Hello, first time user here and I’m unable to make a piston at all and receive the “Not authorized” message much like @FusionDawg. I have OAuth enabled and the install seemed to work fine. I’m using Android on a Nexus 6p if that matters.
I am a long time Tasker user and am looking to move my automation to ST but so far have been feeling extremely limited by it’s abilities and was hoping CoRE was the answer so I hope someone can help me out.
Thanks for any info,
Check your version number. There was an issue with the latest android version 2.2.2. There’s a link a couple of posts up for the older version.
After trying to create my first piston, the cursor blinks a few time and then nothing happens. I went to IDE and looked and it creates a core listing ( see my post above for picture) I looked at the events and the error I see is
“Installed smart app ‘null’ created”
Does anyone know how to fix this. I’m totally lost.
I have uninstalled core 3 or 4 times and uninstalled github once, even unpluged my hub for 10 minutes. Reinstalled everything and still doesn’t work.
I’ve seen your posts about your issue and this is the first time I’ve seen that kind of problem. To recap, what version of the app are you using and on what platform (android or ios)?
Windows 10, Core version is 3.162 and I’m using IOS (Iphone6) any help would be much appreciated.
For any Android 2.2.2 users here hitting the “Not Authorized” issue try updating your _traverseConditions method to the following code:
private _traverseConditions(parent, conditionId) {
Integer conditionIdInt = conditionId instanceof String ? Integer.valueOf(conditionId) : conditionId
if (parent.id == conditionIdInt) {
return parent
}
for (condition in parent.children) {
def result = _traverseConditions(condition, conditionIdInt)
if (result) {
return result
}
}
return null
}Thanks, that worked. I was able to edit and add a piston after swapping code.
I just got a Cooper RF9500 switch and confirmed the device handler is working.
Can someone help setting up a rule when pressing one button increases the dimming level of my lights and pressing another button decreases the dimming level?
Thanks.
Wow!! Smartthings staff supporting community written apps!!!
Will update CoRE shortly. What was it?
THANK YOU
I just got the error again after trying to add a Task.
Hello Everyone, Just wanted to give everyone a heads up that we did have an Android bug that impacted how page params were being passed around. I am happy to report we fixed the issue and have uploaded a new Android version to the store a few minutes ago. The new Android version with the fix will be 2.2.3 and you should start seeing it in the store soon. We were able to post a work around to the original developer to address this issue in the SmartApp. The workaround and the hot fix will work together in case you have updated your SmartApp. Thank you for your patience!
I just downloaded the 2.2.3 update and it seems to be working correctly again. I will test further tonight, but so far so good. Thanks for the quick update.
Big thanks to @rappleg and @kleneau
He’s found and fixed a bug affecting Android ST 2.2.2 and I’ve added it to CoRE - with credits to him, THANK YOU
v0.3.164.20161102 - RC - Fixed a loose type casting causing Android ST 2.2.2 to fail - thank you @rappleg for the fix, also now encoding uri for web requests - may break things
The bug was really me not using strict type casting… the traps of Groovy…
Love the quick response and collaboration. You guys rock… 
Still getting an error setting up the “then” on a basic piston:
org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast object ‘48’ with class ‘java.lang.String’ to class ‘int’ @ line 3495
edit: I hadn’t updated in awhile, it looks like this problem goes back for several months if I roll back to an earlier commit. I guess I should figure out what object 48 is?
I have just successfully created a basic piston.
Have you updated your android app to 2.2.3 and update the CORE smart apps to the latest version?
I was one behind on the apk Thanks. I didn’t notice they had already rolled a new version since yesterday. “Then” works now.
Yep. I had the same issue, but deleted my question when I noticed my phone hadn’t pushed the latest update. 
Well I guess I’ll just live without CoRE unless someone has any solutions. I have done everything that I know of to get it to work again. eibyers also got with me through Team Viewer and tried all that he knows without it working. Just thought I would post this in case someone else runs into the same problem and finds a solution to please let me know. If your not familiar with the problem just read back through my post.
