This is great info!! Thank you @apostolakisl!!!

Do you know if the GC unit can learn very long IR codes? My understanding is the Mitsubishi Slim remotes sends a number of codes to the units all at once - temp, heat or cool and some other info for example. Much more than a typical IR remote sends. When I use my Mitsubishi remote, I can see my IR repeater in my home theater blink a lot more than it does when using my Harmony remote, for example. I'll see if I can find out more about this today....

I also have Mr. Slims in my home (2 'outside' units and 5 'inside' units. Currently I control them with the remotes that came with them. They are fantastic units. Being relatively new to ISY, I've also started wondering if I could integrate them. I found this: Remotec Z-Wave ZXT-120 IR Extender for Air Conditioners. I can't see where there would be any feedback, but I'm thinking they could at least control my units using my ISY.

This has not happened to me, but in your shoes I would: 1) Disable and then reactivate the 'ISY Optimized for Smart Home V2' skill in Echo (not the devices) 2) As an experiment, try deleting a device or two in your portal, and then adding them back in again to see if your Echo sees them after you do that.

I'm sure some of the more experienced people will jump in here too, but I'll ask an obvious question. Are the devices you want to control with your Echo listed in your ISY Portal? (Select Tool/Connectivity/Amazon Echo)

Headline on the website pointed to: "Experience Alexa on Your Mobile Device or Mac Without Buying an Amazon Echo Speaker Using Reverb" I'm guessing no...
