(1) 2413U V2.6 [452B] (died a few weeks ago)
As far a as I am concerned, it is time to switch from Insteon to Lutron or something like that. Heck my X10 held up from the late 70's into the 2000's with little or no problems, still have a box full of X10 modules, remotes and other accessories in the shed, that all worked when I switched to Insteon years ago. I am not interested in WiFi or a Cloud based system. I will download the node server for something like the RA2 (since there is nothing available for RA3 yet) and start changing out the Insteon devices. Not sure, but I do not remember seeing any Remote Modules or AC Receptacles for the RA2 or RA3 so I may have to find a work around for those 6 items. Was looking at Zigbee (not sure of its future), but leaning more toward Lutron now.
