Capabilty button not working

Developer Programs Writing SmartApps

Hi Guys,

I tried this button capabilty, seems like its not working or I coded wrongly?
here’s the code I’m running…

preferences {
section(“Title”) {
// TODO: put inputs here
input “customButton”, “capability.button”, title: “Select Button”, required: false, multiple: true
}
}

def initialize() {
subscribe customButton, “button”, ButtonHandler
}

def ButtonHandler(evt) {
log.debug evt.value
log.debug “Pressed”
}

What’s not working? Are you not getting a list of buttons to select? Or, is your event handler not getting called?

Hi Linda,

My event handler not getting called

It doesn’t look like you’re ever calling initialize() so the subscription is never happening.

You’ll want to do that when the app is installed (and possibly updated)

http://docs.smartthings.com/en/latest/capabilities-reference.html#button

Edit: this might be easier to see (just a snippet and it’s a different device, but you get the idea)

def installed() {
    log.debug "Installed with settings: ${settings}"

    initialize()
}

def updated() {
    log.debug "Updated with settings: ${settings}"

    unsubscribe()
    initialize()
}

def initialize() {
    subscribe(sensorOpen, "contact.open", contactOpenHandler)
    subscribe(sensorClose, "contact.closed", contactClosedHandler)
}

Have you tried an actual device, or is it just not working in the using a virtual device in the IDE?
I was just able to get a button device working an an app, but the virtual device didn’t work. You can test using physical devices.

Edit: In fact, your app is working for me with my minimote.

Alright Carinda, thanks for your help :smile:

No problem; good luck with the rest of your app
