zWay Devices missing channels

I have several TKB sockets (And other devices but the TKB;s are the most popular around the home) on my zWave network. zWay knows about them and knows that the multiSensor channel has kWh, W, V and cos (Power Factor).

But openHab doesn’t seem to know about most of them (The multi sensor channel just seems to be interpreted as a single number - no units or anything, where I would expect 4 different sensors with their own unique units )

Is there a way to force openHab to pickup all the channels for a device?
