Including Ring sensors into a z-wave network

Hi guys, I tried to include my Ring Motion sensor into my existing z-wave network, but failed. I did not succeed with the inclusion although I followed the steps in the manual: ``` After powering on the device, press and hold the button on the front of the device for ~3 seconds. Release the button and the device will enter Classic inclusion mode which implements both classic inclusion with a Node Information Frame, and Network Wide Inclusion. During Classic Inclusion mode, the green LED will blink three times followed by a brief pause, repeatedly. When Classic inclusion times-out, the device will blink alternating red and green a few times. ``` I suppose it's related to the s2 security. Ist there any way to include the Ring sensors into external networks without s2 security? Thanks in advance!
