Unless specifically changed, the Report Status ID is that of the first device added using manual tapping. Any ID can be placed there, it is independent of any SmartLinc links.
It is "normal" to use HouseLinc to create, modify, and/or delete SmartLinc links. The links created by HouseLinc are identical to manual linking. SmartLinc can be a controller, but not a responder (except for status response, but even a non-linked device ID can be used).
Of the four devices that appear in My Devices, only one was linked manually. The other three were linked using HouseLinc - and none of the devices are set to show their status in SmartLinc. In particular, what I refer to as Primary Devices are those that have a load connected. About a half-dozen devices were initially linked manually.
BTW, I'm an experienced Insteon user (since its inception), almost 90 devices, nearly 4500 posts on the SmartLinc forum. Just so you know
