Paulmann Spot Adapter Zigbee in Homey?

I just bought Paulmann Spot Adapters for the URail system.
I thought it would be straightforward with Homey, but impossible to see/add the adapters.
There is still no Paulmann application in Homey, and given the price of the Homey Pro, I would not buy any additional bridge.
Is there a way to add them in Homey ?

Thank you.

Have you tried adding them as a generic Zigbee device? “Add Device > Homey > Zigbee”

Yes, it’s adding 1 device (not recognizing the 3 one I installed), but switch on/off is not working.
