Adding new functionality to existing ceiling fan remote

[residualimages]

Welcome, @mdarnold !

If the original / OEM remote does not support dimming, then likely the wiring in the light kit does not support dimming – and in any case, if the original / OEM remote does not support dimming, it is 99.9% likely the RF receiver in the ceiling wouldn’t know how to handle a dimming command.

I know that some folks, myself included, have found over the years (even before Bond) that some additional IR commands for things like a TV were stored in and able to be handled by the TV, even if the original remote didn’t have a button for it.
As far as RF ceiling fans, I have yet to find any such examples of a parallel – likewise for others in the community, and the Bond staff have not said otherwise. This is why I’ve said the below, in summary:

As far as devices with supported RF range and types, whatever discrete commands are available on OEM remotes can be recorded into the Bond Bridge / Bridge Pro. The Bond products cannot add new functions, and some things like “hold to dim / release to stop dimming” are not fully supported unless a template match is found for the device upon scanning the OEM RF signals.
