Hi @phjalmarsson,
The problem with these is that by default are included with S0 security. This is buggy with the qubino's and causes them to drop off the zwave network. This does not only happen with Hubitat btw.
The solution is the clumsy way to pair them using a USB stick zwave secondary controller. This topic shows details of how to add such a USB stick (Z-Wave Ghost Removal using a UZB-Stick - How To - #3 by danabw)
PS: if you use Alexa de default drivers will make it show as a Temp sensor with no option to change. You can control the dimmer functions by voice, but not in the alexa app. Here are some drivers to avoid that: Alexa shows wrong device type for Qubino DIN Dimmer
