Weather sensors not picked up


I tried to link my weather sensors and weather station (all on 433 mhz) to Homey. It works on Domoticz, but I can not make it work in Homey. The 433 mhz sender is working, because Kaku devices work.
But the app does not see them. The same goes for the 868 mhz weather station. I am running latest vorsion of app and Homey.

Suggestions, anybody?
