Ah, it looks like you stepped into the bug that @jmccausland stepped into couple of weeks ago. Can you please update to the last version and see if that fixes your problem? To test it, copy/paste the new code. Then go to your mobile app and set the temperature just above your outdoor sensor whatever that might be now. Then click done and wait 2 min and watch it adjust itself. I would do it with live logging on just in case it still not working. Also, when you are in live logging, please click at the top on the name of your app. That way, it will only display the logging from that single app.
Here is the post/link to the most recent updated version:
