The remote control is not Hubitat compatible, and in the absence of an official API, it seems likely there'll be an official integration with the Tradri gateway.
The Tradfri LED driver can be paired directly to Hubitat. Here's an old thread on it. This post from @Royski is of particular interest:
I wanted to add - not that I am advocating this, but there is a Node-RED Tradfri integration. Using @fblackburn's Node-RED Hubitat integration (linked below), it should be very easy to create automations that include devices paired to either controller.
