I'd like some help to clearly identify dual-band Insteon devices.
My device list shows some Insteon Models as "(dual-band)" while others don't show that label -- even though they are dual-band.
In particular, I just swapped out an old SwitchLinc Relay "Firmware: 3A (i2 engine)" with a dual-band SwitchLinc Relay "Firmware: 43 (i2CS engine)". This new switch shows as Model SwitchLinc Relay, with no mention of being "dual-band".
I have a number of other Insteon devices installed for which I'd like to determine their dual-band status.
Is it true that modules prior to the i2CS engine will include "dual-band" in their model description whenever it applies?
Is the i2CS engine used only in those Insteon modules with RF radios, and may or may not indicate as being "dual-band"?
Am I missing anything else?
