• base_url String The URL under which the service is available to the client (public). If not provided, it will be assumed to be http://<http_host>:<http_port>.
• zone_names JSON An optionally partial array of zone id numbers to a String. For example

  "zone_names": {"1": "Dining Room", "4": "Corridor"}
  

Example

If the service is running on localhost port 8030, you can set the light(s) in zone 2 to white with 50% brightness using curl:

curl -X POST http://localhost:8030/zones/2/white/50

API

The API is very simple and tries to be as close to REST (and adheres to {json:api} specs) as it is practically reasonable.

List of Zones

GET /zones HTTP/1.1

Returns the list of zone ids.

Example

http://localhost:8030/zones
---
{
  "data": [
    {
      "id": "1",
      "links": {
        "self": "http://localhost:8030/zones/1"
      }
    }, {
      "id": "2",
      "links": {
        "self": "http://localhost:8030/zones/2"
      }
    },
    ...

Zone Information

GET /zones/:zone HTTP/1.1

Returns information about the given zone, mainly its name and available operations on it.

Example

http://localhost:8030/zones/1
---
{
  "data": {
    "id": "1",
    "name": "Living Room",
    "lastStatus": {
      "brightness": 100,
      "state": "ON",
      "white": 100
    },
  },
  "links": {
    "self": "http://localhost:8030/zones/1",
    "on": "http://localhost:8030/zones/1/on",
    "off": "http://localhost:8030/zones/1/off",
    "bright": "http://localhost:8030/zones/1/bright",
    "white": "http://localhost:8030/zones/1/white",
    "rgb": "http://localhost:8030/zones/1/rgb"
  }
}

Since Milight has no notion of state, the lastStatus information is based on the history of the commands sent to service. If the lights are only controlled by the service, the information is a good representation of the state of the zones.

Update Zone

POST /zones/:zone/:cmd/:param? HTTP/1.1

Changes the zone's light settings based on the given command. Here is one corner where for practical reasons I deviate from REST a bit. The optional parameter is for commands that require a parameter, for example the white command.

Example

http://localhost:8030/zones/1/bright/50
---
HTTP/1.1 202 Accepted

Errors

In case of errors, the reutrned JSON object will have an errors attribute listing all the relevant error messages.

Example

http://localhost:8030/zones/5/bright/50
---
HTTP/1.1 400 Bad Request
{
  "errors": ["Zone '5' does not exist."]
}
