We have an Insteon Hub in house now. We can confirm that it works as an Insteon SmartLinc 2412n. However, feedback does not work with it.
To configure it now, add the device via Manual IP on port 25105, type is Automation, brand Insteon, category SmartLinc. Enter username "admin" and password is your Insteon Hub address as printed on your hub without any punctuation.
The "Default Device" field can be used to create a simple Virtual Remote (this is how lighting devices worked before Roomie implemented manifests for everything). Make sure to use no punctuation when entering Insteon addresses for this device.
Feedback can be fixed in a future release. At this time however, it still looks like it has the same limitations of the Insteon 2412N which are that (1) there is no way to get bulk feedback on multiple devices at the same time which means getting status feedback on many lights at the same time is not going to work, (2) there is no way to get a list of connected Insteon devices so you need to input Insteon addresses directly for any command, and (3) the Insteon Hub cannot be auto-discovered.
We have queried Insteon to determine whether they plan any improvements in these areas. Meanwhile, the instructions above allow all basic commands such as LIGHT ON, LIGHT OFF, and similar commands to work now.
Thank you.
