Starting fresh in automation, security panel integration required

[LarrylLix]

ISY home automation integrates with the Elk very well in an all-in-one compact low power box that does it all.
 
The Echo is the latest peripheral absorbed into the ISY994i that people are enthused with. Hue lights, MiLights are all being used with it also.
