I am new to this site, so greetings!
Here is a synopsis of my problem: I was using an Iris (by Lowes) security system until Lowes discontinued it. So I switched to SmartThings because most of the Iris devices were compatible. But because the Iris keypad wasn’t easily compatible, I downloaded the ActionTiles app on a tablet to use as a keypad for the SmartThings app. But I soon discovered that the new version SmartThings app was not compatible with SmartThings for home security. Since the original SmartThings Classic app is compatible with ActionTiles as a home security system, I downloaded this app. But it appears that a ‘Code’ is needed for this Classic app. I tried contacting SmartThings Support by phone about this problem on a couple of occasions, but this has been fruitless! Thank you in advance for any assistance you can provide!
