homebridge-info

Plugin for homebridge providing stats about the running instance.

homebridge-info acts as a server, that emits several infos about the homebridge instance. You can subscribe and display these in the browser frontend.

Features:

• Memory usage
• Uptime
• OS info
• update check for homebridge version

Installation

As usual, plugins for homebridge are installed with npm:

npm install -g homebridge-info

Configuration

Open the config.json file located in your homebridge directory in your favorite text editor. In the platforms section, add info to the array:

{
    "platform": "Info",
    "port": 9876,
    "name": "Homebridge Info Server",
    "updateFrequency": 10000,
    "updateCheckFrequency": 86400
}

The config options are

• port (number): The port homebridge-info listens for requests. The default should work fine. If there's a different service in your network, that uses this port, just enter a unused port number here. Default: 9876

• name (string): Choose any arbitrary name for this plugin. Default: "Homebridge Info Server"

• updateFrequency (number): The plugin will emit updates every n milliseconds, e.g.

  • n = 10000 - every 10 seconds
  • n = 60000 - every minute
  • n = 300000 - every 5 minutes

  Don't set this too low. Default is 10000 (10 seconds).

• updateCheckFrequency (number): The plugin will check for if an updated version of homebridge is available every n milliseconds, e.g.

  • n = 3600000 - once every hour
  • n = 86400000 - once a day

  Don't set this too low. Default is 3600000 (every hour).

Usage

homebridge-info acts as an EventSource which can be subscribed under /api/info:

var eventSource = new EventSource('http://ip:port/api/info');

where ip is the IP address of your homebridge server and port is the port configured for hombridge-info.

To receive events, add a listener to eventSource:

eventSource.addEventListener('message', function(e) {
    var result = JSON.parse(e.data);
    console.log("got message: " + JSON.stringify(result));
}, false);

result is a JSON object with two properties:

• type: either bridgeInfo or bridgeUpdateAvailable
• data:
  • for type === "bridgeInfo":
    • uptime - uptime of the homebridge process
    • heap - heap memory used by the homebridge process
    • osInfo - info about the host
    • hbVersion - The version of the hombridge instance
  • for type === "bridgeUpdateAvailable":
    • updateAvailable
      • true, if the installed version of homebridge is older than the latest release
      • false, if not
      • "unknown", if either the running or latest version could not be determined
    • latestVersion - either "unknown" or the version number of the latest homebridge release

See test.html for an example browser client.
