I am having trouble with Alexa/Echo and I think it might be related to Adding my ISY and my replacement HUB 2. My HUB died and I could not unlike everything from the hub before I fired up my replacement. Alexa has started saying that command does not work with that device. I have posted on Insteons website. So I am not sure if its the ISY causing bad links so I was going to start over with the insteon HUB and ISY.
