I have had my ISY994i for about a year and everything was working great. Now, for some reason, several of my devices are no longer responding. There seems to be no rhyme or reason as to which ones quit working (seemingly all at once). I have 2 Insteon Dimmer Switches in my kitchen, located side by side with each other. One works, the other doesn't. I have 3 OutetLinc in my living room, all within 12 feet of each other. Two of them work, the third doesn't. I have 3 outletlincs in the yard to turn on/off the LV lighting. 2 of those work and the third does not. Surprislingly, it is the closest one to the house that DOESN'T work. The ones that are farther down-line are working fine.
If anyone has clues, please help. I'm totally confused.
