Button not listed under Contact Sensors

Smartthings has official features which do even more than IFTTT and will do it quicker. So unless you are trying to communicate with devices which don’t have a SmartThings integration, you really won’t need IFTTT. You can do everything ifttt does and much more (including using a button as an “if”) in the official SmartThings features. Smartlighting is one of the most popular features and the buttons will work in that as an “if”. :sunglasses:
