Housegard / Origo SA422WS Smoke Detector not recognised

[prijt]

Version: Domoticz 3.5877
Platform: Rpi3
Plugin/Hardware: Arduino & RFLink 433
Description: While trying to link the Housegard / Origo SA422WS Smoke Detector, I get a time out in Learn Switch and while allowing new Hardware for 5 mins (settings), the log shows: Error: RFLink: Unhandled switch type: RM174RF

The RFLink supported device page shows: Origo SA422WF Smoke detector (Receive) - could there be a difference between the WS and WF version?

Im happy to provide more data, lust let me know what & how.

Regards,
Olaf
