I just received my ISY994i yesterday and spent a lot of time programming it last night. From that experience, I have a few observations/questions -
The Insteon Hub and (I think) Indigo using the same 2413s PLM was able to link with mini remotes and motion sensors by just putting the accessory into linking mode (hold down "set"), while the ISY994 seems to require manually typing in the Insteon address. Is there a technical limitation preventing a more automated linking process for battery-powered devices?
When I added a motion detector and gave it a reasonable name in the dialog box, it created three different nodes all with that name and no obvious way to differentiate which was the sensor, low-battery, and dusk/dawn nodes. After finding no guidance through a web search, I realized that the automatic names that you get if you leave the "name" field blank *do* include suffixes, and then the user is free to rename them from the UI. It was confusing to me at first and I wanted to point it out to other newbies who may be in a similar situation.
I was happy to see the "Start Linking..." option in the menu that allows you to add a bunch of devices at once, but I was disappointed to see that there was no way to rename them until the entire linking process is finished. This led to my having a bunch of nodes with "random" Insteon addresses and no quick-and-easy way to identify which was which to rename them to something meaningful. Rather than trying to turn each of them on and off to figure it out, I just deleted them all and did them in smaller batches. It would have been a lot easier if I could have changed the name right in the growing list as I linked each new device, while it was still fresh in my mind. If there's a easier way to do this, I'm anxious to hear about it.
Overall, I love the device, the flexibility, and how well it works compared to other options.
