Acc. the Using Zone Activity support article, Zone Activation can be used with motion and door/contact sensors only:
The Homey SDK documentation also states that only devices with the alarm_motion and alarm_contact capabilities can be used for the Zone Activity option:
And acc. the flow cards in the App Store, it seems that the Zooz tilt sensor doesn’t support alarm_contact as capability, what is needed:
Because I don’t use the tilt sensor myself, please check in Developer Tools → Devices which capabilities the tilt sensor supports.
Btw, please use a meaningful topic title in future.
