go.wemo

Simple package to interface with Belkin wemo devices. That has forked from the original package.

This package supports, Belkin Wemo:

• Bridge & Bulbs
• Sockets
• Insight
• Switches & Dimmers

This package also includes a subscription to device events and adds basic device discovery.

Example - Device discovery

package main

import (
	"fmt"
	"github.com/gecgooden/go.wemo"
	"time"
)

func main() {
  api, _ := wemo.NewByInterface("en0")
  devices, _ := api.DiscoverAll(3*time.Second)
  for _, device := range devices {
    fmt.Printf("Found %+v\n", device)
  }
}

Example - Control a device

package main

import (
  "fmt"
  "github.com/gecgooden/go.wemo"
)

func main() {
  // you can either create a device directly OR use the
  // #Discover/#DiscoverAll methods to find devices
  device        := &wemo.Device{Host:"10.0.1.32:49153"}

  // retrieve device info
  deviceInfo, _ := device.FetchDeviceInfo()
  fmt.Printf("Found => %+v\n", deviceInfo)

  // device controls
  device.On()
  device.Off()
  device.Toggle()
  device.GetBinaryState() // returns 0 or 1
}

Example - Control a named light

As a convenience method, you can control lights through a more generic interface.

package main

import (
  "github.com/gecgooden/go.wemo"
  "time"
)

func main() {
  api, _ := wemo.NewByInterface("en0")
  api.On("Left Light", 3*time.Second)
  api.Off("Left Light", 3*time.Second)
  api.Toggle("Left Light", 3*time.Second)
}

Example - Managing Subscriptions

This is an example of discovering devices, subscribing to their events and being notified of changes to their state. Resubscriptions are managed automatically at the timeout specified. Subscriber details and state are maintained in a map.

package main

import (
	"github.com/danward79/go.wemo"
	"time"
  "log"
)

func main() {

  listenerAddress := "192.168.0.6:6767"
  timeout := 300

  api, _ := wemo.NewByInterface("en0")

  devices, _ := api.DiscoverAll(3*time.Second)

  subscriptions := make(map[string]*wemo.SubscriptionInfo)

  for _, device := range devices {
    _, err := device.ManageSubscription(listenerAddress, timeout, subscriptions)
    if err != 200 {
      log.Println("Initial Error Subscribing: ", err)   
    }
  }

  cs := make(chan wemo.SubscriptionEvent)

  go wemo.Listener(listenerAddress, cs)

  for m := range cs{
    if _, ok := subscriptions[m.Sid]; ok {
      subscriptions[m.Sid].State = m.State
      log.Println("---Subscriber Event: ", subscriptions[m.Sid])
    } else {
      log.Println("Does'nt exist, ", m.Sid)
    }
  }

}
