I also have many (very old) X10 and (older) Insteon units - all are managed by my ISY-994i controller. A few months ago, I decided to buy some Echo devices. In order to make everything work with Alexa, I subscribed to the ISY Portal, modified a few of the programs I had already created with the ISY-994i controller and linked the ISY Portal with my Amazon.ca account - all the lights and devices in my house can now be controlled by voice. Well worth the ISY Portal subscription.
