Aeon Multi Humidity

(Brian) #1

I have my Aeon multi in my gun safe. I have it set up to push notify me if there is motion or if the temp gets too high. I cant figure out how to alert me when the humidity rises too high.

(Ben Edwards) #2

I think you are in the SmartApp writing zone for that, as of right now.

I have the code written, but I am running into a problem simulating. It appears the Aeon only sends humidity like every 3 or 4 hours (annoying to test with)

So when I create a virtual humidity device, it reports its evt.value as 40% and not an unformatted number like 40 so when I try to do any math with it I get an error. According to my real Aeon multi events, the evt.value is properly formatted as a number.

—fixed with Double.parseDouble(evt.value.replace("%", “”)) —

Being able to trigger smart outlets via humidity levels would be great! I assume this will be avail soon? Also too bad it reports humidity hours apart. That means things like dehumidifiers will run long using energy when they quite possibly don’t need to be.

You can install this right now by going into your own SmartApps in your account in the IDE site:

It takes a bit of work but usually people can do it.

Of course, once this is officially published it can all be done in the mobile app.

I may give it a try. I’m in IT, but don’t code. I’ll see how handy I want to become in this arena. :smile:

I may wait for the app to be released, but who knows how long that may take.

Thanks, Ben!

I tried to submit the code for publishing but it wouldnt let me select the app in the IDE for the request. Any thoughts why?

(Brian) #9

Give it a try! Its actually pretty easy to do via the IDE. Its mostly copy & paste the code. We can give you step by step if you want.
It would also be nice having someone else test my code and see if they experience the same refresh rate for humidity that I do. Maybe my Aeon is bonkers. :smiley:

(Ron Anthony Quinn) #10

My friend, give me the step-by-step if ya can (just in case). I will be happy to test it!

And thank you!

Log in to

  • Go to the My SmartApps tab
  • Click the + New SmartApp button
  • Name the App anything arbitrary and the same for description and click create
  • Highlight all of the existing code and delete it. Then copy and paste my code in.
  • Click save then click publish>for me
  • The SmartApp will now show up on the ST phone app and you can configure the settings.

(Ron Anthony Quinn) #12

Thanks! I will report back once I have it working. :slight_smile:

Code above has been submitted for publication review.

Also be sure to push the “Configure” button for the Aeon Multicontroller immediately after you get it connected to your hub - this reprograms the default setup so that it remorts humdity every time that the humidity changes.

Then you can test it by blowing on it (seriously - your breath is enough to raise the humidity, if you blow in the right place ;o)

(Ben Edwards) #15

Was it the namespace field? Needs to be populated.

(Brian) #16

sure was. I figured it out after watching your 5/28 dev discussion.
