Per‐Device Operations

Per-Device Operations

Sometimes to do a specific operation, devices need to be queried and set individually. In those cases, actions can be applied to individual devices as well.

// Get some devices
devs := controller.Devices().
	NameMatches("Front Room Light \\d+|Dining Room Light \\d+").
	Query()

// Skip processing if no devices were found
if len(devs) == 0 {
	log.Println("0 devices found.")
	os.Exit(0)
}

// Run each update call in a goroutine to account for API latency
var wg sync.WaitGroup
for i, dev := range devs {
	wg.Go(func() {
		devState, err := dev.Stat(controller)
		if err != nil {
			log.Printf("failed to stat device %s: %v\n", dev.Name, err)
			return
		}

		// Get the current device brightness and increase it by 10%
		if brightness, ok := devState.Brightness(); ok {
			// Increase the brightness by 10%
			next := veego.Percentage(brightness + 10)
			if err := dev.Brightness(controller, next); err != nil {
				log.Printf("failed to set color for %s: %v\n", dev.Name, err)
				return
			}
		}

		// Wait depending on which index the device is
		time.Sleep(time.Duration(1+i) * time.Second)

		// Remove the red from the device color
		if _, g, b, ok := devState.Color(); ok {
			if err := dev.Color(controller, veego.RGB(0, g, b)); err != nil {
				log.Printf("failed to set color for %s: %v\n", dev.Name, err)
				return
			}
		}

		log.Printf("Succeeded with %s\n", dev.Name)
	})
}
