When using the Echo app to find devices I've noticed the only devices it can find are the ones I had to manually enter in the Insteon Hub. I would open ISY, go down the list and manually enter the address into the hub rather than travel all over the house and link the devices. I've only entered a fraction of the total devices available. I've also noticed the Hub would not accept some devices even though it would accept a nearly identical device. IE: Insteon dimmer wall switch. Two in same box, recognizes one, not the other?

I have the ISY portal set up, the Skill enabled in Echo. Is there a way for Echo to find all the devices available through ISY?

You make known to Alexa the devices in ISY through the portal configuration https://my.isy.io/index.htm Tools > Connectivity > Amazon Echo then ask Echo to discover.  Select Device, Scene or Program then assign it a spoken phrase.

However, seems you also need to setup Connected Home.

Thanks jerlands

Finally got the portal worked out and entered twenty-five devices and a few scenes to test it out.

Have Connected Home set up already and after a few different tries of finding devices if finally connected with Portal and found what I entered.  Now I need to figure out the redundancy of the Insteon hub and ISY as devices loaded in the hub were already found and now loaded twice.

A quick remedy is to Forget All Devices and Groups and run Discovery again.

As Michel pointed out you might consider removing Insteon Hub.
