The puck can be used with Hubitat via a community driver, I didn't publish the driver I have for this device as It's very very chatty and in my opinion causes more network traffic than it provides functionality for...
The steering wheel and the on off switch do not, and will not work with Hubitat, and probably not any other hub except Ikeas...
Both of these devices are explicitly set up for touchlink (direct device to device) and will not send their commands to a Zigbee Hub/Bridge/Coordinator
