A good place for new ideas to use with Alexa is this thread.
I know it has 1400 replies but you´ll find some good ideas how to use Alexa with openHAB.
I´m currently building rules to get informations that are normally not known in the Alexa world.
Like “Where is Michael” and openHAB will reply through Alexa with my current address based on my phone location.
As Rich already said, it´s easier to help you if you tell us what your goal is and not what your current problem is.
kind regards
Michael
