I have been using Insteon hub and devices for about 5 years. After getting the Echo I had to upgrade my hub to one that was compatible with Echo. Got it from Smarthome for $80. Model #2245-222. I put different lights into scenes which I then schedule for off/on times. The Echo then found all my devices (34) and I can also put them into groups such as three lights in my living room and name it living room. I can then tell Alexa to turn on/off/dim living room which operates independent from the Insteon app. I am very satisfied with the integration of the two systems.
