I did, get there. What I mean is the page that the docs refer to at IFTTT are not there.
Everything is still there, just add the the Built-in App called IFTTT Integration and follow the instructions in the document mentioned earlier in this thread. Then go to IFTTT.com and setup an account and link it to your hubitat.
I have done all that but I can't figure out what to do after everything is setup. I indicated earlier in this thread, I am not accomplished at programming. I even tried to do one of the simple apps on IFTTT and couldn't make it work. I went through the steps but the button to turn on a lamp never materialized. So I am going to be in deep water trying to setup Hubitat to send SMS when the sytem is triggered.
