Thanks, Lee, for your reply. I will start from scratch if I have to, but 1) am concerned that I won't get back to where I am, and 2) given there are 81 controller buttons and 44 responders (= huge amount of work), hoping to find an answer that leaves me roughly where I am now. The old PLM was only involved in a couple of scenes, so not sure why deleting it would have resulted in ~80 scenes disappearing. Hard to believe there is no functionality for "discover existing links and store that in your database" - if no one has an answer for that, I might proceed as you suggest. One side question - I saw the "pro" version supports ... but couldn't find what the limits of the non-pro version are - hoping I haven't run afoul of that?

I just replaced my Houselinc software with an ISY994i. The house has 8 keypads, 17 dimmer switches, 16 inline dimmers, and 3 appliance switches so I didn't want to reprogram everything from scratch. I gave the ISY some controllers to start with and it discovered all but two of the unlinked switches and created over 100 scenes. I had it add in the last two controllers. The I deleted the old PLM (which only had one sunset/sunrise program in it), grouped the keypads, named them all, and put them in folders and went on to look at the scenes. It was down to 20 scenes, and when I did a compare links on one device, it had 42 links and about 60 missing. I'm not sure at which step this happened. Being new to the ISY, I was a little afraid to tell it to do anything as I didn't want it to write back its diminished view of the house to the controllers. So two questions: 1. What caused most of the links to disappear? 2. Is there some way I can get it to rediscover the links (preferably without having to start from scratch since everything is already named and organized)?
