Low Battery Alert Smart App

General Discussion
21

This is exactly what I am looking for… do you have this up on github?

22

Not sure why it’s giving that error, but the code is above at the top of this thread. Feel free to tinker.

23

Within initialize, delay the checkBattery using this line:
runIn(60, checkBattery)

instead of checkBattery()

sendPush works fine after the app is initialized.

24

Error when I was attempting to add this app to my IDE. Meta Data not found.

25

They have tightened the IDE since these have been written. If you add definitions to the beginning of the app you’ll be able to publish it. Something like this would do it:

definition(
name: “Low Battery Alert”,
namespace: “macstainless”,
author: “Aaron”,
description: “this app will poll chosen devices that use a battery and send an alert when it’s low”,
category: “My Apps”,
iconUrl: “https://s3.amazonaws.com/smartapp-icons/Convenience/Cat-Convenience.png”,
iconX2Url: “https://s3.amazonaws.com/smartapp-icons/Convenience/Cat-Convenience@2x.png”,

Here is the updated code for everyone. Since this is from the old archived forums, I can’t edit my original post. Hope this helps!

/**

  • Battery Level Alert
  • Author: Aaron Crocco
  • Date: 2016-01-21
  • This app will poll chosen devices that use a battery and send an alert when it’s low.
  • As written, this will:
  •  Poll on the 1st & 15th every month at 10AM

  •  Alert when the batteries are lower than 13%.

I tried this, but it doesn’t like the time/date format that is being used for schedule()

Never mind. If you get rid of the AM it works.
