I hope the Echo "Connected Home" group approves the "ISY/Connected Home integration" soon, as I believe it would bring more people interested in HA to the ISY device. Not being on the list will cause more people to choose one of the other currently supported devices. I am just starting on modern HA and currently just have basic needs like ON/OFF/DIM so it will meet my needs until I gain more knowledge, and keep the basic commands simpler. I work in IT, so I spent a lot of time researching the protocols and devices, and found that Insteon and Z-wave, seemed to be getting adopted well. I have X-10, and IR from before, so the ISY994i/ZW IR Pro sounded like my best bet. The Insteon Hub II sounded OK, but I know I would have quickly out grow it, and have not been impressed by their software solutions. They seem buggy and they still have a Beta web based control solution that has not changed in years, and never added configuration or fixed any issues that I experienced even though their forums indicted they knew about the problems.
Thanks for you products and I am wishing UDI much success with their products in the coming years,
Brent
