The portal is completely down right now for linking to Alexa. It says it cannot connect. I saw the problem when Alexa was doing the double chime command that she executed the command I gave it, but nothing.
I disabled the Skill, then went to re-enable it from the Alexa app. and it says that they are very sorry they cannot connect to the ISY system.
I am able to login to the ISY Portal and see my ISY and assign Alexa commands.
